To a level more is better 400mgs is going to be better than 200mgs, 600mgs is going to be better than 400mgs but there is a certain level were more isn't better and this is all individual. Sides come on quick for some and some cant handle the side effects were others sides don't appear until a certain level is breached. But I must say something really magically happens to the body at a certain dose and you'll never experience growth like it. Ive seen it many times but ive also seen the opposite were dose does nothing for the person. It all about learning about your body.
I never got any kind of gains or felt anything with primo until I reached 1500mgs then I felt it, I know guys who love it at 600mgs and think its remarkable well 600mgs wouldn't do shit for me and would be a complete waste of time. The bigger I got and the more muscle I carried the more dosages was needed to make further gains but once I held a certain weight/size for so long say around 1-2 yrs it was a lot easier to lower the dose. Its all about resetting your homoeostasis system so to speak.
I'm going well off topic here but ive not been on AAS for 2.5 yrs in December and I wont need anything like I use to take, I would grow now of 500mgs-750mgs very easily infact I will explode I know I would. I went through many stages with AAS but how I trained and kept consistant over the years with every aspect of bodybuilding is what made me keep my size, when I was younger every 10lbs was a fucking nightmare to achieve until I started to listen to my body, designing the right cycles and training in a style what my body just loved.
Yes, your right ive only ever done one cycle in 31 yrs,
Ive done nearly all the combinations of cycles going but I would say I was a heavy user, I always went on the heavier side of things because I had to otherwise it was hard to get to where I wanted. Some guys don't need to and just look at 400mgs and roll a 25lb db and turn into monsters but I wasn't I had to work very hard at it.
I would create an environment for muscle tissue to grow via priming a slow glycogen depletion without losing any tissue, then I would hit a cycle running at a dose what would make my body think wtf, then I would increase my cals and all this would land just right coming out of a pullback into full bore HIT program and the result was huge increases in size and thickness. I was taught this method by Paul B one of DY's friends and advisers when he was going for the British title. Everything had to be lined up and I was one of those who responded well to gear but I was done after around 6-8 wks and all what happened after that no matter what I did like changing compounds or dosages was side effects would creep in, so short cycles were far better for me in everyway. I'm not saying they are for everyone because they not but for me and my body they were ideal.
