My first time on PCT. Got Nolva.
12weeks on 400mg Test-E.
2weeks on Dbol.
8days after last injection ok to start?
Why is it considered not good to use Nolva too early?
No. Half life is about a week so you’ll still have plenty of Test E in your system after 8 days. You need to wait closer to clearance which is 3-4 weeks depending on your source for the half life info.
Great! So the whole idea is to get rid of the E after test is out of your system? Why is it considered a waste to suppress E while the rest is still there?
Half life info is pretty all over the place from what I’ve seen trying to find an answer. I see a lot of sources saying 4.5 days roughly. I posted because that difference will be a noteworthy difference if waiting a certain amount of half lives to start PCT.
I’d say 3 weeks is more than enough with Test E, unless someone was running a very high dose (which isn’t the case here). 4 weeks would be overkill here IMO. I’d lean more towards 2-2.5 week wait period based on the relatively low dose of 400 mg/wk.
Thanks! But can someone explain why you wait for half-lives? Does it effect the potency of a PCT?
You won’t convince your body to start producing testosterone when you already have it in your system exogenously. You need for it to be mostly clear as stated. Depending on your source the window I stated is correct albeit I agree with @mnben87 that the earlier onset is likely effective.

This is a good answer. I’d recommend you wait until you are at least in the ball park of Low T.
You have a steady state (or near it level at the end of the cycle of 400 mg/wk), after 1 half life you are effectively on 200 mg/wk (which is still too much for your body’s systems to want to start making Test on it’s own again), after 2 half lives, you are effectively on 100 mg/wk (probably still too much). After 3 half lives (roughly 15 days), 50 mg/wk, which is definitely getting close, and perhaps enough has cleared, and if not, it will be low enough in a matter of days (you wouldn’t be wasting much of your PCT time).
I’d say wait 3-4 half lives based on your cycle dose of 400 mg/wk. I’d say more like 5-6 half lives if you were using 2,000 mg/wk. I’d just wait at least 2 weeks based on a roughly 5 day half life it was me.
Thank you both !
I now have a better understanding of the “mechanics” at work, it makes logical sense.
Still feeling on top at the gym, so guess my T levels are still good. Called my doctor for some blood work, she grasped and told me to see someone else, she didn’t like the idea of helping me run a bulking cycle. 
Again, thanks!
