I took this twice daily as suggested and noticed absolutely zero effect. Bought it at Rite aid, and although the label implies a 100% satisfaction guarantee, there is no provision to place a claim on the product website for retail purchases.
I decided to cut my losses rather than waste my time chasing ghosts. I would NOT recommend experimenting with this product.
Bottom Line: No, I would not recommend this to a friend
I did try it and it didn't do anything for me. If you take it and have hypertension, check your blood pressure daily. If it was that good, why is it not prescribed by your own physician? They show individuals including so-called medical authorities or doctors in their testimonials but these are paid. Besides, at the bottom of their ads read their disclaimer, which means they take no responsibility for it.
Once you order the free bottle, do not give them your card number. If you try to call them for a refund you, get a chair, it will be a long wait. This is a scam like many seen on the internet and TV. Don't give them your card, and if you are curious enough just order a free bottle but don't authorize them to ship you a second bottle automatically. They'll bill you. For your ailment, go to your physician.
