Absolutely do NOT do this. Ever.Would giving a dog or a horse zinc supplements(safe levels of course)increase their semen amount like in humans? If so wonder how much a horse or dog would cum if it had the same effect.
Zinc alone is fairly useless. Taking 25mg zinc chelate (not citrate) along with 1mg folic acid can increase volume significantly in older men. Did for me!The effect of zinc on humans is to my knowledge questionably measurable. You may produce a few milliliters more.
