Add HCG 300 mcg, 2x/week when your on and your boys will stay protected =)
AAS can acts like a mild birth control for men. Your boys wont drop to zero even when you are on, which is why some people can still get prego when they are on... the reason for his is the level of test which does in fact trigger sperm production however, you will hit a time during your PCT that your count will be super low, if not zero.
To be clear, you ask a shitty endo they will tell you that "testosterone had no direct impact on sperm production". This is in fact not true.
I had to go through this for the last year and I kept a strict log of tests, blood results, and sperm results. I also had tests done almost every 45-60 days so i can understand the impact of clomid, nolva, and hcg on my body.
my boys are biggest they have been in 8 years, I can get fully hard, test levels (feel) normal at this point.
I've now added HMG to the mix (my doc didn't even know wtf this was).
I am due for both blood work and sperm test in April, i'll update in a month
keep in mind that it normally takes around 75-90 days for sperm to go from production to maturity to being released by the testies
