WTPWhat's That Peptide?

Stacks

Peptide stacks, decoded

You've seen the names thrown around — the Wolverine stack, the GH stack. Here's what's actually in each one, why it gets hyped, and the honest evidence grade for every peptide inside. No selling, no protocols, no dosing.

Longevity

3 peptides

Anti-Aging Stack (Epitalon + GHK-Cu + SS-31)

A biohacker "longevity" combo of three peptides — epitalon, GHK-Cu and SS-31 — each pitched at a different "hallmark of ageing". The honest picture is mixed: epitalon is Grade D, GHK-Cu Grade C, and SS-31 (elamipretide) Grade B but with major human trial failures, so nobody has shown the stack makes a person age slower.

Weight & Metabolic

7 peptides

Body Recomposition Stack (Tesamorelin + CJC/Ipamorelin + MOTS-c + BPC-157)

A clinic-and-biohacker bundle pitched to strip fat while holding onto (or building) muscle, usually growth-hormone peptides plus a metabolic peptide and a "repair" one. The mix is graded across the board: one genuinely strong member (tesamorelin), several with thin human data, and a couple resting almost entirely on animal studies.

Growth Hormone

2 peptides

CJC-1295 + Ipamorelin

The most-marketed growth-hormone peptide combo: CJC-1295 (a GHRH analogue) plus ipamorelin (a selective GHRP), run together to nudge the pituitary into releasing more growth hormone. Both are Grade C — there's some early human data on each one separately, but no proper trial of the pair, despite the clinics selling it as an anti-ageing and fat-loss certainty.

Cognition & Mood

3 peptides

Cognitive / Nootropic Stack (Semax + Selank + Dihexa)

A "brain peptide" combo marketed for focus, calm and memory: Semax for drive, Selank for anxiety, and Dihexa for synapse-building. Semax and Selank are Grade C (Russian-registered drugs with some human data); Dihexa is Grade D, with no human trials at all.

Recovery & Repair

3 peptides

Coremend (BPC-157 + TB-500 + KPV)

A ready-mixed injectable vial sold online as a healing and anti-inflammation blend: BPC-157, TB-500 and KPV. Amounts vary by seller (one lists 25mg TB-500 with 10mg each of BPC-157 and KPV, another 10mg of each). It is the Wolverine pair with KPV added. All three ingredients are Grade D, so the blend is Grade D at best.

Skin & Aesthetics

3 peptides

Cosmetic Skin Stack (GHK-Cu + Matrixyl + SNAP-8)

A topical "anti-ageing" serum combo of three skincare peptides — GHK-Cu, Matrixyl and SNAP-8 — sold for smoother, firmer, less-wrinkled skin. Unusually for peptide stacks, all three are Grade C and applied to the skin rather than injected, but most of the flattering numbers come from manufacturer-funded studies.

Cognition & Mood

4 peptides

Einstein Blend / IllumiNeuro (NA-Semax + NA-Selank + Pinealon + PE-22-28)

A ready-mixed vial sold online for focus, memory and mood, usually as "IllumiNeuro" or "the Einstein Blend": N-Acetyl Semax Amidate, N-Acetyl Selank, Pinealon and PE-22-28. Amounts vary by seller (typically 20mg NA-Semax with 10mg each of the others, though one seller lists 6mg NA-Selank). Selank is Grade C, but its small Russian human studies are of plain Selank. The other three are Grade D, so the blend is only as proven as its weakest members.

Skin & Aesthetics

2 peptides

GHK-Cu + KPV Blend

A ready-mixed injectable vial sold online for skin and inflammation, often as a "Beauty Blend": 50mg GHK-Cu with 20mg KPV in the listings we checked. GHK-Cu is Grade C, but its human evidence is for face creams, not injections. KPV is Grade D and has never been tested in people, so the blend is only as proven as its weakest member.

Skin & Aesthetics

3 peptides

GLOW 70 (GHK-Cu + BPC-157 + TB-500)

A ready-mixed injectable vial sold online as a 'glow' or beauty-and-repair blend: 50mg GHK-Cu, 10mg BPC-157 and 10mg TB-500 (70mg in total). The skin evidence belongs to GHK-Cu face creams, not injections. The other two are Grade D, so the blend is only as proven as its weakest member.

Recovery & Repair

4 peptides

KLOW 80 (GHK-Cu + BPC-157 + TB-500 + KPV)

A ready-mixed injectable vial sold online as a healing and skin blend: 50mg GHK-Cu, 10mg BPC-157, 10mg TB-500 and 10mg KPV (80mg in total). It is GLOW with KPV added. GHK-Cu is Grade C, but its human evidence is for face creams, not injections. The other three are Grade D, so the blend is only as proven as its weakest member.

Longevity

3 peptides

MitoPrime (NAD+ + MOTS-c + 5-Amino-1MQ)

A ready-mixed injectable vial sold online for energy, fat loss and ageing: 100mg NAD+, 10mg MOTS-c and 10mg 5-Amino-1MQ (120mg in total). Only MOTS-c is a peptide. NAD+ is Grade C, but its human evidence is mostly for vitamin pills that raise NAD+, not injections. MOTS-c and 5-Amino-1MQ are Grade D, so the blend is only as proven as its weakest members.

Weight & Metabolic

4 peptides

Retatrutide + Cagrilintide (GLP-1 Fat-Loss Stack)

A nickname for pairing a next-gen weight-loss injectable (retatrutide or semaglutide) with the amylin analogue cagrilintide, marketed as the "Ozempic killer" stack. The semaglutide+cagrilintide version (CagriSema) has real Phase 3 human data; the retatrutide+cagrilintide combo people actually buy on the grey market has never been tested together in humans.

Growth Hormone

2 peptides

Tesamorelin + Ipamorelin (Tesa/Ipa)

A ready-mixed injectable vial of two growth-hormone-raising peptides, sold online for fat loss and 'recomp'. Common vials hold 10mg tesamorelin with 3mg or 5mg ipamorelin. Tesamorelin is a real US medicine (Grade A), but only for deep belly fat in people with HIV. Ipamorelin is Grade C. The blend itself has never been tested.

Longevity

5 peptides

The Goddess Stack

A clinic-marketed "anti-ageing for women" bundle, usually MOTS-c, epitalon, semax, kisspeptin-10 and GHK-Cu, sold as a rotating longevity-and-hormone programme. The members run from Grade C to D, so the longevity promise rests on lab and animal work, not human proof.

Recovery & Repair

4 peptides

The Healing Stack (BPC-157 + TB-500 + KPV + GHK-Cu)

A four-peptide recovery blend sold by wellness clinics as a full-spectrum injury-repair protocol: BPC-157, TB-500, KPV and GHK-Cu. Three of the four are Grade D (animal and lab data only); even the best of the bunch, GHK-Cu, is Grade C, so the "ultimate healing" pitch runs miles ahead of the human evidence.

Recovery & Repair

2 peptides

The Wolverine Stack

A nickname for running two tissue-repair peptides together, BPC-157 and TB-500, marketed in biohacker and 'recovery' clinics for healing injuries faster. Both are Grade D: the healing story is almost entirely from animals.
