i dont think so... i mean it makes no sense physiologically. you will only stop producing test if you take more than what you produce.
lets say you produce 50mg test a week.
you inject 25mg on monday. thats what you would produce in 3.5 days naturally. youre gonna have LOWER test levels than you would have naturally about 3-4 days after that inject. your body WILL produce testosterone to even that out so that you dont come out lower.
why would your body stop producing testosterone if you just injected 1mg ? makes no sense. natural testosterone production varies anyway, on a daily basis and depending on food intake etc.
its not like your body senses OH THERES 1MG TESTOSTERONE MORE IN MY BLOOD, IM JUST GONNA STOP PRODUCING ANYTHING FOR NO REASON
nah.. that's how it works.
you take dbol or anavar or eq or whatever, and even though it's not testosterone, you're natural production will cease (or at the very least drop your levels below 100).
body produces 8-12mg/day.. so lets low ball and call it 70mg/wk. now, if you inject 70mg/wk, your natural test will but cut to shit after 3 weeks... try going off and getting bloodwork a couple weeks after your last injection, you'll be wayyy low.
same with other AAS. take 20mg halotestin by itself for 3-4wks and get bloodwork, you'll be sub-200/300 at least.
