I have but won't bother again,you need to be fucking pin happy for this stuff.basically there is no ether attched to the test,neither does it hold together in the vial well.If your using ugl 10ml you need so swirl it round to get near matches in the shot,i used pharm.As for the pin happy remark,try going through 20ml by jabbing morning and night.No thank you I'd rather chop a hand off than do that again,prop is fine but try rotating 4 site's on the stuff.It's not needed at,the only benefit of it is no ether weight so 100mg's is 100mg's.Not enogh of a pro when your glute's are making a slight pop when your going in,if your new to juice this will not suit you...unless of course you like punishing yourself in a really sick way lol
