Good point. However that leads to the question - why does all the science say that using synthetic testosterone not only replaces the product of the body's own test but also is supposed to be a contraceptive, as your body doesn't produce semen, only cum due to the body itself not producing test?
I've always wondered myself. I think it's bullshit meant to scare people off, but take it for what it is cus all rumors start somewhere. If you're worried about it particularly, and if I'm real honest you shouldn't be with only 300mg test, just HCG will do you fine. Make sure it is legit stuff from a reputable source obviously, I can't give you advice on how to use it though as I've never done so myself.
I've come off cold turkey from a 3g+ blast of test tren NPP EQ and Masteron and my sex drive was dead for all of 1 week LOL. Came off cold turkey again after that after some issues with the gear I was running (thought it was primo at 100/ml, turned out to be EQ at 300/ml) and had no sex drive problems. No PCT or anything. Got some nasty acne, but I attribute that mostly to my terrible 'lets get fucking huge I'm on steroids' diet'. Also became real asshole to room mates. LOL.
