What researchers say
Ordered BPC-157 and TB-500, both dispatched next day from AUS, cold-packed. The purity data was on the vial, not just the website.
The lot-lookup tool sold me. Punched in my number and got the signed COA plus retention chart. That level of transparency is rare here.
GHK-Cu arrived exactly as described and reconstituted clean. Endotoxin results were on the report, no other supplier gave me that.
Subscription for my NAD+ saves the reorder hassle and a bit of cash. Packaging discreet every single time.
They actually name the auditor (Sigma Labs). Small thing, but in this space it is the difference between trust and a gamble.
