Peptide education & supplies

Peptide science, without the hype.

Evidence tiers stated. Rodent data called rodent data. Dosing questions declined — here's why. COAs on every batch.

Compounds dossiered, tier stated on every one

Evidence tiers (A–D) we score every compound against

Of our compounds are rodent-data only — and we say so

Benzyl alcohol — the number that decides multi-use vs single-use water

Three things worth knowing before you read anything else here

We state the evidence tier, every time

Rodent, in vitro, small human trial, or large RCT. If the data is preclinical, we say preclinical — not "clinically studied."

We don't answer dosing questions

Not caution for its own sake — a number given to a stranger with no medical history isn't advice, it's a guess in a confident tone.

COAs on every batch

Third-party tested. Batch-matched. If a vendor won't show you a COA, that's the whole review.

How ordering actually works

No cart, no online payment — by design. Here's the whole flow.

Mechanism Explainer

GHK-Cu has actual clinical evidence behind it. Most peptides in this niche don't. But "evidence exists" and "evidence applies to how you're using it" are two different claims — and this compound is the clearest example of why that gap matters.

Handling & Storage

Bacteriostatic vs sterile water

These two vials look identical. They are not interchangeable — and the mix-up either wastes a vial or leaves you reusing something that was never meant to be reused.

Myth Correction

U-100 vs U-40 — the 2.5× error

More units marked on a barrel is not more medication. It depends entirely on which syringe you're holding.

Evidence Audit

The trial that quietly failed

AOD-9604 is still marketed hard for fat loss. It's one of the only peptides in this category that actually went through human obesity trials. What usually goes unmentioned is how those trials ended.
