I have had a great experience with misterolympia.shop, I have purchased previously through my dr and a compounding pharmacy and so I did have a little bit of a challenge deciding which brand to choose, however after a quick email back and forth with them they helped me make a decision. They then followed up with me to assure I was satisfied with my order. Great customer service, great product! The only reason I did not give them 5 stars was the cost of shipping. I am an entreprenuer and have to ship things regularly. The shipping cost was extremely unreasonable. After the positive experience I had I just went with it however it would make me think about shopping around a little more next time for better shipping costs.
