🔥 Popular Peptides

Semaglutide

99

An FDA-approved GLP-1 receptor agonist used for type 2 diabetes and chronic weight management, producing significant weight loss of 15-17% body weight in clinical trials.

GLP-1 Receptor Agonist

BPC-157

98

A 15-amino acid synthetic peptide derived from human gastric juice that promotes healing of tendons, ligaments, muscles, gut lining, and other tissues through multiple regenerative pathways.

Healing & Recovery Peptide

Tirzepatide

97

A first-in-class dual GIP/GLP-1 receptor agonist that produces up to 22.5% body weight loss, approved for type 2 diabetes and obesity management.

Dual GIP/GLP-1 Receptor Agonist

Ipamorelin

92

A highly selective growth hormone-releasing peptide (GHRP) that stimulates GH release with minimal impact on cortisol, prolactin, or appetite, making it the cleanest GHRP available.

Growth Hormone Secretagogue (GHRP)

MK-677 (Ibutamoren)

91

An orally active, non-peptide growth hormone secretagogue that mimics ghrelin to raise GH and IGF-1 levels for up to 24 hours per dose, with notable effects on sleep, appetite, and body composition.

Growth Hormone Secretagogue (Non-Peptide, Oral GHS)

CJC-1295 (no DAC) / Mod GRF 1-29

90

A modified growth hormone-releasing hormone fragment with a short half-life (~30 minutes) that stimulates pulsatile growth hormone release, closely mimicking the body's natural GH secretion pattern.

Growth Hormone Secretagogue (GHRH Analog)

TB-500

89

A synthetic version of the naturally occurring 43-amino acid peptide Thymosin Beta-4, widely used for tissue repair, wound healing, reduced inflammation, and improved flexibility.

Healing & Recovery Peptide

CJC-1295 (with DAC)

88

A long-acting growth hormone-releasing hormone (GHRH) analog with a Drug Affinity Complex that extends its half-life to 6-8 days, producing sustained elevated growth hormone and IGF-1 levels.

Growth Hormone Secretagogue (GHRH Analog)
