So this will be my 3rd go on the geartrain .. and I am wanting to give tren ace a go.. that being said I was thinking of running it relatively short (6 weeks) and then finishing off with 10 or so weeks of primo .. obviously with test as a base and going to run it appropriately but I was curious if that is legit to do, or if I would need to give the tren sometime to clear out first, or not do that at all or what ? Apologies if this a a rookie ass question (refer to username)
