Trust signals
Petratide publishes a public library with 60 product-and-strength cards and 104 batch certificates. PeptidePrices reviewed PS-R3 30mg batch PS01-R330W. The vendor-hosted ILS report lists Retatrutide identity, 99.80% HPLC purity, 31.43mg measured content, sterility no growth by PCR, endotoxin at or below 0.05 EU/mL, and elemental-impurity results. Its ILS QR verification URL returned the official ILS Laboratories record for Petratide Science and the same product, lot, date, and results. PeptidePrices also manually entered a printed Semax ILS access code in the official ILS portal and received a record match. Match the exact product, strength, and lot. A certificate does not prove that a received vial is the tested lot. Affiliate status does not affect the score.

PeptidePrices reviewed the PS-R3 30mg batch PS01-R330W. Its site report identifies ILS Laboratories as the testing laboratory. The ILS verification portal returned the official record for Petratide Science. It identifies the sample as Retatrutide and lists 99.80% HPLC purity, 31.43mg measured content, sterility no growth by PCR, endotoxin at or below 0.05 EU/mL, and elemental-impurity results. A printed Semax ILS access code was also entered into the official ILS portal and confirmed. The records are batch-specific. They do not prove that a received vial is the tested lot.
The local catalog has 28 comparison-ready rows. It maps PS-R3, PS-T2, and PS-S1 only because reviewed ILS reports identify them as Retatrutide, Tirzepatide, and Semaglutide. It excludes unsupported internal codes, liquid products, and bundles with unclear component quantities.

PeptidePrices includes that $18.95 charge in its single-order price comparisons. Its policy says sales are final. Approved damage, defect, or confirmed-loss claims can receive a replacement shipment or store credit.
Trustpilot showed a 4.3/5 exact-domain profile with 38 reviews during this audit. This is a limited and mixed reputation signal. Strong batch-level testing supports an 8.5/10 score. The young domain, small review record, and final-sale policy limit the score. Affiliate status does not affect the score.
