The truth is in the test. I am a 40ish year old male and I have had high cholesterol for years! I have exercised, dieted, used garlic pills, fish oil and plant sterols to help lower my cholesterol, all of which seemed to work but then my cholesterol bottomed out and didn't go any lower. That's when my doctor prescribed a statin drug. No way!!! I wasn't going that route so I got to searching for something else to lower my cholesterol and that's when I found Guggulow. I followed the suggested use on the bottle and before my 4th bottle was empty it was time to get my blood work done again. For the first time EVER my good cholesterol (HDL) rose from 32 to 44 and was in the good range (>39)! My bad cholesterol dropped 33 points and my Triglycerides dropped 111 points. I never had any negative side affects from taking Guggulow, if anything I feel much better. One last note, I have always had oily skin and chronic sinusitis. I don't know if Guggulow had anything to do with it but my skin is less oily and my sinuses have never been better! Just something to pay attention to if you also have these issues.
