Safety & Side EffectsThe anchor safety guide to the peptide class — separating what the molecule does from what is actually in the vial, with the load-bearing contraindications, interactions, injection risks, and the shifting 2026 FDA/WADA landscape.

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.

The ScienceA clinical explainer separating true peptides from the SARMs, small-molecule drugs, hormones, and supplements sold beside them on the same gray-market storefronts. Chemistry, evidence, FDA status, and anti-doping rules are all class-specific.

Safety & Side EffectsA single, evidence-graded map of what the published literature actually shows for the peptide field — separating the handful of Grade-A, FDA-approved peptides from the much larger group whose claims rest on animal data, mechanism, or marketing alone.

Injuries & OrthopedicsWound healing is one of the few peptide areas with genuine human controlled-trial data — but it is narrow, topical, and concentrated in chronic wounds. A clinical-editorial ranking of GHK-Cu, thymosin β4, LL-37 and BPC-157 by what the evidence actually supports in 2026.

Legal & Regulatory"Legal" is not one question but five — FDA approval, compounding eligibility, DEA scheduling, WADA sport status, and state telehealth law. A date-stamped 2026 explainer of where peptides actually stand.

Injuries & OrthopedicsAn evidence-graded review of the peptides marketed for wrist sprains, tenosynovitis, TFCC tears and carpal tunnel syndrome. The honest 2026 verdict: no human RCT — indeed essentially no human data of any kind — exists; the case is entirely preclinical (rat tendon and sciatic-nerve models), and conventional care has the far stronger human evidence.

Injuries & OrthopedicsA clinical, evidence-first ranking of the peptides most promoted for healing surgical incisions and preventing scars — separating genuine human topical-wound data from animal-only signals and marketing.

Sexual & Hormonal HealthThe peptides with real human evidence for raising or protecting endogenous testosterone are the classical reproductive gonadotropins — hCG and LH/FSH — not the boutique 'natural testosterone' research peptides. A ranked, evidence-graded review for 2026.

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 & OrthopedicsAn evidence-graded look at the peptides marketed for rotator-cuff tears and repair recovery — BPC-157, TB-500/Thymosin β4 and GHK-Cu — separating a single unpublished rat abstract and animal mechanism from anything resembling human proof.

Injuries & OrthopedicsAn evidence-graded review of the peptides marketed for osteoarthritis and joint degeneration. The honest 2026 verdict: the strongest human data belongs not to any joint-repair peptide but to GLP-1 metabolic drugs that relieve knee-OA pain by removing mechanical load.

Energy, Cognition & MoodA clinical, evidence-graded ranking of the peptides marketed for neuroprotection — Cerebrolysin, Semax, ARA-290, SS-31/elamipretide and P021 — separating a modest, mixed human signal from elegant but preclinical-only mechanism.

Injuries & OrthopedicsAn evidence-graded review of the peptides marketed for whiplash and neck soft-tissue injury. The honest 2026 verdict: there is no human evidence — no RCT, cohort, or registered trial — for any peptide in the cervical spine; the strongest case tops out at rat ligament and tendon models.

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 & OrthopedicsAn evidence-graded review of the peptides marketed for muscle growth and lean mass — follistatin, CJC-1295, ipamorelin, MGF and IGF-1 LR3. The honest 2026 verdict: no peptide has Grade A human muscle-outcome data, and every one is prohibited in sport by WADA.
