— Curated protocols
Run a stack, not just a vial.
Eight researcher-curated protocols built around overlapping mechanisms — synergy, not random combinations. Save 12–22% versus single vials, ship together, share one COA folder.

The stack library
— Build your ownOpen the builder →
Or pick three molecules and we'll quote it.
If your protocol calls for a combination not on the shelf, build it. Pick from the full library, set your dose, and we'll generate a single-COA bundle with the standard 10–18% multi-vial discount.
01
Pick 2–4 molecules. Any combination from the catalog. The builder flags receptor-overlap pairs.
02
Set dose per vial. Defaults pulled from published research; override per your protocol.
03
One ship, one COA folder. All vials from matched lots wherever stock allows. Deep links on the COA tool.

What the field is actually running.
Active-protocol counts pulled from the past 90 days of orders. The four patients reach for most often.
— Not sure where to start?
Take the protocol quiz.
Six questions about your endpoint, your study length, and your existing protocol. We'll point at one stack — or one molecule — and tell you why.
