what the hell is going on please help? please read

i pretty sure on what it is, but why? i have been using 200 mg of prop for years now on and off cycles plus a few others mixed in. i have been using quilty vet always but i found a great deal on some nutri-vet just started a cycle of nutrivet 100 mgs plus hgh and t-3 and clen. i did a onsite injection of hgh on my triceps no problem i did a 50 miligrams of prop and 25 miligram of winny mixed in each bi-cep(.75 I.U.s each) i know prop hurts but my right arm is red and twice its size it hurts like a mother. i have been on antibotics to fight the infection it seems to be working still cant move the arm but getting better. Is this just from nutri-vet being a piece of crap gear or when this goes away should i resume cycle or just through away the gear

could be dirty gear there are ways to sterilize it i beleive through heating, perhaps someone with more experience can help here?

give it a few days, sometimes you just have a bad shot, it happened to me where ive been injecting prop(qv)for about a week no problem but this one time i shot 1cc in each shoulder and couldnt move them the next day.. the pain was unbelievable and i also got sick for about 5 days.. it went away by the end of the week and ive been fine so far.
