Summary
Sermorelin (also known as GRF 1-29) is a synthetic peptide analog of growth hormone-releasing hormone (GHRH) that was originally developed by Serono Laboratories and approved by the FDA in 1997 under the brand name Geref for treating growth hormone deficiency in children.
The FDA originally approved Sermorelin for diagnostic use and for pediatric growth hormone deficiency, but the manufacturer voluntarily discontinued production in 2008 due to manufacturing difficulties—not because of safety or effectiveness concerns.
Today, Sermorelin is available only through compounding pharmacies with a valid prescription from a licensed healthcare provider and is used off-label by physicians and anti-aging clinics to stimulate natural growth hormone production in adults.
Unlike synthetic HGH injections that can shut down the body’s natural hormone production, Sermorelin works by signaling the pituitary gland to release more of the body’s own endogenous growth hormone in a more natural, pulsatile manner.
📦 Product: Sermorelin acetate injectable peptide therapy—available as single-dose vials (3mL, 4mL, or 5mL), powder lyophilized form, or pre-mixed liquid injections. Typically administered via subcutaneous injection daily or multiple times per week. Supplied in 5mg, 6mg, 9mg, or 15mg vials depending on the provider and treatment protocol.
🔬 Lab Verified (3rd Party): Quality Sermorelin from reputable providers is synthesized and lyophilized in the USA with purity verification at ≥99% and >99%, confirmed through third-party testing from FDA-approved or FDA-registered compounding pharmacies. Kits typically include syringes, needles, alcohol pads, and detailed administration instructions to ensure consistent quality and safe self-injection.
🚚 Shipping: Standard shipping ranges from 3 to 7 business days for domestic US delivery from compounding pharmacies. Free priority shipping offered on orders over $200 for research-grade peptides from some suppliers.
For prescription-based sermorelin from telehealth clinics, monthly deliveries are typically included with ongoing support. Some providers ship via FedEx or USPS Priority Mail, with tracking included.
💳 Payment Methods: Credit cards (Visa, MasterCard, American Express), PayPal, and bank transfers accepted by most providers. Some research chemical suppliers offer additional discounts (10% off) for cryptocurrency payments.
💯 Money Back Guarantee: Limited money-back guarantees are available. Most research chemical suppliers offer no refunds once products are shipped, though some compounding pharmacies provide 15-day return windows on unopened, sealed products with a 5% restocking fee.
However, many clinical providers offer satisfaction guarantees and protocol adjustments if patients are not experiencing expected results after 3 to 6 months of consistent therapy.
🎁 Promo: Bulk discounts available from research suppliers—5% off when purchasing 5 to 8 units, 10% off when purchasing 9 or more units. Subscription-based models from clinical providers typically offer better long-term pricing than one-time purchases.
💲 Price: Cost varies significantly based on source and whether it’s research-grade or prescription-based through a healthcare provider. Research-grade lyophilized peptide: $38.70 to $50.00 per 5mg vial with bulk discounts. Some clinics offer monthly plans starting at $195 to $225, with packages ranging from $528 to $600 for quarterly supplies.
⚠️ FDA Status & Legal Considerations: Sermorelin is no longer FDA-approved for any use after voluntary discontinuation in 2008 and is now available only through compounding pharmacies with a valid prescription.
It was never approved by the FDA for use in adults—only for pediatric growth hormone deficiency. All adult uses are off-label and require a doctor’s prescription. Sermorelin is not a controlled substance and physicians can legally prescribe it off-label for adult growth hormone deficiency and anti-aging purposes, but it must be obtained from FDA-registered or FDA-approved compounding pharmacies to ensure legality and safety.
⚠️ Common Side Effects: Most side effects are mild and occur at the injection site, including swelling, redness, itching, pain, and sensitivity. Systemic side effects (affecting the whole body) are less common but may include temporary headaches, nausea, dizziness, flushing, difficulty swallowing, and mood changes.
Rare but more serious potential side effects include water retention and swelling (edema) in the arms, legs, and face, joint and nerve pain, increased insulin resistance and diabetes risk, and cardiac problems with chronic use (hypertension, cardiac hypertrophy, or cardiomyopathy). Sermorelin obtained from unregulated or black-market sources may be contaminated or mislabeled, posing additional health risks.
