Blackstone Labs Extreme Mass Kit

Mass moves weight. Mass changes your look. Mass changes your presence. The Blackstone Labs Extreme Mass Kit combines three of Blackstone’s most aggressive muscle building formulas for athletes chasing thicker size, heavier lifts, and a more dominant overall physique.

This high powered stack brings together Blackstone Labs Brutal 4ce, AbNORmaL, and Chosen 1 to create an extreme mass building system. With testosterone-fueled growth from Brutal 4ce, dense anabolic power from AbNORmaL, and lean dry muscle support from Chosen 1, the Extreme Mass Kit is formulated to increase bodyweight without turning the cycle into a sloppy bulk.

What’s Inside the Extreme Mass Kit?

Blackstone Labs Brutal 4ce establishes the testosterone driven backbone of this mass stack. Built around high potency 4 DHEA, it helps create a stronger anabolic environment for rapid size gains, heavier training, and faster progression.

Blackstone Labs AbNORmaL pushes the stack further with 19 NorDHEA, a precursor to nandrolone. Known for its powerful anabolic profile, it drives muscle density, stamina, recovery, and the heavy growth athletes want during aggressive mass cycles.

Blackstone Labs Chosen 1 adds a dry gain edge to the stack with a 3 ester 1 DHEA system that converts to 1 testosterone. Because it does not aromatize, Chosen 1 promotes lean gains without the bloat that can come with traditional bulking.

Blackstone Labs’ Liposomal Delivery System

Traditional oral supplements can lose a significant portion of their potency during digestion, with absorption often estimated around 30–35% after multiple passes through the liver. 

Blackstone Labs’ liposomal delivery system uses protective carrier layers to help ingredients move through digestion more efficiently, supporting significantly higher uptake, with absorption rates reported as high as 90–99% under ideal conditions.

The goal is simple: more consistent utilization from each dose, without relying on excessive amounts.
