I have found, if i keep my test lower...I can run really high doeses of 19-nor(deca,tren) with very little sides.....The higher my test is, the more i experience these sides....
All you really need is a hrt dosage of test to keep everything running properly, even if they were using 900mg of deca/week
There is a misconception, that you must run your test 2x that of your deca or tren....but this is very untrue...
