DIRECTIONS FOR USE: Mix 1 rounded scoop with 4 fl. oz. of water and consume the entire serving 30 minutes before workout.

After your body has become acclimated to the power of Endothil, you may increase the serving by 1/2 a scoop per day until you reach a maximum serving of two scoops.

Additional Information

Musculogenic Cell Recruiter* During an independent, double-blind, 6-week bodybuilding study on 31 fit males, the functional compound in Endothil-CR significantly increased upper and lower body strength after concentrated exercise (as measured by the amount of weight participants could bench press and leg press). Biceps circumference also increased significantly over the placebo group, who were on the same bodybuilding program.* This discovery led to Endothil-CR… a unique and proven method for muscle size and strength beyond what is acquired through the normal recruitment and differentiation of progenitor muscle cells.* Finally, a way to assist your bodybuilding program for muscle and strength without steroids or steroid-like precursors.

The clinical trial on Endothil’s key ingredient was conducted using the precise amount in the recommended one-scoop serving. However, you may find your body responds most ideally to a 1.5 or 2 scoop serving.
