so i was looking at these products in liquid...i think i saw it at 50mg/ml at 60ml.... price was really cheap considering i would only take 25-50mg when i need it... with the liquid u just drink it right and not inject it right??...also why is the a bottle with around 60 serving so much cheaper then buying the pill which i saw at a few bucks a pill..sorry also another question im 22 years old...taken a cycle here and there but my sexual function is pretty good...i took viagra once and i felt like a new man...was wondering if it is safe to take even if i dont have ed...
