Peptide reference library

This is a research peptide reference library written in plain language. Each page covers what a compound is and where it stands with regulators, and the interactive library on the homepage holds the fuller reference detail for every compound. PepCaddie does not sell peptides and does not choose a dose for anyone.

• BPC-157 guide

  A plain-language BPC-157 guide: what the peptide is, where it stands with regulators, and how to read the claims made about it. Reference information only.

• TB-500 guide

  TB-500 is not thymosin beta-4, and the trials cited for it studied the other molecule. What those trials found, and what exists for TB-500 itself.

• KPV guide

  Nobody has published giving KPV to a human. FDA searched and said so in 2026. What the mouse, rabbit and cell studies found, and why no reports is not safety.

• Ipamorelin guide

  Ipamorelin is an abandoned drug programme, not an untested one. Its phase 2 trial missed its endpoint, and FDA advisers voted 0 to 12 against it in 2024.

• Tesamorelin guide

  Tesamorelin is approved for one narrow use in HIV-associated lipodystrophy, and its label says it is not for weight loss. What the trials actually found.

• MOTS-c guide

  No published study has given synthetic MOTS-c to a human. Human studies measure the peptide people already make or a gene variant. What that actually shows.

• NAD+ guide

  An NAD+ drip and an NAD+ capsule are not the same subject. A 2026 review found no outcomes trial of infused NAD+ at all. What the oral trials actually found.

• Retatrutide guide

  What the published retatrutide trials actually found, why its phase 3 obesity results are still unreported, and what remains unknown. Investigational only.

• Tirzepatide guide

  What the tirzepatide trials found, what its approved labels cover, and why compounded versions are a different question. An approved medicine, reported plainly.

• GHK-Cu guide

  GHK-Cu is a lawful cosmetic ingredient and an unapproved injectable. What the controlled skin trials found, and why no human trial of the injected form exists.

• Glow Blend guide

  Glow Blend is BPC-157, TB-500 and GHK-Cu in one vial. No study of the combination exists, and the one animal test of two components found no added benefit.

• KLOW Blend guide

  KLOW Blend is Glow Blend plus KPV. What the fourth peptide adds in evidence is nothing: no human study, no pharmacokinetics and no toxicology in any species.

• Melanotan II guide

  Melanotan II is not melanotan I and not bremelanotide. The whole human tanning evidence is three volunteers, and the reported harms are far better documented.
