Customer Reviews

Katarzyna W. — ★★★★★
Third order in six months. Every vial identical to the last — same clarity after reconstitution, same dissolution time, no particulates. Peptex consistency is what keeps me coming back.

Sven L. — ★★★★★
Vial arrived double-insulated with cold packs still cold after 5 days to Sweden. Powder reconstituted in under 3 minutes with bacteriostatic water. CoA matches what is listed on the website — HPLC 99.1%.

Petra M. — ★★★★
Shipping to Czech Republic was 7 days which felt slow, but the product was in perfect condition on arrival — seals intact, powder dry, no clumping. Quality is 5 stars, logistics 3.5.

Tried two other EU sources before Peptex. This is the only one where the CoA is traceable and the batch number is printed on the vial cap. Small detail, big trust signal.

Thomas H. — ★★★★★
Reconstitution is straightforward — added BAC water slowly along the vial wall, swirled gently, fully dissolved in 90 seconds. No yellow tint, no cloudiness. Exactly as described.
