CBUM

The CBUM line comes from Raw Nutrition, founded in 2019 by Dom Iacovone and coach Matt Jansen. Six-time Mr. Olympia Classic Physique winner Chris Bumstead joined as a co-owner and partner in 2021 and launched his own pre-workout and protein line under the brand.

NorCal Nutrition carries CBUM Thavage pre-workout in-store, formulated under Bumstead's own name for his training style.
