Analytical Process
Quality & Analytical Verification
A reference material is only as reliable as the independence of the laboratory that measured it. Here is how the process works.
-
01
Sampling
A representative sample is drawn from every production batch and labelled with its batch code. The sample is never opened on our premises.
-
02
HPLC purity assay
Reverse-phase high-performance liquid chromatography establishes the main peak area. The catalogue states the measured value itself rather than a threshold claim: across the 44 published reports the median is 99.5% and the lowest value is 96.98%.
-
03
Mass spectrometry
The measured molecular mass is compared against the calculated theoretical mass. Batches outside the deviation tolerance are rejected.
-
04
Net mass confirmation
Gravimetric verification that the vial contents meet the declared mass.
-
05
Report issuance
The laboratory report is archived against its batch code and released to any researcher who requests it.

Multi-component blends report component masses instead of a single purity figure, so those reports are not in the distribution. The two lowest values belong to the same material, HGH, and are published as measured.
