In my case,I first started out in the 70`s with orals...........of course,I xcycled on and off.
The most I used and it was quite a bit for contests,was maybe 2 grams,but I would peak at this amount over time as the contest neared,stay on this highest of dosages for a couple three weeks as the contest got nearer,then would cycle back down slowly,then go off for long periods of time generally but I would often cruise not that we called it cruising,we called it clean! LOL

In essence again in my case,I never stayed on the higher dosages for long periods and these were mostly done since I tuned 39-40,not when I was younger battling my addictions off and on for decades.
Key point,I never considered my use as being abuse...........abusers who stay on huge cycles of tons of esoterics stupid bullshit cycles in pursuit of a card are just mostly wasting their time and usually end up with gyno and in some cases,a whole lot more.
Plus I ate like a fucking monk and trained balls out at every session for years and had tunnelvision pre-contest which is when I used the most gear,(still nowhere near considered exhorbatant by the standards.
Moral..............be conservative unless you actull have the potential to become a pro,something I relized would never be in the cards for me.
I consider myself a journey man and loved the challenge of forcing myself by diet and insane training to reach my personal peak condition.
I did OK for a guy who was pronounced dead 3 times and didn`t start my most serious comeback until I moved to Florida at age 39.
67 trophies later,I won one Over-40 Mr. Massachusettes title as I was the only competitor,though I had no idea who would show up.
Moderation and common sense is key,and yes,I never used PCT in over 35 or more years of drug use.
Baby dosages then and minute dosages by todays standards.
