Peptides are hormones produced by the pituitary gland, a small organ that is present in the neck just below the voice box and just above the eyes. The job of the pituitary gland is to secrete the hormones thyroxine, testosterone, and others which are essential in maintaining healthy muscles, tissues, and the overall wellbeing of an individual.
The role of these hormones in promoting muscle growth is what makes peptides important for bodybuilders. Several peptides have important physiological functions in humans including human growth hormone (HGH) and testosterone in combination with others. Some peptides have more impressive effects in terms of stimulating the significant secretion of the growth hormone 1, while others produce lesser effects.
Peptides that have stimulating effects on the growth hormone release are usually considered effective supplements for fat loss and cutting, while those that stimulate the secretion of testosterone are usually the best for muscle building purposes.
The secretion of HGH through the pituitary gland has a significant effect on muscle development and strength. This is because the higher the levels of HGH in the blood, the more calories a bodybuilder can consume without much difficulty. Some naturally occurring peptides increase HGH levels as well as provide other benefits to the bodybuilder.
Many reviews from athletes indicate that peptides
- Break down fat, remove toxins, and improve well-being;
- Shorten the recovery period after sports injuries and excessive training;
- Participate in the building of lean muscle mass
- Some reviews on peptides also show that they increase strength levels. It will be easier to endure intensive and cardio workouts.
Physician reviews of using peptides
- Regulators help to strengthen cartilage and joints, 2 which is especially important during the periods of intense muscle and tubular bone growth (which is important when taking growth hormone or somatotropin cycle);
- Strengthen the immune system, 3 which makes you more resistant to external negative factors during preparations for competitions or while recovering from illness;
- Improve the metabolism, which leads to a comprehensive cleansing of the body of toxins, fats, and detoxes.
Peptides can also cause drowsiness and weakness. If you do not follow the instructions of the drug and do not consult a doctor about the duration of the cycle.
Ordinary people who have taken peptide regulators note that they
- Slow down the aging process, have a rejuvenating effect. The skin becomes firm and radiant. The effect lasts for several months;
- Contribute to effective weight loss
- They participate in the production of melanin, due to which the skin gets beautiful and even tan. This is especially important for bodybuilders preparing for competitions;
- Increase the physical activity endurance;
- Normalize sleep and mental health – it becomes easier to endure difficult life situations, it copes with depression and apathy without psychotropic drugs.
It is important to understand that the effect of peptides extends to many metabolic processes. Someone notes an increase in appetite while the others mild nausea. In this case, you can combine bioregulators with other supplements or adjust the dosage of the drug.
Amino-acids found in peptides
One of the most commonly used amino-acids in sports supplements is L-Arginine, which is produced by the liver. It is found in foods such as meat, dairy products, fish, and some legumes. Interestingly, research studies have revealed that there is a relationship between elevated intake of this amino acid and increased growth hormone production. As a result, researchers have come up with several different arginine peptides and have tried to determine which one has the best effect in promoting growth hormone release.
Another amino-acid with stimulating effects found in peptides is Glycine, which is found in milk, cheese, chicken, and some vegetables. It plays an important role in regulating food consumption by slowing down the emptying process of the stomach, reducing body fat, and stimulating nutrient absorption. Other important peptides include glutamine, lysine, arginine hydrochloride. These compounds have been proven to decrease body fat by increasing energy expenditure, decreasing body fat, and enhancing metabolism.
Some peptides have impressive muscle-building properties, while others are highly useful in relieving common everyday aches and pains and easing joint and tendon stiffness. There are a lot of different amino acids that have different applications.
Each one works differently in different bodybuilding situations. To get the best peptides for bodybuilding you have to choose the ones that will give you the right results. Don’t forget to check the label when buying supplements so you’ll know exactly which type of amino acid you’re getting.
Now that you know what peptide can do for you, you can check many reviews of different peptides for different goals (muscle building, cutting, fat loss…) in our bodybuilding peptides section of the site.
