Peptide vendor warning
Community Warning!
An independent vendor reviewer (VialVerdict) states HPLC testing and third-party COAs are "available on request only" and "not standard practice", directly contradicting the vendor's own claim of publicly available, per-batch, QR-linked COAs. Independent lab aggregator Finnrick.com has tested only 5 samples covering a single product (Retatrutide), with 1 of 5 failing purity/fill standards. The vendor's official social media presence (Instagram ~36 followers, Facebook ~28 likes) is unusually small for a company claiming 1,500+ Trustpilot reviews. Peptide returns are not accepted at all, and non-peptide returns incur a 15% restocking fee.