Pros
✅ Noticeable Improvements in Sleep Quality Within Days – Multiple users on Reddit, Trustpilot, and clinical reviews report experiencing deeper, more restful sleep within the first week of treatment, with many describing it as one of the most noticeable and consistent benefits. Users mention going from waking up at 2-3 AM unable to sleep to sleeping solid 7-8 hours per night.
✅ Faster Muscle Recovery and Reduced Post-Workout Soreness – Numerous testimonials from users within weeks 3-4 of therapy consistently report significantly improved recovery from workouts, with muscles feeling less sore and greater ability to train harder the following day. This allows for more frequent and intense training sessions without excessive fatigue.
✅ Visible Body Composition Changes (Fat Loss + Muscle Gain) – Many users on Trustpilot and Reddit report visible improvements in muscle definition and body composition within 2-3 months of consistent therapy, with some mentioning losing 15-30 pounds while gaining muscle. Women report approximately 15% average body weight reduction over 68 weeks of therapy.
✅ Natural Hormone Stimulation Without Direct Synthetic HGH Injection – Unlike direct growth hormone injections that can shut down the body’s natural hormone production, sermorelin works by signaling the pituitary gland to produce more of the body’s own growth hormone in a natural, pulsatile manner, making it a safer long-term option.
✅ Improved Energy, Mental Clarity, and Mood Stability – Users consistently report feeling more energized throughout the day, improved focus and mental sharpness, and better overall mood stability within 2-3 weeks of starting therapy. Many describe it as feeling like a general enhancement of overall well-being.
✅ Improved Skin Quality and Anti-Aging Effects – Some users report improvements in skin texture, thickness, hydration, and a reduction in fine lines and wrinkles, with descriptions of skin appearing firmer, smoother, and more youthful-looking, particularly after 3-6 months of consistent therapy.
✅ Fast and Discreet Shipping with Excellent Customer Service – Trustpilot reviews highlight fast delivery times (typically 3-7 business days for US shipments) and professional, discreet packaging. Many providers are noted for responsive customer service that quickly resolves shipping delays or order issues.
✅ Available Through Multiple Payment Methods – Most telehealth providers and clinics accept credit cards, PayPal, and bank transfers. Some research chemical suppliers offer cryptocurrency discounts (10% off) or subscription payment plans that reduce monthly costs.
Cons
❌ High Monthly Cost ($200–$500) Requires Ongoing Financial Commitment – Sermorelin therapy is expensive, averaging $200-$400 per month through legitimate telehealth clinics, with some providers charging up to $500 monthly. This does not include additional costs for syringes, needles, alcohol swabs, or doctor consultations, making long-term therapy a significant financial burden for many patients.
❌ Results Develop Gradually—No Immediate or Dramatic Changes – While some users notice sleep improvements within days, most physical and body composition changes take 3-6 months or longer to become noticeable. Some users on Reddit reported seeing minimal changes after 3 months, which can lead to disappointment and treatment discontinuation.
❌ Risk of Fake or Contaminated Products from Unregulated Sources – A significant concern is that products purchased outside of legitimate telehealth clinics or compounding pharmacies may be counterfeit, contaminated, expired, or improperly dosed. Some Reddit users and reviews report purchasing sermorelin and finding no results or having their growth hormone levels actually decrease.
❌ Potential Serious Side Effects (Water Retention, Joint Pain, Carpal Tunnel) – While common side effects are mild (injection site redness, headaches, nausea), more serious potential side effects include water retention and swelling in arms, legs, and face; joint pain; carpal tunnel syndrome; increased insulin resistance; and in rare cases, high blood pressure or heart problems with long-term use.
❌ Requires Consistent Daily or Multiple Weekly Injections – Sermorelin must be administered via subcutaneous injection 5-7 days per week (typically in the evening), which is less convenient than oral supplements and requires users to be comfortable with self-injection. Some people find the injection process intimidating or inconvenient to maintain long-term.
