About Stacker 2

Stacker 2 (or Stacker2) is a supplement brand developed by NVE Pharmaceuticals. It was launched in 1997 and is based in Andover, New Jersey.

Along with Stacker 2, other brands in the NVE portfolio include Dexatrim and Not Just (a brand of protein also sold on the Stacker 2 website).

The parent company says it maintains a “commitment to quality” that ensures all Stacker 2 supplements are manufactured to current Good Manufacturing Practices (cGMP). Furthermore, all finished Stacker 2 products are inspected closely before packaging to ensure they meet the company’s exacting standards.

On the NVE Pharmaceuticals website, the parent company states that its “experienced team of scientists and production managers” keep a close eye on “every stage in the product development lifecycle”.

Stacker 2 energy products are made in NVE’s 45,000 sq. ft. “state-of-the-art carbonated and cold-filled beverage-canning facility” that produces “800 cans per minute”. According to one of the brand’s promotional videos on YouTube, its high-speed liquid-shot-filling lines are based in another 250,000 sq. ft facility, which is capable of producing 30 million bottles per month.

Meanwhile, Stacker 2’s six high-tech blow-mold machines can produce 7.5 million bottles per week.

Such large production capacity means that, in addition to producing its own brand’s products, NVE also acts as a private-label supplier to other brands.

The Stacker 2 brand mainly focuses on energy products, but it also makes and sells testosterone boosters, creatine, post-workouts, protein powders (using the Not Just brand name) and nitric-oxide boosters (for muscle pumps).

Stacker 2 is a well-known brand in the United States – and it boasts endorsements from the Pawn Stars team, Tony Sirico (Paulie from The Sopranos), Triple H (WWE) and even Ozzy Osbourne (British musician).

In addition to its stateside presence, Stacker 2 also boasts a Europe-based website,, which launched in 2010.
