Dude, omnevol is a mixture of three steroids, all methylated and all liver toxic. You need either nolVAdex (tamoxifen citrate) or torimfene, clomid, etc, not this over the counter Novedex CRAP. You are probably getting these symptoms because of your non existant testosterone levels, messed up cholesterol and impaired liver function. I'd say you should stop immediately if you have access to Nolvadex and get bloodwork done to check liver and kidney function, as well as cholesterol.
^^^^^^^ and also, next time you run a prohormone it's best to use just one methyl at a time, 3 at once is brutal on your liver. i hope u didn't drink in excess while on cycle. Nolvadex is a must for your post cycle, your natural testosterone is most likely shut down. also you might want to consider some kind of tribulus product along with your nolvadex to stimulate some natural production. Novedex XT won't do u much good at this point. use google, you can find nolvadex without a script with some looking.
You should probably get bloodwork done to make sure your cholesterol is ok, and your liver enzyme count will be high, but that should go down in time, keep taking the milk thistle. you might want to add some fish oils, red yeast rice, coq10, or some ALA to help recover a bit faster. Omnevol is brutal, 3 methyls is way to much in my opinion, but I've read logs where people ran it, made gains, and turned out fine, so it's just my opinion.
Isn't Omnevol going to be pulled soon? I think I remember reading that before somewhere. Either way, evo labs is nuts for making a product that liver toxic.
If you want to finish out your last week is up to you, but if your sick, I think it might be time to call it quits and make sure you didn't screw anything up to badly, plus 10 pounds is still a great gain, add some creatine post cycle to help maintain some of those gains as well. I guess keep using it til u get ur hands on some post cycle stuff though. maybe slide back the dosage a little, what are u using per day? it's 2 caps right?
