I was very nervous about trying a new company because the other company I was going through has went up so much. And when you get on higher doses it starts getting more expensive. So I gave Puratek a try and today is my first day and so far I’m loving it. I love how they give you updates on shipping. They also ship fast! But most of all I’m excited I found somebody that was reasonable compared to the other companies. You can’t beat their prices . I really recommend this company. Nice people.
