Animal Nitro. Old school meets new school. We’ve taken tried and true classics, amino acids, and brought them up to date for the serious lifter who’s looking for something more. Listen, amino acids have been around for decades and have been used by countless athletes. As supplements, they’ve stood the test of time. They’ve also been studied in great depth over the years. And those studies are always moving forward… Recent research suggests that amino acids help support an anabolic environment.* But that research also suggests that timing, dosages, and the mix of aminos are all extremely important. To get things rolling, you gotta start with the right mix, forms and types of aminos to support the maximum anabolic advantage.* Animal Nitro’s got it all.
