My first critique on this forum. Glad I found this site. Lot's of great info, as long as you weed through the personal arguments. Anyways rented twice so far from Herc. First was Tes E 250. Received in about 4 days, probably because I live at east. Had to pin as soon as I opened. Two cc noticed immediate body tingle, good sign of having something. Second was T400, received that in only two days after payment. I would stay away from the 400. I have used on and off for the past 18 years (both human grade and ugl) and I have used denkall 400 2 cc at one time. Never have felt this much pain. It has been 6 days my glute is still swollen and hurts to the touch at injection site. Have had this happen before and it was a sterilization problem. I would recommend Herc and his 250, but would be wary of the 400. I am contemplating not even using the rest of the two 20m bottles I have. Will update in a few days.
