Just my opinion bro but with your stats and age I would have gone natural for a while. Before your first cycle you must of been 160ish, not much of a foundation. The other thing is you put on 20 pounds in 10 weeks kept 15. If that's true ( Iam not saying it's not possible just unlikely in my observation) that just tells me you had some untapped potential. Most guys I know your age and size may put on plenty water size and lose most of it after pct because 1 their foundation and 2 their experience- and with experience diet etc etc. So what i see if all is correct is untapped potential. Since your already on cycle with that ester In your situation I would recommend 12 weeks and a second compound maybe an oral in the beginning 4 weeks. Eat huge. Get all your supporting supps and train. Good luck bro
you could run it 15 weeks but why? you have SEVERAL far better options than that... you don't want to run test that high bro... its completely unnecessary and your going to add to the side effects the higher you go... what is your main goal from the cycle?? what is your body fat? i can improve this cycle a lot but i need that info from you...
also, understand that you were EXTREMELY undersized your first cycle... there's no reason for you to not that put kind of size on when your that undersized... your at the average weight for someone 6'1" now... you SHOULD be that size... i am not saying you can't still make gains... What I am saying is to not expect every cycle to be that way and to also not think a test only cycle will continue to do things like that...
