ROAD WARRIOR is right, it soulds like a hemotoma. I've had one. It took over 3 weeks for it to go away. It started shrinking after 2 weeks when I stuck a syringe in the middle of it (DAMN that hurt) and drew about 2 1/2 cc's of black blood out of it.
Btw what shoots in their glutes anymore? This is 2003... gear goes in your bi's, tri's, delt's...and calves for those lacking them genetically. I only know one guy (in real life that is, not online) who does glute shots.
Ttokkyo labs? Shitty company bro, they were decent at one time, but some friends and I aquired a large assortment of their goods, factory direct, at a good price... most of it was fake or underdosed and two guys who used it got a mild abcess. Of course one guy on his 2nd cycle used 300 mg of deca per week (one bottle out of the batch) with proviron and gained 25 ibs of lbm and his bf went down 4% (along with a 2" reduction in waist size)...go figure. I think they put everything that was suppost to be in the package in that one bottle...
