Mid 20's I did a couple cycles as friends were into it and they hooked me up with gear for bike work. Stopped working out and gear for 8+ years or so cuz I really got into motorbikes (stunting and racing) and I also lost a lot of weight because weighing less made it a lot easier to do what I was doing.
Fast forward to mid 30's. Ive got 2 kids so thats done, and I was doing a bit of drinking so I cut that out and started working out again. Putting on a bit of weight, albeit slowly, and still feeling in the dumps. The feeling reminded me of coming off cycle all those years ago, and so I finally got checked out and got a low T diagnosis. I was using GH at the time as a sleep aid for insomnea (which worked well) and so I emailed my rep asking if he had AAS as I had a feeling TRT would be an uphill battle with my Dr.
I had it in hand in no time, and I went back to the Dr to talk about my results, and TRT. The answer was No because apparantly I was still in the 'normal' range. I didnt press the matter. I went home and pinned some Test and Ive been blasting/cruising since.
My only regret is taking all those years off. But I'm catching up slowly.
