Verified Purity
Every batch tested via HPLC/NMR to ensure ≥99% purity. Certificate of Analysis available.
Biased Agonism
Functionally selective for the G-protein pathway, decoupling analgesia from dysphoric side effects.
Non-Addictive Profile
KOR selectivity means zero interaction with mu-opioid reward pathways. A crucial tool for addiction research.

Trusted by Independent Laboratories
“Purity was exactly as stated on the CoA. The HPLC trace they provided matched what our internal QC measured to within 0.3%.”
“Order shipped within a day, packaging was discreet and intact, and the documentation made our procurement office happy.”
“Switched after a generic supplier sent us a batch that failed our purity check. SR17018 Labs has been consistent across three lots.”
