| Laboratory | Who they are | Methods used |
|---|---|---|
| Analiza Bialek | A Polish analytical laboratory widely used for anabolic compound testing. | HPLC, with infrared spectroscopy for identity confirmation on raw material. |
| Janoshik | A Czech analytical laboratory known for blind screening, where the lab is not told what the sample is expected to be. | Blind screen. Identity and purity are determined without a stated target. |
What a blind screen adds
In a standard assay the laboratory is told what compound to look for and reports how much of it is present. In a blind screen it is not told, so identity has to be established rather than confirmed. That is a stronger test of identity, and it is why the Janoshik screen on the Masteron enanthate raw material is worth more than a fourth confirmatory assay would have been.
HPLC and infrared
High performance liquid chromatography separates a sample into its components and quantifies each, which is what produces a content figure in mg per ml. Infrared spectroscopy is used alongside it on raw material to confirm identity, because two compounds can behave similarly on a chromatogram while differing structurally.
Common questions
Who are Analiza Bialek?
A Polish analytical laboratory widely used for anabolic compound testing. They carried out the finished product assays and the raw material HPLC work on these preparations.
Who are Janoshik?
A Czech analytical laboratory known for blind screening. They screened the Masteron enanthate raw material without being told what it was expected to be, and confirmed drostanolone enanthate at 98% or above.
Why does testing by two laboratories matter?
Because agreement between independent laboratories is harder to arrange than a single favourable result. The Masteron enanthate raw material was confirmed at 98% by both.
