Blackstone Labs Chosen 1

Blackstone Labs Chosen 1

Blackstone Labs Chosen 1 is a revolutionary muscle-building supplement for the aggressive athlete who wants to maximize lean muscle growth without unnecessary fat gain.

Traditional bulking often comes with a dreaded tradeoff: increased body fat alongside size and strength. Even genetically gifted athletes rarely escape it. If you want to build more muscle, you’re stuck with unwanted fat.

Not anymore! Now you have the freedom to build as much lean mass as you want, without the added fat — with Chosen 1.

Chosen 1 is Blackstone Labs’ premium muscle-builder, featuring a formula proven to boost size, strength, and aggression. Powered by 1-DHEA, Chosen 1 utilizes a unique precursor to 1-testosterone, a powerful testosterone derivative known for promoting lean, dry gains. Because 1-testosterone does not aromatize, Chosen 1 does not convert to estrogen, meaning no unnecessary water retention.

Advanced 3-Ester 1-DHEA System

Chosen 1 harnesses three forms of 1-DHEA:

• 1-Androstene-3β-ol,17-one

• 1-Androstene-3β-ol,17-one Undecanoate

• 1-Androstene-3β-ol,17-one Caprylate

Each ester peaks at different intervals, helping sustain elevated levels over time and deliver consistent anabolic support throughout the day.

Chosen 1 carries an anabolic-to-androgenic ratio of 1:2, supporting drier gains, little fat accumulation, and even better performance in the bedroom!

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.
