What happens at weeks 7-8? - Are you expecting to grow tits because if you are, "any" anti-e won't help because Deca doesn't aromatise.
Why aren't you stacking an "androgen" like test or fina with your "anabolic" (deca)? This synergistic effect is more than worth it.
Of course, IMHO, you should always take "some" test. While fina is a better androgen than test - nobody likes fina-dick, so taking some test with it prevents that. Also many are concerned that both deca and fina can cause progesterone-related gyno - again, anti-e's do nothing to prevent this. I remember Animal posting "something to the effect" that increased IGF-1 from fina was related to cause of fina-related gyno. It's debatable how much Winny competes for the progesterone receptor but it's suppose to - it's worked for me with fina and I'm VERY prone to e-related gyno.
Sorry for rambling on bro - you need to tell us more!
You haven't posted how long your cycle is but I'm guessing this is probably your first - so I hope I don't scare you out of what I'm gonna suggest. You want to switch to a fast-acting test like prop (no deca) for your last 2 weeks of the cycle. This article explains why you want to begin clomid soon as you can: http://www.professionalmuscle.com/forums/showthread.php?threadid=1172 You need to inject prop every other day (EOD) due to short ester. Just my $0.02 worth!
Clomid will help with natural test production only as far as blocking the estrogen receptor at the pituatary. That in itself
will stimluate LH/FSH (actually by reducing the suppression)- whether clomid itself has the capacity to stimluate that I dont know how that would happen, its an indirect action. Wheather clomid fits into a progesterone receptor is improbable, Winny, RU486 (hard to find) are considered progesterone blockers. So if you suffer sides from fina/deca use some winny too. Clomid likely wont help.
