True, it is dose dependant. 25 mgs a day can still be 5 times more than your endogenous T. Shit, I grew off that. Not much, but I did. And I (personally) did not need nor use any PC, and kept all of my (small, but quality) gains.
While T is certainly more likey to produce faster and sometimes "harder" supression, the drugs listed above CAN do the same. It is very dose dependant. 2.5 mgs for var a day may not cause total HTPA supression, bu then again neither will 2.5 mgs of T. 25mgs may cause it ( I dont think it did on me, but I did not have blood tests, so that is speculative). However, 50-60 mgs of stan certainly has that same abilty, maybe even less.
and as for one of the injectables you like: EQ, that drug is highly androgenic (not as much as test or tren, but moreso than winstrol, primo, deca [though deca does cause supression via different mechanisms]. a decent dose of EQ , ~400mgs or over, will most definately cause total supression, and fast.
