Growth hormone secretagogues and related peptides have been studied for their effects on lean mass, recovery speed, and metabolic function. The peptide research pages below are educational resources — they do not constitute medical advice or treatment recommendations.
NNC 26-0161
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It stimulates pulsatile GH release from the anterior pituitary with high selectivity — producing minimal effect on cortisol, prolactin, or ACTH compared to earlier GHRPs. It is commonly researched for its role in supporting body composition, recovery, and lean mass maintenance.
GHRH 1-29, Sermorelin Acetate, Geref
Sermorelin is a GHRH analogue used to stimulate endogenous growth hormone production. It is one of the most widely prescribed peptides in the anti-aging and functional medicine space, valued for preserving the natural pituitary feedback axis while supporting body composition, sleep quality, and tissue repair. Compounded formulations are available in the US through 503A pharmacies.
ACVR2B-Fc, Ramatercept
A soluble decoy receptor that blocks the ActRIIB pathway, inhibiting myostatin and related TGF-β family proteins. Produces dramatic muscle and bone gains but carries cardiovascular risks at high doses.
Beta-alanyl-L-histidine, L-Carnosine
A naturally occurring dipeptide in muscle and brain tissue with multiple anti-aging and performance benefits. Buffers muscle acidity during exercise and prevents glycation-related aging damage.
FST-344, Follistatin
A myostatin inhibitor that removes the natural limit on muscle growth. Produces dramatic increases in muscle mass and strength by blocking TGF-β family proteins.
Growth Hormone Releasing Peptide 2, Pralmorelin, GHRP2
GHRP-2 is a synthetic growth hormone secretagogue that triggers natural GH release from the pituitary gland. It is commonly used alongside GHRH analogs to support muscle growth, fat loss, and recovery. For educational purposes only — consult a qualified healthcare provider.
Growth Hormone Releasing Peptide-6
A hexapeptide that strongly stimulates growth hormone release while also increasing appetite. Commonly used for muscle gain and recovery.
Examorelin, EP-23905
The most potent synthetic GHRP, stimulating significant GH release. Also has direct cardioprotective properties independent of GH.
Insulin-like Growth Factor 1 Long R3, Long R3 IGF-1, IGF1 LR3
IGF-1 LR3 is a synthetic, long-acting analog of insulin-like growth factor 1 used in research and clinical contexts for its potent anabolic and recovery-promoting effects. It stimulates muscle protein synthesis, supports fat metabolism, and may enhance recovery from injury. For educational purposes only — consult a qualified healthcare provider.
Insulin-like Growth Factor 2, IGF-II
The second insulin-like growth factor, with anabolic effects on muscle and metabolism. Has a different receptor binding profile than IGF-1, potentially with a more favorable safety margin.
Mechano Growth Factor, IGF-1Ec
A splice variant of IGF-1 produced in response to mechanical stress. Activates muscle satellite cells locally for repair and growth at the site of damage.
Ibutamoren, MK-0677, Nutrobal
MK-677 (Ibutamoren) is an orally active, non-peptide ghrelin receptor agonist and growth hormone secretagogue. Unlike injectable GH peptides, it is taken orally and provides sustained elevation of GH and IGF-1 levels throughout the day. It is commonly researched for muscle and body composition outcomes, and is of particular interest for users who prefer oral administration routes.
CJC-1295 no DAC, Modified GRF 1-29, Tetrasubstituted GRF 1-29
A stabilized GHRH analog that amplifies natural GH pulses. Most effective when combined with a GHRP (e.g., Ipamorelin or GHRP-6) for synergistic GH release.
GDF-8 propeptide, Myostatin inhibitor propeptide
The body's own myostatin inhibitor. By supplementing the propeptide, myostatin suppression is extended, allowing greater muscle growth. More physiological alternative to Follistatin 344.
