The muscle & growth.

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary to produce and release growth hormone.

Ipamorelin is a selective growth hormone secretagogue that stimulates the pituitary gland to release growth hormone (GH).

Sermorelin is the shortest fully functional fragment of growth hormone-releasing hormone (GHRH), consisting of the first 29 amino acids.

MK-677 (Ibutamoren) is a non-peptide, orally active ghrelin mimetic and growth hormone secretagogue.

Tesamorelin is a synthetic GHRH analog that is FDA-approved (as Egrifta) for the treatment of HIV-associated lipodystrophy (excess abdominal fat).

GHRP-6 is the original and most well-characterized growth hormone releasing peptide, a synthetic hexapeptide that acts on the ghrelin receptor.

GHRP-2 (Pralmorelin) is a synthetic hexapeptide ghrelin receptor agonist and potent growth hormone secretagogue.

Hexarelin is one of the most potent synthetic growth hormone releasing peptides (GHRPs), producing the strongest GH release of any GHRP.

Carnosine is a naturally occurring dipeptide (beta-alanine + L-histidine) found in high concentrations in skeletal muscle and brain tissue — long-lived, high-energy-demand tissues.

MOTS-c is a mitochondrial-derived peptide (MDP) encoded within the 12S rRNA gene of mitochondrial DNA.

Kisspeptin-10 is the shortest bioactive fragment of kisspeptin, a neuropeptide that plays a central role in the initiation of puberty and regulation of the reproductive axis.

Mod GRF 1-29 (Modified Growth Hormone Releasing Factor 1-29) is a stabilized synthetic analog of endogenous GHRH with four amino acid substitutions that resist enzymatic degradation.

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a 83-amino acid recombinant analog of native IGF-1, engineered with a 13-amino acid N-terminal extension and an arginine substitution at position 3.

Follistatin-344 is the 344-amino acid isoform of follistatin, a naturally occurring glycoprotein that potently inhibits myostatin and activin A — two TGF-β superfamily members that limit muscle growth.

MGF (Mechano Growth Factor), also designated IGF-1Ec, is a splice variant of insulin-like growth factor 1 (IGF-1) produced locally in muscle tissue in response to mechanical loading and injury.

PEG-MGF (PEGylated Mechano Growth Factor) is a synthetic, polyethylene glycol-modified form of MGF, which is itself a splice variant of IGF-1 (Insulin-like Growth Factor 1) released in response to mechanical stress on muscle tissue.

IGF-1 DES (Des(1-3)IGF-1) is a naturally occurring truncated form of insulin-like growth factor-1 in which the first three N-terminal amino acids (Gly-Pro-Glu) have been removed.

Follistatin-315 is the primary circulating isoform of follistatin, a glycoprotein that binds and neutralizes members of the TGF-β superfamily, most notably myostatin (GDF-8) and activin A.

Ghrelin is a 28-amino acid acylated peptide hormone primarily secreted by oxyntic cells in the gastric fundus.

GHRH is the endogenous 44-amino acid hypothalamic peptide that drives pulsatile growth hormone secretion from the anterior pituitary.
