i have just done my first shot of 100mg/ ml prop and my shoulder is swollen!! when i injected it last night it felt like i was injecting fire into my arm and then it swelled within 10 min. it seems to have gone down a bit and i know that swelling is a common thing with prop but ive done sust before with a bit of swelling but nothing like this. i also read that it is warm this is a problem because mine is. no pain in the area besides a bitof numbness. i just bought 6 bottles of this stuff!! sh**ty!
