T3 Speeds up ypour metabolism like crazy and puts your body into fat burning mode more often causing your metabolic rate to increase as well as your thermogenic rate. This will account for the sweating.... Basically what im telling you is everything your feeling is perfectly normal and you need to take advatage of the T3 and eat. Eat as much as possible pro. Sounds like you got some good stuff? care to tell the Brand? Id also Recommend some hawthorne berry extract to account for the Blood pressure rise. Should a little bit much not much to effect. What else are you taking with this? As well as your current age and stats, cycle history and current diet and training regime will further assist.
Thanks
