Not intentionally trying to offend anyone but in my experience and opinion, this type of "special formula" BS is just that, BS! It bothers me that there are many young and easily influenced people that are probably jumping straight on those dosages without even trying something conservative first, just because a so called expert "says it's so".
My personal take on it: Way back when I did use super supplements, I could never even come close to handling those type of dosages and I was not a small man. At around 5' 8"-9" I was 265 and fairly lean. I was a powerlifter and I felt and grew/gained best off of dosages between 500-750mg/wk (depending on the compounds used) and that was after years of off and on use. There is NO WAY I could've even come close to handling 1,800mg/wk EVER! I looked like an in shape offseason bodybuilder most of the time and would drop below 10% body fat briefly for summer vacations... I could still look massive while getting lean on just 150mg Test Cyp, 50mg Drostanolone Prop, and 50mg Tren Acetate PER WEEK (not a typo, 250mg/wk) divided into small daily doses. I would still maintain or maybe even gain a little strength off this while getting ready for the beach at the same time. I felt "off" if I ventured north of 750mg/wk in dosage and my body, well being, and performance would all suffer when I tried it. I know there are many that can and do go well beyond that with their dosages and somehow gain monsterous size and strength but those people probably have superior genetics for bodybuilding that I don't posses and neither does most of the population that are into what we are into here on PM...
Off topic: Not a joke but kind of humorous because I thought it was a joke and laughed when he told me. I know this man, 50 years old ,6' tall, around 240lbs, in decent shape, and he told me that he had only done 1 cycle his entire life. I said WOW, that's impressive. He said yeah, I started that cycle back in 1995 and still running it. I laughed and he said no, I'm serious, once I started it, I never came off. He has been on Test and Tren (and other compounds) for over 22 years straight and still going. He's never competed in anything and has never trained his legs. True story...
