I’ve done my research on Androsol and drug testing, but can’t find anything on hair follicle testing. Does andro show up in hair follicles, as marijuana or other drugs would?

Both testosterone and 4-AD are naturally present in the body in large amounts. Androsol does increase 4-AD levels by about 4 times relative to normal, so potentially the hair might have clearly more 4-AD in it; but 4-AD testing is not something anyone is doing right now, except by developing a special assay on specific request, as we had to have done.
