Oh man another member who has not figured out how to use the search button.
None of them are FDA approved. Any kind of pill has a side effect.
Of course a pill alone won’t do jack shit. If you took a weight lifting pill (creatine, ripped fuel) but you didn’t lift any weights do you think you would get bigger. The answer is no. A pill along with PE won’t hurt (your dick) but the money you spend would be better spent on a good diet of fruits, veggies and protein. Plus who knows what those pills do to your heart. Stay off the pills, start on the newbie routine and then buy a $5 cable clamp in a few months. And don’t hurt yourself.
