I can tell you one thing.
When i was at 17-18% bf,went on some test and tren,300 test and 400 tren-e.My bp was fairly high,got headaches,overall i felt like shit.But i went on with it,and started loosing bf.Nowdays i am around 11-12% and i can tell you that at 300 test-p and 500 tren-a i am feelling like million dollars.Bp is damn good,no longer have red-face,much less bloat.
So,the leaner you are,less side effects you get.If i were you i would get into 10% zone as soon as possible,then start some 5iu daily and try tren-a 100 EOD and primobolane around 600 mg p/w.that will transform you for sure.But first get rid of some fat,remember,the leaner you are,less sides you get.
