A shelf, styled for serious work.

Twelve of the most-requested compounds in our line. Every vial is lyophilized, sealed, and packed cold-chain aware. Pricing reflects current lot availability.

Our Promise

Friendly surface. Serious handling.

Three things we don't compromise on — purity, paperwork, and shipping. The friendly brand is on the outside. Inside the vial is what you're actually paying for.

01

Verified for purity.

Every lot is screened by HPLC and mass spec to 99%+ purity before it earns a label. Identity tests are run on each production batch — not periodically, not by sample. Every lot.

02

Third-party COA on every lot.

Independent lab documentation accompanies every product. Lot numbers map cleanly to test results. If something doesn't trace, it doesn't ship — full stop.

03

Same-day cold-chain shipping.

Lyophilized vials packed with thermal barriers and sensible packaging. Orders placed before 2pm CT ship the same business day. Free shipping on orders over $150.
