A supplier that behaves like a laboratory
No inflated claims, no invented certifications. What we hold, we show; what we don't, we say.
UK supply
Stock is held and dispatched in the United Kingdom, so research orders are not waiting on international customs.
Product information
Every listing states the compound, the strength and the form supplied. Where we hold analytical documentation for a batch, it is published on that product page.
Controlled handling
Lyophilised material is held cold and dark, and packed for transit so it arrives in the condition it left in.
Discreet dispatch
Plain outer packaging with no product detail on the exterior, tracked from our bench to yours.
Method, storage and documentation
Concentration mathematics,
nothing more
Enter compound mass and total solution volume to get mg/mL and mcg/mL. It calculates concentration only — it does not produce doses or administration instructions.
