Holy Necromancer!
It is an interesting concept if MoS had their own pills that were made looking out for better blood flow, enhanced erections etc..
I'm tooting my own horn for a moment:
Supplements I've tried
Anybody coming to his thread and going through it, there are good supplements available.
One magic pill doesn't give you inches of length and girth.
They're supplements and some of them are pretty great.
Keep on doing workouts: you can make gains using your hands!
With that said, a proper diet, hydration and enough exercise are the building elements for a bigger, better you.

You can take some supplements, a good multivitamin is quite safe as it is.
Check the thread I linked and other ones as well. Maybe we'll get a nice supplement in the shop, but I'm happy as it is due to the amount of tools available!
