Peptide Library Reference notes on 16 common peptides — benefits, side effects, typical dosing and how they're administered.
All GH secretagogue Healing & recovery Longevity & energy Metabolic / GLP-1 Metabolic / fat loss Nootropic Skin, hair & anti-aging
BPC-157 Healing & recovery
Synthetic pentadecapeptide derived from a gastric protein, used for soft-tissue and gut repair.
Synthetic fragment of Thymosin Beta-4 that promotes cell migration and tissue remodeling.
Ipamorelin GH secretagogue
Selective growth hormone secretagogue with minimal impact on cortisol or appetite.
GHRH analog that raises baseline GH and IGF-1; DAC version has a much longer half-life.
GHK-Cu Skin, hair & anti-aging
Copper-binding tripeptide known for collagen synthesis, skin remodeling and hair support.
Russian-developed nootropic peptide affecting BDNF and dopamine signalling.
Anxiolytic peptide analog of tuftsin, often used alongside Semax.
Tirzepatide Metabolic / GLP-1
Dual GIP and GLP-1 receptor agonist for blood sugar control and weight loss.
Semaglutide Metabolic / GLP-1
GLP-1 receptor agonist widely used for type 2 diabetes and weight management.
AOD-9604 Metabolic / fat loss
Modified fragment of human growth hormone targeting fat metabolism without GH effects.
Coenzyme central to mitochondrial energy production and DNA repair; declines with age.
Epithalon Longevity & energy
Tetrapeptide studied for telomerase activation and pineal/circadian regulation.
Retatrutide Metabolic / GLP-1
Investigational triple agonist of GLP-1, GIP and glucagon receptors targeting large weight reductions.
Tesamorelin GH secretagogue
GHRH analog approved for reducing visceral adipose tissue, with strong IGF-1 elevation.
Mitochondrial-derived peptide studied for metabolic regulation, exercise capacity and insulin sensitivity.
Anti-inflammatory tripeptide fragment of α-MSH used for gut and skin inflammation.
