Performance Peptides

IPA

Ipamorelin is a selective growth hormone secretagogue that stimulates the pituitary gland to release growth hormone. It is considered one of the mildest GHRPs with fewer side effects than alternatives like GHRP-6.

CJC-1295 (no DAC)

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates sustained growth hormone secretion. The no-DAC (Drug Affinity Complex) version provides pulsatile GH release that more closely mimics natural physiology.

Geref

Sermorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) consisting of the first 29 amino acids of GHRH. It was previously FDA-approved for diagnosing and treating pediatric GH deficiency and is now widely used in anti-aging medicine.

Egrifta

Tesamorelin is an FDA-approved synthetic analog of GHRH used to reduce excess abdominal fat in HIV-associated lipodystrophy. It is the only GHRH analog with current FDA approval and is increasingly used off-label in anti-aging and metabolic health contexts.

Growth Hormone Releasing Peptide-2

GHRP-2 is a synthetic hexapeptide growth hormone secretagogue that stimulates the pituitary gland to release growth hormone. It is considered one of the most potent GHRPs available and is used as a GH stimulation test diagnostic in some countries.

Growth Hormone Releasing Peptide-6

GHRP-6 is a synthetic hexapeptide growth hormone secretagogue known for its strong GH-releasing effects and pronounced appetite stimulation. It was one of the first GHRPs developed and is widely used in research and performance contexts.

PEGylated Mechano Growth Factor

PEG-MGF is the PEGylated form of Mechano Growth Factor, a splice variant of IGF-1 that is expressed in response to mechanical stress on muscle tissue. PEGylation extends its half-life, making it practical for research and performance applications focused on muscle repair.

Ibutamoren

MK-677 (ibutamoren) is an orally active, non-peptide growth hormone secretagogue that mimics ghrelin's action. Despite not being a peptide, it is commonly tracked alongside GH-releasing peptides due to its similar mechanism and use case. It elevates GH and IGF-1 levels without affecting cortisol.

Testolone

RAD-140 (testolone) is a selective androgen receptor modulator (SARM) that binds to androgen receptors with high affinity and selectivity. While not a peptide, it is commonly tracked in the peptide community due to overlapping use cases. It is studied for muscle wasting and breast cancer.

Long R3 IGF-1

IGF-1 LR3 is a modified form of insulin-like growth factor-1 with an extended half-life due to a 13-amino acid N-terminal extension and an arginine substitution at position 3. It is studied for its potent anabolic effects on skeletal muscle, including hyperplasia (new muscle fiber formation).

SLUPP332

SLU-PP-332 is a small-molecule agonist of estrogen-related receptor alpha (ERRalpha) studied as an exercise mimetic for its ability to activate transcriptional programs associated with aerobic exercise adaptation, including mitochondrial biogenesis and muscle fiber-type switching.

FS-344

Follistatin 344 is a recombinant form of the naturally occurring glycoprotein that potently inhibits activin and myostatin signaling. Studied in gene therapy and protein-based research models for muscle growth regulation and fibrosis pathways.

ACVR2B-Fc

ACE-031 is a soluble fusion protein of the ActRIIB extracellular domain and human IgG1 Fc. It functions as a decoy receptor sequestering myostatin, activin, and other TGF-beta ligands to promote muscle growth.
