No, Penatropin has not been made available to buy over the counter yet. I think the main issue for why Penatropin isn't available in stores yet is something to do with the distributors of the product, so nothing to do with the FDA or any health concerns associated with the product.
However, you can still buy it online from a number of web retailers, and Penatropin really does give you a testosterone boost or helps you recover more quickly from physical challenges like working out and hitting the gym.
As for the claims that Penatropin helps you get a bigger penis, that part is not actually true.
I have been using it for some time now and have not seen any change in that department.
But I do feel a bit more energetic and ready to go after taking it, which has helped me when I don't feel like hitting the gym on a lazy rainy Tuesday morning for example... so it does have some well-being effects.
Just be wary of where you buy your Penatropin from, especially if going down the "online route" as statistically that is the way you are most likely to get scammed.
Stay safe!
