I ran almost the exact same cycle, 20mg/day for 7 weeks and I didn't do
any PCT. Every single research study showed that at this low dose there
was no effect at all on the HPTA. There were also a few guys on another
board that ran before and after blood tests that showed absolutely no
effect on HPTA from Var alone. My personal experience was that it didn't
shut me down at all. On the other hand, at higher doses, which most
people do, there are reports of some people being shut down. Whether
they are true or not its hard to say, there really isn't any hard credible
data on this, all of it was anecdotal. The additional problem is that it
seems most people run other substances along with the Var so its hard
to say whether the Var shut them down or the other substance or a
combination of the 2.
A good question that I've yet to see answered is if doing an unnecessary
PCT is a bad thing. In otherwords, is there a downside of doing some
nolvadex/clomid when you had no ill effects from your cycle? If the answer
is no, then I'd think one should probably do a PCT in just as an insurance
policy.
