Independent HPLC (Janoshik Analytical) Testing Summary – 2025

The attached document is a summary of 2025 HPLC analytical results of oil-based anabolic steroids (I've left out orals, peptides and HGH at this stage). Samples were sent into Janoshik Analytical for identification and quantitative analysis by members of the online communities Evolutionary.org and UGLtalk.is (thankyou especially to @Ratatata and @Bluebone for letting me harass them for links to their independent testing). Apologies if I missed anyone else's that they've sent in - DM me if you have a result that I have not included.

34 samples were included and the full results are available in Table 1 of the document. A margin for error threshold of 10% was applied for dosing accuracy.

Of the 34 samples, all 34 contained what was expected. With respect to dosage, 2 samples were underdosed (84% and 89%), 29 samples were the correct dosage, and 3 samples were overdosed (111%, 119% and 110%).

The results highlight two things:

1) The overall high quality of verified vendors in the two communities.

2) That Janoshik analysis is still the gold standard for testing. Transparent methodology, standardised and precise.

Stay safe legends 💪
