Ah bro, what your asking is like asking what the risk of getting an sti from the slag you met on tinder and then fucked in the ass without protection.
you ‘might’ be fine, you might do that many times and be fine or you might play by all the rules, strap on full protective gear only for it to fail and you still get the damn sti.
however, the risk profile changes. If you never do anabolics then the risk of anabolic use fucking up your endocrine system is zero.
the longer you stay on cycles and the less time you have off (which is when your natural homeostatic position recovers) increases the chances you’ll do long lasting damage to your own system. But there’s plenty of guys (on AM and elsewhere) who have broken all ‘the rules’ and recovered perfectly, likewise there are a few who did everything perfectly after one cycle and never fully recovered their own production.
IMO your age, whether you have kids already, whether you earn a living from your body etc all have to be factored in here.
I never suggest what others should do, just what to consider and what I personally do.
I started anabolics after having two kids and then the snip, so fertility was no concern, I’d also lost a tonne of weight which I’d had since my teen years, that meant I missed all my best natural years being a fat alcoholic so I’d never built the muscle then I potentially could have naturally, in my late 30s after 4-5 years of hard training I realised I wouldn’t achieve a look I was happy with naturally and I was prepared to trade the anabolic risks to achieve it (probably because of my fat younger years). Mentally it means a lot to me and the rest of my life is crazy healthy so I mitigate some of the risks. I cruise and blast (so my odds of full recovery if I come off are low) but I was prepared and I’m ok with being on trt for life from now.
I still take 3 months between blasts though. I get regular bloods (everyone should) and when I blast I try to make sure I don’t waste it. Personally I feel like 3 months is the minimum to let the body recover from a cycle/blast.
hope that helps brother. For what it’s worth I also love Deca
