Tren by far... suspension will but not like tren/parabolon/finiject...
I noticed oen thing over the years.. 75mgs EOD or a total of 225mgs ,give or take 50mgs, was teh best dose.. I have done 300-500mgs a week and all it did was make my prostate swell like a balloon and my kidneys scream. I got no better results at 225 or 500 jut lighter pockets and health issues...
Infact I know a few guys who do very very well at 150mgs a week.. just doing a shot every 2-3 day did the trick to keep blood levels elevated..
Hope that helps with info on personal experience... BBB
