cool, a car anology
you dont run your engine for a long time and you try to restart it in the middle of winter what happens?
nah, that one sucked. nevermind LOL
your testes are not shut down your BRAIN is shutdown from extra hormone.
hcg is an exogenous LH so your testes dont care where LH signal is coming from it will be ON during hcg administration. However your brain is down from exo test and exo LH, ehhh no matter thats what the true PCT is for when all the hormones are out and your endo LH is boosted.
now the argument is that your nuts are dormant from the lack of LH so waking up the slumbering raisins will be harder than already full nuts that are tuned to receiving LH. and your brain will sense low steroids when you are completly off and start LH production and your nuts will sensitively respond.
BUT
there are tons of people swear hcg for the end so im not trying to attack you here just saying the obvious argument of the other side.
i am doing a 6 month cycle low dose test and running hcg throughout, next year i will do the same maybe without hcg depending on how i recover this time.
as for the topic starter, wait 2-3 weeks after your last shot of test then do your PCT whatever you have in mind. thats the best way to start PCT IMO for test only cycle. i like test only cycle too.
