Hey I am new here but not new to the game. I do quad shot's also and I took a shot of Sustamed 250 and it was the worst feeling I have ever felt. The next day I could hardly walk and the leg was red and hot to touch, after doing legs to get the juice flowing it went away a couple of days later. That Sunday came and my next shot was due, so I took it in my other leg, well hell if I didn't have the same issue but this time it didnt go away and kept getting worse. I finally went to the doc, I had to lie about what had happened because I am in Iraq and I cant tell them I am taking juice, told him either a bug big me or an infected hair, he looked at my leg and said I had CELULITIS, gave me a shot and some pills and sent me on my way. I threw out the rest of my Sus 250 and I will have to try again later with different stuff. You never know what you are going to get even with a good guy or company selling it to you... Hope this helps and you get better.
