EZese and Irishpride,
I think it takes quite a bit of the stuff to overcome overtraining with PE, and you can get to a point where even high doses won’t give you a real hard erection.
Are you doing PE now?
If you are, I suggest taking a break for a week or two and see if EQ (erectile quality) improves. If it does, it is a SURE indicator that you are abusing Mr Johnson way too much.
When you start back into a PE routine, cut way, way back on it.
In general, once you see EQ start to drop, cut back on the PE routine or increase rest days between PE days.
One more thing, make sure you shake the vials real good before you take out the dose, the stuff can settle to the bottle and cause the rest of the liquid to have a much lower dose in it.
