The safest and most well-studied peptides for new researchers - BPC-157, ipamorelin, and beginner-friendly protocols.
A pentadecapeptide derived from human gastric juice that promotes wound healing and tissue repair. Demonstrates remarkable regenerative properties across multiple tissue types including tendon, muscle
Dose: 250-500 mcg per dose | Route: Subcutaneous injection (or oral capsules)
A highly selective GH secretagogue that stimulates GH release without significantly affecting cortisol, prolactin, or ACTH. Considered the cleanest GHRP.
Dose: 100-300 mcg | Route: Subcutaneous injection
A synthetic version of thymosin beta-4, a naturally occurring 43-amino acid peptide that promotes cell migration, blood vessel growth, and reduces inflammation. Widely researched for tissue repair and
Dose: 2-5 mg per dose | Route: Subcutaneous injection
A naturally occurring copper-binding tripeptide that declines with age. Promotes collagen synthesis, wound healing, and has broad regenerative effects on skin, hair follicles, and tissues.
Dose: 1-3 mg topical ยท 200-500 mcg injectable | Route: Topical cream/serum or subcutaneous injection
A synthetic GHRH analog with 4 amino acid substitutions for stability. Often combined with DAC for extended half-life or used without DAC for pulsatile release.
Dose: 100-300 mcg | Route: Subcutaneous injection
A semi-synthetic polysulfated xylan with anticoagulant and fibrinolytic properties. FDA-approved for interstitial cystitis, also researched for osteoarthritis and cartilage repair.
Dose: 100 mg | Route: Oral or subcutaneous injection
