Norditropin FlexPro 10mg 30 IU comes in a reconstituted (pre-mixed) pen. Norditropin is made by Novo Nordisk and is a FDA approved Human Growth Hormone. Like all other FDA approved human growth hormone (HGH), Norditropin is a 191 amino acid chain. The nice thing about Norditropin is the FlexPro Pen comes in a pre-mixed pen that you dial and has a mg window. There is no mixing HGH with bacteriostatic water. The FlexPro pen comes with disposable needle caps, you do not need to mix or buy diabetic needles. The pen is by far my favorite and while other companies offer FDA approved pens, Pfizers Genotropin, Merck Serono 8mg pen, and Omnitrope's 10mg pen, the price of Norditropin is much better with the same FDA quality. I myself have been using the NordiLet pen for over 2 straight years now.
We used to carry the Norditropin NordiLet pen by Novo Nordisk, but they discontiued the model in Mexico. Now Novo Nordisk offers the FlexPro pen which is a better pen. The HGH in both the NordiLet and the FlexPro pen are identical, only the pen containing the HGH is different. The FlexPro pen is a sturdier pen with a window displaying the amount of HGH you are injecting, where as the NordiLet pen only has a dial, and you had to memorize how many clicks for your injection.
