Ive said it before but needto is a straight up dude and will not sacrifice quality for quantity.... and it shows. the extract he uses is tough to get but worth it. The last batch indeed sold out in a matter of days, I suggest you join ntbm forums since he usually throws a mass pm out when it comes in and when it does you get on and buy that sec. most of us will buy multiple bottles bc we cycle throughout the the year, plus hcgen makes you a gangster in the bedroom im talkin triple o.g. lol so yea it sells quick. If you need a quick fix double dose bridge , and its 25% off right now with needto25 march only.
