I do about 20 sprays between calves, forearms and neck area. I notice benefits when I take it with b1 and/or D3. B1 and D3 both require magnesium to work. Supplementing either of those without magnesium will work for a short time, and then you're toast.
Interesting, but have you used just magnesium by itself? In many years of trial and error I've tried to use magnesium and it kills my libido. Same thing with vitamin d. Have recently been trying d3 oral spray (can sprays that are designed to be ingested be used topically instead?) with vitamin a and k but after a week my libido is tanking big time.
I don't see how two wrongs can make a right, meaning if magnesium and d3 both separately hurt my libido would combining them help or just double the negative effect?
