FSU Serum is here from the sorcerers at Inspired Nutraceuticals, and not a moment too soon. Far from being a merely aesthetic boon, getting a gnarly pump improves results. From enhanced performance to faster recovery, pump-inducing supplements are built to take training to the next level.

Every major athletic supplement brand on the market is getting into the pump game, utilizing ingredients like nitrates, betaine, and – of course – glycerol.

Beyond achieving results, the other side of a successful supplement is consumability. Glycerol is notoriously difficult to work with in powdered form. In order to avoid clumping, nearly all glycerol supplements on the market need to cram in loads of silica.

As a result, most products are so diluted that they fail to meet the studied and efficacious dosages of glycerol required for that pristine pump. FSU has solved this problem in the form of liquid glycerol. The dose is loaded and it's only the start of this formula.
