Supplements fucking up libido. Any recommendations

I'm a below average OGer, so I am used to being able to go like 7-8 times a night if I want to... So this problem is a big time lifestyle change.

I got some Black Powder, for a pre workout and my dick crashes when I take it.

Same thing happened with the shit that they sold me at GNC.

Also... I took some Tribulus and it did the same thing (though not a pre-workout)

Any recommendations on something that I can take that won't do that? I switched to an early AM workout and need something to get me going. Phone Post 3.0

Eat natural foods and stop taking that garbage.

I had the same problem with pre-workouts.Stopped taking them and just take straight creatine. All is good now Phone Post 3.0