❌ Limited Insurance Coverage and Additional Out-of-Pocket Expenses – Most insurance companies do not cover sermorelin therapy for anti-aging purposes, meaning the entire cost is out-of-pocket. Additionally, patients must budget for syringes, needles, alcohol swabs, and periodic lab testing to monitor growth hormone and metabolic markers.
❌ Lack of Independent Third-Party Clinical Evidence for Anti-Aging Claims – While clinical studies support Sermorelin’s use for treating growth hormone deficiency in children, much of the anti-aging and body composition benefits reported by users are self-reported testimonials and not verified by large-scale peer-reviewed clinical trials in healthy adults.
❌ Mixed Reviews Regarding Effectiveness – Some users on Reddit and Trustpilot report minimal or no noticeable results despite consistent use for 3+ months, while others report significant improvements. This variability in outcomes suggests that individual response can be unpredictable and depends on many factors (age, baseline hormone levels, lifestyle).
❌ Requires Prescription from Licensed Healthcare Provider – Sermorelin is not legally available over-the-counter and requires a valid prescription from a licensed physician or nurse practitioner, which involves doctor consultation fees ($0-$100 depending on provider) and ongoing medical supervision.
User Review
( votes)What is Sermorelin?
Sermorelin, also known as Mod GRF 1-29, is a peptide that stimulates HGH synthesis. However, the synthetic substance, similar to endogenous, has an extremely short half-life. To increase this parameter, four amines were added to the molecule. This peptide was named Mod GRF 1 29.
This structural modification has increased the duration of action to 30 minutes, which is enough to achieve a lasting effect and stimulate the peak secretion of growth hormone. This form is also often referred to as tetra-substituted GRF (1-29) or modified, and is very often confused with CJC-1295.
If we draw an analogy with an anabolic steroid, then tetra-substituted GRF (1-29) is an analogue of testosterone propionate, and CJC-1295 – testosterone enanthate.
TIP! When buying this peptide, be sure to specify whether this form is tetra-substituted (modified) or not.
Because of the connection with plasma proteins, tetra-substituted Sermorelin is also known as CJC-1295 without DAC (Drug Affinity Complex – a special complex that extends the duration of action to several days).
To create a more convenient, long-lasting form, CJC-1295 was created. This peptide is similar in structure to the considered tetra-substituted GRF (1-29), except that the amino acid lysine was added to the sequence, which is associated with a molecule called “Drug Affinity Complex (DAC)”. This complex allows peptides to bind to blood albumins and increases the half-life to 1-2 weeks. By analogy with testosterone, this form can be compared with testosterone cypionate.
Sermorelin peptide is one of the most popular endogenous somatotropin secretion stimulants. The product is not hormonal and does not affect the endocrine system at all. This article will tell you about the correct use of GRF peptide (1-29) in bodybuilding.
How does Sermorelin work?
The peptide stimulates the production of endogenous somatotropin and does not interfere with the endocrine system. This is common to all peptides, which distinguishes them from steroids. Although Sermorelin’s half-life is short, it does an excellent job of increasing the concentration of HGH.
It should be noted that the drug belongs to the group of GHRP peptides and is one of the safest of them. The molecule has much in common with the endogenous substance GRF 1-44.
According to clinical research on Sermorelin’s efficacy on IGF-1 and body composition published in [Khorram et al., Journal of Clinical Endocrinology & Metabolism, 1997], Sermorelin injections in elderly subjects (aged 55-71) demonstrated significant clinical benefits. The 16-week study showed significantly elevated IGF-1 levels after just 2 weeks of sermorelin treatment (10 mcg/kg nightly), with levels remaining elevated through the 12-week measurement point. Male subjects demonstrated increases in lean body mass averaging 1.26 kg (2.8 lbs) with improved waist-to-hip ratios. The research confirmed that Sermorelin could increase lean body mass and facilitate body fat reduction independent of age, with sustained IGF-1 elevation lasting up to 2 weeks after discontinuation.
As we mentioned above, one of the main advantages of this preparation is its high safety. This is proved by the fact that in the United States, the drug is prescribed to children with problems with the production of endogenous human growth hormone. Besides, in medicine, the peptide is used by people suffering from rapid weight loss.
