Stack Details

Vintage Blast™

Unlike other pre-workouts, the unique two-stage formula delivers steady energy and pumps. This means no crashing, no dependency, just amazing workouts and gains. More Details →

Directions: Mix 1 scoop with 14-16 oz of water, 15 to 30 minutes before your workout.

Vintage Brawn™

A blend of three protein sources: eggs, milk (casein + whey) and beef. It is far superior than any single-source protein like whey. More Details →

Vintage Burn™

A highly effective thermogenic fat burner that helps speed up the body’s metabolism and convert stored fat into energy without wasting muscle. More Details →

Awesome stack

Have been taking Old School Lab products for a good bit. This is definitely my go to stack. Blast does what it says and doesn’t cause a crash afterwards. Brawn has one of the best textures when it comes to protien powder, and all the flavors are spot on and smooth
