Alright, I actually have a few questions that I really need some input on. First, I bought Lipoflame about 6 months ago and opened it, read the bottle then put it on my desk and didn't decide to take it until now. But now it smells like vinegar. WTF? Is that common? I am taking it anyway, and it seems to be alright. BUT I am also currently on a Halo-Tren 400 cycle, and I've been experiencing some serious muscle stiffness and cramps. I have em in my neck, my back, my arms, my legs. The product is very good and I have gained very noticeably in size so far, but I'm in the last week of taking it and I'm experiencing cramping and stiffness that I have never experienced before. Anyone else ever experience this with similar supps? The rest of my supp plan is as follows: Xtend, Multi-vitamin, Kre-Alkalyn, Fish oil, 3 oz Mona Vie, Whey protein isolate, either advil or low dose aspirin, and as I said before, Lipoflame.
