Compound Notes

Blend vials: how component ratios are set and verified

A blend is only as trustworthy as the single compounds that went into it, and the weighing step in between.

20 May 2026 · 3 min read

Single compounds first

Every component of a blend is released as a single compound first, with its own identity and purity results, before it is eligible to enter a blend run.

Weighing and homogeneity

Components are weighed on a calibrated analytical balance and combined in solution before lyophilisation, which produces a far more homogeneous result than dry blending. A sample from each run is re-tested post-lyophilisation.

Reading the label

Our blend labels state each component and its individual milligram contribution — for example, KLOW 80mg lists BPC-157 10mg, TB-500 10mg, GHK-Cu 50mg and KPV 10mg. If a blend label states only a total, you cannot calculate anything from it.
