I've took 5 injections from the same vial without any problem, but now its my fourth week on Test Cypionate and I notice that my last two injection in my right and left Delts are sore and have been for 4 days well my right one has for 4 days and my left for 2 days of being sore. I havent got a fever or chills...And it doesnt look red, but it is sore and maybe a little swollen, it hasnt gotten worse just the same, but i keep ****in with it so its getting tender. Could my vial got contaminated or what i'm very sanitary... I never been sore that long So is it an Abscess or just sore..Im going to the doctors tomorrow anyways, just curious guys....
