Are there independent labs that can verify the purity and potency of my prescriptions?

[QUOTE="madman, post: 143571, member: 13851"] Not aware of any labs that would do such.....and if anything I could see one being doubtful of UGL or possibly compounded products but big pharma (highly doubtful). Unfortunately the testings kits will only tell you if it contains the steroid you are testing for or a completely different steroid or no steroid at all but will not tell you the potency/strength if a steroid is present. In order to properly test for steroid/potency/purity one would need to have that done at a laboratory: The reported methodologies generally include [B]some sort of sample treatment of extraction before the analytical step,[/B] which always includes [B][COLOR=rgb(184, 49, 47)]a separation by liquid or gas chromatography (LC) [/COLOR]coupled to mass spectrometry (MS) or tandem mass spectrometry (MS/MS). [/B] [B]A simple toxicological analysis of anabolic steroid preparations from the black market [/B] [B]Abstract [/B] [B][COLOR=rgb(184, 49, 47)]Objectives:[/COLOR][/B] A [B]simple[/B] and [B]rapid [COLOR=rgb(184, 49, 47)]gas chromatography (GC) method with mass spectrometry (MS)[/COLOR] detection was developed for the identification and quantification of anabolic steroids in pharmaceutical preparations from the black market[/B]. [B][COLOR=rgb(184, 49, 47)]Material and Methods: [/COLOR][/B]After a liquid-liquid extraction of pharmaceutical products at acidic, neutral and basic pH with chloroform-isopropanol (9:1, v/v), the different steroids were separated by fused silica capillary column and detected by electron impact (EI)-MS in positive ionization mode. [B][COLOR=rgb(184, 49, 47)]Results and Conclusion:[/COLOR][/B] The assay was validated in the range from 10 mg to 250 mg/g powder preparations and 0.02 mg to 200 mg/mL liquid preparations with good determination coefficients (r2 0.99) for the calibration curves. At three concentrations spanning the linear dynamic ranges of the calibration curves, mean recoveries were always higher than 90% and intra-assay and inter-assay precision and accuracy were always better than 15%. This method was successfully applied to the analysis of 15 pharmaceutical preparations sold by illegal sources. [B]In only [COLOR=rgb(184, 49, 47)]two cases[/COLOR] the content was the one reported on the labels. In the other cases, [COLOR=rgb(184, 49, 47)]no substances at all[/COLOR], or [COLOR=rgb(184, 49, 47)]steroids different [/COLOR][/B][COLOR=rgb(0, 0, 0)][B]from those reported on the labels[/B][/COLOR][B] or [COLOR=rgb(184, 49, 47)]different amounts[/COLOR] from those declared were found.
