Buying GHRP 6 vs GHRP 2 for Laboratory Purposes

buy GHRP 6 vs GHRP 2 peptides

Growth hormone is a naturally occurring peptide, which plays a key role in the growth and development from adolescents, to maturity. It is also used to help maintain other key functions such as; cellular growth and regeneration, metabolism, and homeostasis. Studying these hormones have allowed scientist to create similar functioning peptides right in the laboratory. These peptides have been named GHRP. There are two different versions of this and many wonder what difference they have. Here is a breakdown of GHRP 6 vs GHRP 2.

What is GHRP?

Growth hormone releasing peptides (GHRP) are synthesized in laboratory to mimic the function of growth hormone. They are not found naturally occurring and come in more than on form. Two of these forms are GHRP 2 and GHRP 6. While they both known as GH Secretagogues and allow for the release of growth hormone from the pituitary gland and the hypothalamus, their functions and side effects are not exactly the same. They work by activating a protein receptor. It is important to note that GHRPs are in no way structurally similar to the naturally occurring growth hormone releasing hormones.


The first of its kind, GHRP 6 is a laboratory synthesized peptide to aid in the release of growth hormone. In animal test subjects it was found to be useful in treating obesity and other eating disorders. However, due to it being the first generation peptide some problems did arise, as it had some unwanted effects like increasing hunger and gastric motility.

It works as an appetite stimulant by increasing ghrelin. Ghrelin is a peptide that is found in the cells of the stomach. It works by binding to receptors to send a single to the brain when the stomach is empty, causing hunger.


When problems with GHRP 6 were discovered, a second generation of growth hormone releasing peptides was created, this one being called GHRP 2. What makes it different than GHRP 6 is it allows for a maximum release of GH over a longer period of time. It also has been shown to have less negative side effects than its predecessor.

It has been seen in test animals to work by stimulating the pituitary glands to release growth hormone. It works in two ways. First it works by increasing the signal to release growth hormone to increase their levels. Then it inhibits somatosatin, to also help increase the growth hormone levels.

Side Effects of GHRP

Both of these GHRPs function in similar ways and have very many similar effects:

  • Lowers body fat, while increasing lean mass
  • Increased collagen production
  • Improves circadian rhythm
  • Increases cellular repair
  • Increase in bone density
  • Increased water retention
  • Tightness in wrist/hands
  • Numbness in extremities
  • Exhaustion
  • Lower insulin sensitivity

When you compare GHRP 6 vs GHRP 2 you find that, while they do have very similar functions, GHRP 2 has the ability to maintain its maximum GH release much longer than GHRP 6. GHRP 2 also lacks the ability to increase the appetite. While much is known about these two GHRPs, there is still much to discover. These peptides are not safe to be tested on humans, and should only be used for laboratory studies.
