Lean Mass Stack Prohormones

The Lean Mass Stack is built for serious lifters who want dry, lean muscle and hard strength gains without bloating or oestrogenic spillover. It combines Nano 1T, a nanoparticulated form of 1-Testosterone that is 700% more anabolic than testosterone with no conversion to oestrogen, and Halodrol, a mild, highly anabolic compound known for producing clean, aesthetic muscle gains with minimal side effects. Together, they form an advanced lean recomposition stack, delivering exceptional increases in muscle density, strength, and hardness — the kind of “contest prep” quality muscle that stays dry, defined, and strong

The Lean Mass Stack is best used during lean bulking or recomposition cycles — phases where users aim to increase muscle tissue while staying defined. Both compounds should be used for 4–8 weeks, followed by a complete post-cycle therapy (PCT) to restore hormonal balance. We recommend using Cycle Guard Elite for on-cycle support and a TUDCA-based liver formula if stacking other methylated compounds. Due to its dry nature and non-oestrogenic action, this stack is perfect before photoshoots, competitions, or summer phases where definition matters as much as mass.

This stack is for advanced male athletes over 21 who have maximised their natural gains and want to achieve a dense, powerful, and aesthetic physique. Nano 1T offers next-level anabolism through nanoparticulated delivery, while Halodrol provides a controllable, lean mass-building effect suited to users newer to prohormones. It’s not suitable for beginners, women, or tested athletes, and should only be run by those familiar with cycle protocols and post-cycle recovery.
