If your unlucky when you come OFF you will have a hard time Getting hard. Without pct this problem could last over a year.
Another thing if, if you get gyno, you will not know if its from the testo wich you can treat by using for example Nolva. But if its from Deca your fucked.
And you probably dont even have Nolva or adex at home do you? :/
I think impotence on cycle happens too with nandrolone. Prolactin drugs might help although they have some rough sides, not sure, I don't know much about deca.
Consider HCG or HMG to maintain nut function.
Your "weekend horny" was pure placebo.
BTW, I think you're full of shit and haven't taken anything. You're just attention whoring. No one would be stupid enough to start shooting hormones without knowing what they're doing... right?
