anyone know the half life of the chemical and the metabolites to show in the urine?
I have heard the detection window of GW-501516 is 40 days
really easy to detect too. stable enough to test retroactively, i'd think
EDIT: it appears this 40 days number is WRONG. I don't know where I got it from. anyway, here is the paper by Thevis et al about the detection method:
http://link.springer.com/article/10.1007/s00216-009-3283-x/fulltext.html
a quote from the conclusion: "Considering therapeutic dosages of GW1516 of 2.5 mg/day as administered, e.g., in phase IV clinical trials regarding the regulation of lipoprotein transport in metabolic syndrome [5], detection windows for the metabolites of GW1516 of up to 4 days are expected following cessation of the drug." Remark that typical dosages reported on those steroid forums are more in the order of 10s of mg per day
EDIT2: the source where I read about the 40 days is this article vy joe lindsey. "What’s more, clinical research shows that the drug is detectable as long as 40 days after a single dose.", he claims here. bicycling.com/blogs/boulderreport/2013/04/11/next-generation-drug-use-confirmed/ I would trust the 4 day number more, currently
