S1Research

First order from S1Research. It arrived quickly, but the COA appeared to be produced in-house rather than by an independent lab, and no external testing lab was named. I couldn't confirm the batch against an external certificate, so I asked about it. That documentation gap is what I'd check before ordering again. 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.

S1Research 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.
