Injury recovery & tissue repair
“Healing” peptides are among the most-hyped in the space. The biology is genuinely interesting, but for most of these the controlled human evidence is thin and the compounds are unapproved and gray-market. Here is what each is actually supported to do.
The repair peptides
BPC-157, TB-500, and their newer stand-ins — the core of the recovery category.
BPC 157: what the evidence actually shows (and what it doesn't)
The 'healing peptide' has a deep rodent literature and almost no human data. A straight read of where the science stands.
TB-500 and thymosin beta-4: separating the trials from the hype
Real Phase 2 dry-eye data, deep preclinical neuro/cardiac work, and a recovery-market use that was never actually tested.
The BPC-157 + TB-500 blend (“Wolverine stack”): popular, but proven?
The combined recovery protocol has a tidy mechanistic story and zero combination trials. A straight read of what the blend is, the theory, and the gaps.
BPC-157 vs TB-500: the recovery peptide pair, graded on evidence
They're sold as a matched 'healing stack,' but BPC-157 and TB-500 are unrelated molecules with different mechanisms — and the same honest ceiling: overwhelmingly preclinical for recovery, with no human randomized trials.
Pentadeca Arginate (PDA): the evidence behind the BPC 157 successor
PDA is marketed as a more stable upgrade on BPC 157 — but it has almost no research of its own. A straight read of a borrowed evidence base.
Joints, tendons & skin
Targeted recovery — connective tissue, cartilage, and skin repair.
Peptides for joint pain: what the human evidence actually shows
BPC-157, TB-500 and copper peptides are marketed for cartilage, tendon and ligament repair. Graded by real human evidence, the joint-pain ladder is nearly empty at the top.
How to Heal Tendons Faster: What the Evidence Supports
Loading beats injections beats peptides: a straight, evidence-ranked guide to what actually helps a tendon recover — and what is just hype.
GHK-Cu: the copper peptide between real skincare and overclaim
A decades-deep molecule with a credible topical story — and systemic anti-aging claims that outrun the human data.
Gut & immune repair
The gut-lining and immune-modulating peptides used in recovery protocols.
Larazotide: the leaky-gut peptide that failed its Phase 3 trial
An 8-amino-acid tight-junction regulator with real celiac data and a failed pivotal trial — and why the supplement use runs far ahead of the evidence.
KPV peptide: what the evidence actually shows (benefits, dosage talk, and side effects)
KPV is the anti-inflammatory tripeptide tail of α-MSH, sold for gut, inflammation, wound-healing and skin. The mechanism is real and the mouse data are real — but there are essentially no human trials. A straight read of where the science stands.
Thymosin alpha-1 (Tα1): a real immune drug abroad, read against the wellness pitch
Tα1 (brand Zadaxin) is an approved immunomodulator in dozens of countries — for hepatitis, sepsis and severe infection, supervised. It is not FDA-approved, not the same as TB-500, and not the general anti-aging injectable sold online. The honest evidence, dosing and side-effect read.
ARA-290 (cibinetide): the EPO-derived repair peptide and what its trials actually show
An 11-amino-acid peptide engineered from erythropoietin to protect tissue without making red cells. A straight read of the small-fiber-neuropathy evidence — and its limits.
