Stenabolic showed up double-bagged and bubble wrapped. Nothing leaked or shifted. Took about a week.

Solid TB-500 source
Adam Cole

Ordered TB-500 for research and it came quickly. Packaging was discreet and professional. COA looked good, though I wish they included more detailed batch info. Overall happy with the purchase and would order again.

Vials were labeled properly with concentration and batch number, which makes life easier. Decent prices too.

Good experience with a few minor issues
Lisa Chang

Been using Proven Peptides for a few research compounds - specifically their GHK-Cu, CJC-1295, and MK-677. Quality seems solid based on the COAs they provide and our initial testing. My only complaint is that the website checkout process was a bit clunky and took longer than expected. Also had to reach out twice about shipping updates before getting a response. That said, the actual products arrived in good condition and appear to be exactly as described. Pricing is fair for what you're getting.
