Good quality, shipping could be faster 2026-09-14

Ordered Growth hormone fragment from R Peptide. The COA checked out against the batch number on the vial. Shipping took about a week, slower than some suppliers. Customer service was helpful when I asked about the order status. Pricing is competitive and the paperwork was complete. This entry records a supplier-service and documentation experience. It reports no outcome and names no amount. PepsReview does not host reports of personal use of research compounds, and nothing here is a recommendation to use any product.

Best supplier I've used so far 2026-09-10

Ordered from R Peptide a couple of times. Both orders shipped quickly and the product documentation was consistent. Their COA comes from a third-party lab, which is the part worth verifying, and the certificate number matched each vial. Prices are fair for the documentation standard.

Great product but pricey 2026-09-10

R Peptide ships a batch-matched COA with the order and the certificate names the external lab that ran the analysis. Shipping was quick and the batch number on the certificate matched the vial. Pricing is on the higher side; comparing a few suppliers before committing is worth it. This entry records a supplier-service and documentation experience. It reports no outcome and names no amount.
