Avis
First order from Biosynth. It arrived quickly, but the COA appeared to have been 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. Customer service was friendly and prices are good. That documentation gap is what I'd check first next time.
First order from Biosynth. It arrived in a few days with the batch COA included. Customer service answered my documentation questions promptly, including which external lab ran the analysis. I ordered for lab reference material and I'm reporting the documentation and service side only. 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.
