I ordered 3 vials of testosterone 400mg 10ml from Aurum Pharma and 2 vials of 500mg 10ml deca from Ultima Pharma and I am very familiar with both of these products as it is not my first order. What I can say is I don't know what I would do without the joint relief I get from the deca lol. It's a game changer especially for those of us getting older and more prone to injury. I really appreciate Napsgear always having the top quality gear I need at a great price and always shipped to me in less than 5 days. Customer service if you ever need it is great as well. Placing next order very soon thanks again Naps.
