This application note describes the extraction of benzodiazepine compounds from whole blood, prior to GC/MS analysis. This protocol also allows the simultaneous extraction of various other drugs of abuse classes: amphetamines, barbiturates, cocaine and opiates.
ISOLUTE® SLE+ columns with 1 mL sample capacity are used to extract whole blood samples following a straightforward sample dilution. No protein precipitation or other pre-treatment is required prior to sample loading. The sample preparation procedure delivers clean extracts, good recoveries and RSD values and LLOQs from 10 ng/mL (analyte dependant).

In most cases a good Winstrol cycle will run for approximately 6-8 weeks at a dosing of 50mg every day. Some will find 50mg every other day to be all they need but as this anabolic steroid has a very short half-life, especially in tablet form daily administration is generally best. 50mg per day appears to be perfect for most any man regardless of his level of experience and we do not recommend going beyond the 8 week mark as this steroid is rather liver toxic. Winstrol is one of the more hepatic anabolic steroids we will ever use but thankfully if used responsibly the liver will return to normal values very quickly after use has been discontinued. The only exception we might make regarding the dose of a Winstrol cycle is for the competitive bodybuilder towards the very end of his contest prep cycle. Many bodybuilders find 100mg per day the last 10-14 days before a show to be very useful in-terms of really hardening them up before they step on stage; however, 14 days is the maximum recommended duration for such a dose due to the toxicity of this steroid.
