You’re injecting it. You should know what’s in it.

Independent lab results for peptides sold online and in clinics.

No paid placement. One published formula.

Across the whole record

57%8 of 14 certificates

fell short of at least one published limit.

The lowest-scoring vial in the record was not the compound on its label at all.

Read that certificate

Five assays decide the score.

The same panel runs on every vial. A purity number on its own tells you almost nothing — these are the five questions together.

  1. 01IdentityIs it even the compound you paid for? Purity testing cannot answer this — a vial can read 99% pure and be the wrong molecule entirely.
  2. 02PurityWhat is the rest of the powder? Truncated and incomplete sequences are the ones that can trigger an immune response.
  3. 03ContentDid you get the milligrams you paid for? A 5 mg vial at 75% net peptide content holds 3.75 mg. Every dose off that label is short.
  4. 04SterilityBacterial endotoxin causes fever, chills, and blood-pressure drops when injected. Filtering does not remove it.
  5. 05ContaminantsHeavy metals from catalysts, and industrial solvent left over from synthesis.

Every seller anyone has tested, ranked.

You buy from a seller, not from a batch. Sellers nobody has tested sit at the bottom with no score, rather than being left out.

A seller with no score has not passed. It means nobody has sent one of their vials in yet.
