Two kinds of test get described as lab verification and they answer different questions. Raw material testing confirms identity and purity of the powder. Finished product testing measures the sealed vial as sold. For compounds that attract substitution, the second is the one that matters, and both are set out separately below.

Common questions
What is the difference between raw material and finished product testing?
Raw material testing confirms the powder is what it claims to be and how pure it is. Finished product testing measures the sealed vial as sold. Only the second tells you what is actually in the product, which is why it carries more weight for compounds that attract substitution.
What does a blind screen mean?
The laboratory is not told what the sample is expected to be, so identity is determined without a target to match. Janoshik screened the Masteron enanthate raw material blind and confirmed drostanolone enanthate at 98% or above.
Why do some results come in above 100% of label?
Overfill of a few percent is normal in manufacturing and means the vial contains at least the stated concentration. Results here range from 98% to 109% of label.
