Peptides are popular among bodybuilders, as they help promote muscle growth, and the repairing process. There is a wide variety of peptides available in the market, making it difficult for bodybuilders to select the best.

Enlisted below are the most popular USA peptides with their beneficial effects on muscles. Read their effects and select the one that best suits your needs…  

Growth Hormone-Releasing Peptides (GHRP)

GHRP is a well-known peptide among bodybuilders, because it helps them increase muscle mass while losing extra fat. Out of all GHRPs, GHRP-6 is considered the most effective. It provides your body with ghrelin, also called the ‘hunger hormone’, which increases appetite and food intake. This makes GHRP-6 a great choice for bodybuilders who struggle to meet their calorie needs.

It shows its effects within a half-hour of taking it.


Hexarelin is another GHRP. It promotes the synthesis of human growth hormones in the body, increasing muscle cell regeneration.

Bodybuilders put extra pressure on their muscles, so their muscles need more time to heal before the next workout session starts. Hexarelin helps in healing muscles fast. It may also support bone health, reducing the chances of bone fractures and other bone issues that occur later in life.  


Ipamorelin is a relatively new peptide. It acts like ghrelin and stimulates the production of growth hormones from the pituitary. Though it increases the production of growth hormones, it does not stimulate your appetite. This makes it suitable for bodybuilders who consume the right number of calories every day.   


This peptide is effective in increasing the production of cells and muscle tissue. It does this by inhibiting myostatin synthesis. Myostatin is a growth differentiation factor that impedes muscle cell differentiation, as well as muscle growth. Therefore, bodybuilders who take follistatin notice an increase in their muscle mass above normal levels.


CJC-1295 promotes the production of plasma growth hormones. It works like the peptides that we have mentioned above.

There are two forms of CJC available in the market – CJC-1295 and CJC-1295 DAC. The latter form is a modified version of the original peptide. It has a longer half-life compared to the other, due to which it is taken once a week, while CJC-1295 injection is taken three times per day.

Another peptide we would recommend is melanotan 2, which is available from PeptidePros.net.

The Process of Injecting Peptides

Peptide injections are subcutaneous. It means they go a little beneath the skin surface. The best sites to inject these injections are the upper arms, lower back and thighs.

Here is a step-by-step guide to injecting peptides.

  1. Select the site of your injections.
  2. Wash, and then dry your hands.
  3. Clean the injection site with an alcohol wipe.
  4. Prepare the injection according to the guidelines written on its cover.
  5. Pinch your skin lightly with your index finger and thumb.
  6. Insert the needle into the selected area.
  7. Release all the peptides in your muscle.
  8. Take the needle out and dispose of it, so that no one can use it again.
  9. Apply pressure on the injection site with a cotton ball.
