Just wondering if you could fail an IOC drug test from using MAG-10?
Neither 4-AD nor Androst-1-ene are prohibited
substances, so I think not, provided your
epitestosterone levels are reasonable.
In other words, after a MAG-10 cycle once
you've recovered natural T (and epi-T)
production you should be fine. During the
cycle, since your epi-T would be very low
yet you'd have normal T from conversion
of 4-AD, I'd suppose you could fail the