Sermorelin can accelerate the production of one of the isoforms of insulin-like factor – MGF (mechanical growth factor).
The peptide is also able to influence the pituitary gland and thus increase the somatotropin concentration. After that, the active component of the drug is converted directly into an insulin-like growth factor. This biochemical reaction can significantly accelerate the basic metabolism and stimulate the processes of hypertrophy in muscle tissues. Thus, athletes can recover more quickly after heavy training.
Sermorelin benefits and efficiency
Since the drug stimulates the production of such a powerful natural anabolic as HGH, it quickly became popular among athletes. It belongs to the GHRH group and is also the safest.
According to research on Modified GRF 1-29 and Ipamorelin synergistic effects published in [Biotech Peptides Research, 1998-1999], the combination of Modified GRF 1-29 and Ipamorelin demonstrated concentration-dependent growth hormone secretion elevation. Animal model studies using rat pituitary glands, anesthetized rats, and conscious swine evaluated the peptides’ activity. The research indicated that both peptides acted as agonists of GHRP-like receptors, stimulating significant increases in growth hormone secretion with high receptor specificity. Critically, unlike other growth hormone secretagogues, this combination “very surprisingly, did not release ACTH or cortisol in levels significantly” even at significantly high concentrations. Clinical trials showed marked elevation in circulating growth hormone levels throughout the study duration, suggesting a concentration-dependent response to the blend.
Among the main effects of Sermorelin can be noted:
- The increase in muscle mass.
- Fat deposits in the body are reduced and lipolysis processes are accelerated.
- The improvement of the quality of connective tissues.
- The strengthening of the immune system.
- The work of the cardiovascular system will normalize.
Does Sermorelin work well for weight loss in females and males?
Sermorelin injections for weight loss help burn excess fat and increase fat utilization by stimulating triglyceride degradation and adipocyte oxidation. The best peptide combination for fat burning and shedding pounds would be HGH-176-191+Sermorelin. The recommended dosage for weight loss would be as follows:
- HGH 176-191 – three times a day at 220 micrograms.
- Sermorelin three times a day at 110 micrograms.
To get the maximum possible result, you will have to follow a dietary program that limits the amount of carbohydrates in your diet.
Sermorelin in bodybuilding
Since it is possible to gain muscle mass and accelerate fat burning processes, it is mainly used by bodybuilders. In other sports disciplines, however, Sermorelin will not be as effective as it has practically no effect on physical parameters. There are many peptide cycle stacks, and this peptide can be included in almost any cycle.

Sermorelin cycle in bodybuilding
Dosage
The single Sermorelin dosage must be calculated individually by each athlete. Specialists in sports medicine recommend administering 1-2 micrograms per kilo of body weight two or three times a day. So, every day it is necessary to administer two or three Sermorelin injections at a single dose of 100 to 200 mg.
When and how to give injections?
It is desirable to give injections on an empty stomach, at least half an hour before a meal. It is recommended to eat food that contains a minimum amount of carbohydrates and fat. The scheme of Sermorelin peptide taking in bodybuilding we have considered now applies to the solo cycle. In any cycle stack, the peptide should be used in the amount of one microgram per kilo of body weight.
For example, a woman weighing 70 kg wants to conduct a solo Sermorelin cycle. To do this, she must give 140 mg three times a day (morning, lunch, and evening). For dilution of the powder, we recommend using water for injections. The peptide is injected with an insulin syringe into the fat fold of the abdomen. The duration of the course is 60 days. After that, you need to take a break for at least 2 months.
For the solo cycle, Sermorelin, like other peptides of this group, is used very rarely. You will get better results with stacks. It is important to note that the combination of several peptides does not increase the risk of side effects.
The most popular stacks will be Sermorelin and GHRP-1 or 2. There is no point in using both of them; it is enough to choose one and inject 100 micrograms in a single dose simultaneously with Sermorelin. The duration of the cycle is in the range of 6 to 12 weeks. To get the maximum effect, you should inject peptides immediately after training, a quarter of an hour before a meal, as well as before going to bed.
