99%+ Purity on Every Batch
You See the Data Before We Ship It
What you're actually getting
We sell research-grade peptides for lab use only. Every compound exceeds 99% purity, tested by independent labs via HPLC and mass spec. Each lot is tracked from arrival through shipping. The COA and lot number on the product page match what arrives at your door.
99%+ Purity, Every Time
Not 'spot checked.' Not 'randomly sampled.' Every single lot is HPLC-tested and verified before it leaves our facility.
See The Data First
The COA is on the product page before you buy. Not hidden behind a support ticket. Not 'available upon request.'
Third-Party Verified
Independent US labs run the tests. We don't grade our own homework. Every result is from an accredited third-party facility.
Ships Same Day
Order before 2 PM PST and it goes out today. No 'processing time' padding. No warehouse delays.
