“Amazing products. I am a fitness model and the OSN Nitro XS is incredible!!!”
– Damon

“As I was once a gym rat in my early adulthood, I was eventually distracted with academic priorities in college and fell astray from my old bodybuilding ways… after graduating, I needed something to help me get back on track FAST and most products wasn’t going to cut it for me. But that was until I saw a young male at the local gym who happened to be ripped, lean, and ABSOLUTELY merciless with the weights and of his methods. His sense of muscular recovery was really in a way, f’in hard to believe, his strength was off the hook, and he was just picking up the ladies, scaring off the boyfriends. I asked him how and he said OSN… and for two months now, my life from there on embarked on a new journey as I am now a true BELIEVER! THANKS OSN!”

“I was one of those who got suckered into paying $70.00 for a one month supply of Force Factor. While I think the product is good I was surfing around the net and found the same formulation for half the price the product is Nitro Load. Anyhow,OSN -Octagon Sports Nutrition (you guys) had basically the same product and worked just as well. Thank you OSN, I will be back for sure.”

“I just want to say that I have tried only 2 of OSn products so far and both seem to be right on with the description.  For example Nitro Load from Octagon Sports Nutrition – OSN® is a powerful muscle building formula, designed specifically to increase Nitric Oxide (NO) levels in the body, resulting in maximum muscle growth, strength, and endurance, along with a continuously pumped physique. If you’re serious about gaining lean muscle mass quickly and naturally, then Nitro Load will no doubt help you achieve impressive results faster. Safe and effective, this formula has been used successfully by thousands of professional and amateur athletes, from fighters to bodybuilders, and is backed by nearly 40 years of research. Known as the muscle’s “cell signaling” molecule, the body naturally produces small amounts of NO, which play a role in oxygen delivery, blood flow, glucose uptake, power output, nutrient delivery, and muscle growth. I have to say that I agree 100% with the details of what this formula can do.  Thank you OSN”
– Dean

“Have tried osn and loved it  and had alot of my people hit you up to try out the best nutriton out in the market. Have been waiting for my free red goat to come in. Tried the pre work out you all sent to me and I’m ready for all you got to give, I stand behind this stuff 100%”
– Jeffrey Clayton

“I used Nitro load extreme while training for my last fight. I was able to push harder, last longer and i felt stronger during training camp. I won my fight in 2 minutes of the first round and OSN was definitely a factor. Im looking forward to trying out more products. Thanks guys!”