How to properly store
- At -18 degrees Celsius, the powder form retains all of its properties for five years.
- The powder can be stored for up to 24 months;
- The maximum period of storage of the powder form at room temperature is six months;
- The prepared solution should be kept at a temperature of +2 to +8 degrees for a maximum of 20 days.

It should also be noted that the price of the peptide is not very high. Any athlete can afford to buy Sermorelin at this cost.
Sermorelin cycle stacks
To increase the effectiveness of the preparation, it can be combined with other peptides. Let’s look at some examples of such cycles:
Cycle of Sermorelin and GHRP-2 or GHRP-6
The single dosage of Sermorelin is 0.1 to 0.2 mL. It should be injected three times a day. The single dose of GHRP-2 or GHRP-6 is 0.1 ml. The peptide is also injected three times a day.
Sermorelin and Ipamoreline Stacking
The human growth hormone-releasing peptides Sermorelin and Ipamorelin (GHRH or GRF) activate the pituitary gland. When compared to other hormones in their class, known as growth hormone secretagogues, these peptides are shown to be extremely well tolerated and do not cause the same stimuli of hunger or rise in cortisol as those other hormones.
These are helpful in the treatment of osteoporosis, obesity, and many chronic inflammatory disorders, in addition to age-related problems. Sermorelin and Ipamorelin have a lot of advantages:
more vitality increased sex drive increased lean muscle mass decreased body fat improved sleep increased bone mineral content quicker recovery from exercise and accidents increased mental clarity increased collagen synthesis and skin elasticity
Sermorelin is injected three times a day, and its dose is 100-200 mcg.
The frequency of injections of Ipamorelin is similar, and the single dose is 0.1 milligrames.
What other peptide stacks are common in bodybuilding?
Let’s look at the most popular and best peptide stacks for different purposes:
TB-500 cycle
This peptide allows you to improve the function of the joint and ligament system as well as strengthen the connective tissue. TB-500 peptide may also be very useful during the treatment of trauma, as it significantly accelerates the recovery process. Another advantage of the drug is its ability to increase endurance. This made the drug popular among those who are into cyclic sports.
It should be noted that TB-500 was studied a long time ago. The main problem was choosing the most effective dosages.
CJC-1295 and GHRP-2 or GHRP-6 Stacking
This cycle is one of the most popular among bodybuilders. With its help, you can gain about 10 kg of muscle mass. These are the maximum results, which cannot always be achieved. However, about six or seven kilograms are guaranteed to you. The only disadvantage of this combination is the large number of injections since each peptide must be placed three times a day.
Cycle of CJC DAC and Peg MGF
This cycle attracts athletes by allowing them to simultaneously increase muscle mass and get rid of fat. Besides, the drugs work even if you miss the workout. Of course, the possibility of not working out and gaining muscle mass is out of the question. If after the previous cycle it is possible to have a small loss of muscles, this stack guarantees it won’t happen.
GHRP-2 and the CJC DAC cycle
The most budget-friendly option for the use of peptides. It will bring you good results. This stack of peptides can be recommended to athletes who want to get acquainted with how the peptides work.
Peg MGF and GHRP-6 cycle
Another combination of peptides, which is very popular with athletes during the muscle-gain period, On average, athletes gain about six kilograms per cycle with no after-cycle loss. The recommended cycle duration is 1.5 months.
Stacking CJC DAC with Gonadorelin and Ipamorelin
This cycle is designed to increase power. Adipose tissue is actively burned during the cycle, which will allow you to improve the shape of your muscles. This combination of peptides is the most popular among weightlifters.
GHRP and the CJC-1295 stack
Another stack that is in great demand among bodybuilders. It can safely be called universal. It helps in increasing power and gaining muscle mass at the same time. In two months of using it, you can gain about eight kilos on average. It can be recommended to bodybuilders since, in power triathlon and weightlifting, weight gain can lead to a transition to a heavier weight category.
We have considered only a few popular peptide cycles, which are used in sports. To a large extent, their popularity is associated with high efficiency and safety. This is exactly what bodybuilding enthusiasts need.
