Query: very impressive!

I have been taking lipidshield for three months now. My bad cholestrol hasdropped 20 points in three months while taking two pills a day. I now take just one pill a day for substanance. I have high blood pressure and I noticed that I cannot take lipidshield and drink caffein for it raises my pressure, I believe it is the guggulipid in it . I used another product first that had guggul and I had to discontinue it completely. All in all I am very impressed with lipidshield.CJ
