RE: BD Prop or Virormone?
Virimone is IMHO the best prop you can get BUT only if it is real.
There are just so many floating around these days that are nearly exact copies of the real product it would be a risk to buy. I know of many sources who are confident of their supply route to real product that will not stock anymore as too many people will not believe they are real. Then you have the physcological element where if they are not Ronnie Coleman in 3 days then it must be fake and hence why too much hassle to stock. So not only is is highly faked but hard to find ion the first place.
You could look at other props such as Testopin (again a painful jab) or Testovis (very hard to find similar reasons to Virimone)
As for BD mixed reviews. I have read many threads from Gripperdog who loves it and no pain so seems user specific but at least real and competitively priced now it is in 20ml vials
