Good Product

Can't even tell that I take these. They certainly have good reviews. I just wish that they'd work for me.

As a competitive NPC physique bodybuilder I have tried all the latest and greatest supplements around. I came across this brand and thought I'd give it a try but what more will this offer me that others don't. Well my honest opinion and feel free to check out my results getting ready for my next show @Gavmac1987 , I am pumped all day with constant blood flow to all areas of my body I'm working out. I catch myself looking in a lot of mirrors lately to admire my vascularity. This products delivers exactly what it says. No need to lie about a product that shows results even outside the gym.

I hadn't taken a pre-work out supplement since college, but I'm sure glad I tried this product out! I feel a nice pump throughout my workout and have seen great results within the first 30 days. I do intense circuit training and, previously, I would have to slow down and didn't have that extra stamina to make the final push. That has totally changed since I've started taking NitriGen... I'm able to push through those tougher parts of the workout and make it to the end. Such a great product!

I'm not an athelete ,but I wanted something to help me workout longer without feeling exhausted. I tried some other pre-workout products that my sons used, but they made me feel jittery and hyper. NitriGen helps me exercise longer with no hyper feeling. It's the only pre-workout product I will use. Thanks for making a great product for people of all fitness levels!!!

I know a lot about supplement and Spear now has the best products on the market. NitriGen is truly powerful and brilliantly formulated The owner Spear is a brilliant Stanford grad who is taking supplements to a new level. I'm very impressed! Dr. John Grady
