Guides & Peptides 101What peptides actually are, how they differ from drugs, hormones and supplements, the major functional classes, and — crucially — what the human evidence does and doesn't support, from Grade-A medicines to Grade C-D research peptides.

Injuries & OrthopedicsTendon is the single best-studied musculoskeletal target for repair peptides — yet no human RCT exists for any peptide in any tendinopathy. We rank BPC-157, TB-500/thymosin β-4 and GHK-Cu strictly by the real evidence.

Injuries & OrthopedicsA clinical, evidence-first look at the peptides pitched for rotator-cuff tears, labral injury and shoulder tendinopathy — BPC-157, TB-500/thymosin β-4, and GHK-Cu — and why all three are graded C (preclinical only) for the shoulder.

Injuries & OrthopedicsA clinical, evidence-graded review of the peptides marketed for hamstring pulls, calf and quad strains, and muscle tears — where the animal data are genuinely muscle-specific, and why no completed human trial yet proves any of them heals a strain.

Injuries & OrthopedicsA clinical, evidence-graded review of the peptides marketed for sprains, MCL tears and ACL injury — where the rat data are genuinely ligament-specific, and why no human trial yet proves any of them heals a torn ligament.

Injuries & OrthopedicsA clinical, evidence-first look at the peptides pitched for lateral and medial epicondylitis — BPC-157 and TB-500/thymosin β-4 — and why both are graded C (preclinical only) for the elbow.

Injuries & OrthopedicsA clinical, evidence-ranked look at the peptides marketed for back injury, spinal soft-tissue repair, and disc health — what the published data actually supports, and what is marketing.

Injuries & OrthopedicsAn evidence-graded review of the peptides marketed for athletic recovery — BPC-157, ipamorelin, CJC-1295 and TB-500. The honest 2026 verdict: every one is Grade C or D for recovery as an outcome, none is FDA-approved, and all are WADA-banned at all times.

Peptide EncyclopediaA clinical monograph on Thymosin Beta-4 (Tβ4) — the actin-sequestering repair peptide with a real, decades-long human-trial record in ocular, dermal and cardiac repair. Grade B human evidence, no FDA-approved product, and an unsettled 2026 legal status.

Peptide EncyclopediaA clinical monograph on Ac-SDKP (goralatide/seraspenide), the N-terminal tetrapeptide fragment of thymosin beta-4. Human chemoprotection data (Grade B), preclinical-only anti-fibrosis, and a WADA-prohibited 2026 status.

Peptide EncyclopediaA clinical monograph on TB-500 — the synthetic thymosin β4 fragment (Ac-LKKTETQ) marketed for tendon, muscle and tissue repair. Strong preclinical biology, no human efficacy RCT of the fragment, and an unsettled 2026 legal status.

Peptide EncyclopediaA clinical monograph on Pentadeca Arginate (PDA) — the L-arginine salt of BPC-157 marketed for tendon, gut and wound healing. Zero PDA-specific studies, borrowed preclinical data, and an unsettled 2026 legal status.

Peptide EncyclopediaA clinical monograph on Pentadeca Arginate — the L-arginine salt of BPC-157. No studies exist under the 'PDA' name; the borrowed parent evidence is 35:1 preclinical, with zero human RCTs and an unsettled 2026 legal status.

Peptide EncyclopediaA clinical monograph on the arginate (di-L-arginine) salt of BPC-157 — the same peptide with an arginine counterion. The storage and gastric-acid stability advantage is real; the headline oral-bioavailability claims are unproven marketing.
