mod edit: we recommend posting this in the proper forum.
Uhh first age? training experience? Diet? and if you did your research you would know the strong ph's and know that with a strong ph there wont be minimal sides. You can do your best to prevent those sides with properand PCT but when i see someone refer to minimal sides i think something like trifecta or h-drol. Now at 5'8 140 my guess is you dont need a PH But rather to EAT and im just stating this because everyone else will. Im not going to suggest anything else because i dont think you have done your research or are ready for a PH. Just my personal take because you can gain a lot just by proper diet and training and i dont want you to risk taking a PH when you can gain from food.
I have properly ran a previous cycle of Warrior which contains Tren, Epistane, and Superdrol. I have finished the cycle and have pct'd and am doing great. This supplement, warrior, was recently pulled from the shelves of my store so i was looking for something that was relatively strong like this so i could take it.
i think jumpshot said it best. if you have done your research then you wouldn't need to ask for a strong PH. so why don't you post a few PHs you have researched and are thinking about using so we can give you input on those products.
5'9" 155 and planning a second cycle? 6 years in the gym?
unless strength is your only goal from a cycle, i'm at a loss for what exactly you're doing...
let me phrase this another way. if bulking was your goal, in 6 years of training you should be well above 155 lbs. so what's your goal in this?
