Growth Factors

Peptides that influence growth hormone secretion and cellular growth processes. 10 profiles.

1. Ipamorelin

   Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin levels.

2. CJC-1295

   CJC-1295 is a synthetic analog of growth hormone releasing hormone (GHRH) with a Drug Affinity Complex that extends its half-life significantly compared to native GHRH.

3. GHRP-6

   GHRP-6 is a synthetic hexapeptide that stimulates growth hormone release through the ghrelin receptor. It was one of the first growth hormone releasing peptides developed.

4. GHRP-2

   GHRP-2 is a synthetic growth hormone secretagogue that stimulates GH release through the ghrelin receptor. It is considered one of the most potent GHRPs for GH stimulation.

5. Hexarelin

   Hexarelin is a synthetic growth hormone secretagogue and one of the most potent GHRPs. It has been studied for cardioprotective effects in addition to GH release properties.

6. Sermorelin

   Sermorelin is a synthetic analog of growth hormone releasing hormone (GHRH) containing the first 29 amino acids, which represent the active portion of the natural hormone.

7. Follistatin 344

   Follistatin 344 is a naturally occurring glycoprotein that functions as a potent inhibitor of myostatin, activin, and other members of the TGF-beta superfamily. It has been extensively studied for its role in promoting skeletal muscle growth and as a gene therapy candidate for muscular dystrophy.

8. IGF-1 LR3

   IGF-1 LR3 is a modified form of insulin-like growth factor-1 with an arginine substitution at position 3 and a 13-amino acid N-terminal extension, designed to have reduced binding to IGF-binding proteins, which increases its free, biologically active fraction and potency.

9. MK-677 (Ibutamoren)

   MK-677 (ibutamoren) is an orally active, non-peptide small molecule agonist of the ghrelin receptor (GHSR-1a) that stimulates endogenous growth hormone and IGF-1 secretion, studied in randomized trials in older adults, obesity, and sleep research.

10. Mod GRF 1-29

    Mod GRF 1-29 is a tetrasubstituted analog of GRF(1-29), the shortest fully active fragment of growth hormone-releasing hormone, engineered for enzymatic stability; it is identical to the peptide core of CJC-1295 but lacks the Drug Affinity Complex (DAC) albumin-binding linker.
