My opinion on aas: There's no use blasting crazy doses because you can't hold 280lbs with a reasonable dose long term... you're just gonna gradually get smaller and smaller, which to me is pointless. I think if you decide to go on you should stay on... using TRT between short cycles to put yourself at high-normal and when you can no longer hold anymore using that TRT dose never go above high-endo levels again because its detrimental to a) your health and b) your sanity. In saying that I don't know how much you can really hold with 150-250mgs even if you built the mass slowly using food as the main anabolic etc (If it's true trt why can't people hold mass after a cycle, do 3 cycles gaining 10lbs each and wind up 30lbs heavier without the need to touch juice again)? I do know that your test production will get lower with every cycle though (if you do cycle) resulting in this massive yo-yo effect when you come off, which can't be healthy along with everything else... I think you're best accepting the inevitable and using trt straight away. though at 21 I'm not comfortable doing that.
As a natural its easy to make goals and plan because no variables are changing, but as soon as you cross to the dark side everything is tied to aas use and compromising your health... and that's what frustrates me most about the sport. / My 2 cents.
