The pump you get from Viagra and Cialis is not specific to your dong, it's systemic just like the pump products your taking but it works 10x better. Viagra and Cialis does not make you get a boner. It just makes you get better/harder ones when you want them. You could use a pump product in a similar watered down fashion.
I was joking about the anadrol, obviously only a steroid user is going to take that pre workout, (which is awesome lol)
But low dose daily Cialis has all kinds of health benifits and will completely eliminate your need to buy a pump product. You can kill 3-4 birds with one stone. Given you are a responder to those drugs, some ppl don't respond to them .
