I know it is EXTREMELY rare but I shut down my endogenous test production for life.... I have to take freaking 100 mg ( YIPPPPPPPEEEE) of Cypionate every week for the rest of my life.. Oddly enough I was able to perform sexually fine and still do but I like to have the added benefit of Viagra..
I woudl REALLY stay away from Nandrolone based things... Stick with Test, always run Sarms etc...
FWIW, I was taking WAY too much shit... Like I was pry on a BASE of about 4 grams f test a week for 8 years while taking A bombs, Reforvit, Winny, and other Dbal tabs and yes I know Ref b is D bol..
I would GUESS at I was taking an average of 5-6 GRAMS of injectables a week and probably 500-600 mg of 17 Alpa Alk orals for many many years... I have produced 2 perfect kids btw..
Which I was really worried about because of DNP use. BE careful.. My liver is ruined.
Its HARD to ruin yourself on anabolics alone, but it is pssible fr sure... My Endcinologist works with many pro athletes and and Bobybuilders and he told me I am the only person he ever witness PERMANENTLY shutting down test prduction...Lucky me
