Blackstone Labs Metha-Quad EXTREME

Blackstone Labs Metha-Quad Extreme

Rapid increases in size. Greater strength and power output. Pumps and vascularity that would make Arnold jealous. These are real results from the most powerful designer prohormone stack Blackstone Labs has ever created: Metha-Quad Extreme.

Metha-Quad Extreme is an advanced 4-in-1 extreme muscle builder, engineered to deliver immediate lean gains alongside long-term density and mature muscle development. With built-in estrogen support, it allows you to push growth aggressively without sacrificing dryness or definition.

Some call Metha-Quad Extreme the most hardcore muscle builder on Earth because it combines four of the most effective muscle-building, testosterone-boosting compounds into one comprehensive formula.

The 4-Compound Anabolic System

Androsterone

A versatile prohormone that converts to dihydrotestosterone (DHT). DHT is known for supporting dense muscle development, strength, and a harder, drier physique.

1-Androstene-3β-ol,17-one (50 mg)

Also known as 1-Andro or 1-DHEA, this compound converts through a two-step process into 1-Testosterone, a potent testosterone derivative. Because it does not aromatize to estrogen, it promotes lean, dry gains with minimal fat accumulation during mass phases.

4-Androstene-3β-ol,17-one (50 mg)

Commonly referred to as 4-Andro or 4-DHEA, this compound converts directly into testosterone. Testosterone remains the primary anabolic hormone responsible for muscle size, strength, and performance output. 4-Andro may also stimulate appetite, supporting the caloric intake required during serious growth cycles.

Arimistane

A suicidal aromatase inhibitor that helps reduce circulating estrogen and cortisol levels by blocking the conversion of testosterone into estrogen. This supports higher testosterone availability while minimizing estrogen-related effects during the cycle.

Metha-Quad Extreme is fast acting and accelerates your muscle-building potential into overdrive, driving bigger, stronger, more powerful results every day.

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.
