Hey welcome aboard. I’m 53 I lifted natty 15 years. Since then 20 plus cycles . Personally I think easier to stay lean natty . No kidding . I been bodybuilding 30 plus and daily martial arts for over 40 years and I was in military so training up to 12 hours day was not unusual in my life . What Drew me to aas was the notion of deca easing joint pain . Enough of me - my point is really only you can answer most specific questions by either keeping journal , trial error . I’d start at 200 keep diary record moods, appetite sleep training progress etc . Take enough to progress as taking too much is always the temptation. However if you do this way then add higher dosage if needed over time you will control results easily, be able to monitor and maybe avoid sides . Like some one said too - keep AI on hand compounds like aromasin letrizole are powerful then you got partial old school compound like novaldex / tamoxifen that is weaker but site specific concentrations on nipple area to control gyno sides . There also adex take EOD .25 will pretty much halt estrogen but also sides come along . Winny is one of my faves but honestly useless as stand alone cycle . Winny along with test or those deca dudes will compliment the other compounds by drying out the body through different pathway then AI . Depends how far you decide to go. Proviron also used to control estrogen harden up along with test but again more compounds and doses equal potential of more sides . If you have cash modest dose of test and 2-4 iu HGH together would go together nicely to harden up keep muscle and at your age the hgh will benefit. I began aas in my 30s , later I became remailer for guy and payment was keeping hgh kits for my help . I used generic too and in my 40s without extreme diet I had my erector Christmas tree fibers showing through skin, striations in pecs etc. you seem to be good now so avoid investing too much in chemicals but if I had to limit test , hgh and an AI ( I keep supply of novaldex and adex always on hand ) my advice always is you are your best teacher . Your stats to me are already awesome . So good advice from other guys on this thread . Mine start low slow listen to your body resist the temptation to go higher let the effects work , before you go higher
