Comprehensive Lean Muscle & Performance Stack
The VST Research Labs Lean Mass Bundle is an advanced research‑oriented stack designed to support investigations into **lean muscle development, strength signalling, anabolic pathways, and recovery mechanisms** in controlled experimental settings. This bundle combines multiple compounds frequently studied together to explore synergistic effects on body composition and performance.
Main Research Benefits of the Lean Mass Bundle
- Supports lean muscle growth signalling and anabolic pathways
- May help investigate strength performance and hypertrophy mechanisms
- Facilitates exploration of recovery, protein synthesis, and regenerative signalling
- Combines complementary mechanisms to support body composition research
- Ideal for multi‑compound protocols in laboratory studies
How This Bundle Works
The Lean Mass Bundle is formulated to encompass several research compounds that target different physiological systems. Typically, such lean mass stacks include **selective androgen receptor modulators (SARMs)** and **growth hormone secretagogues** to support muscle‑related signalling, protein synthesis, and recovery pathways. Researchers use stacks like this to evaluate the combined impact of anabolic receptor activation, metabolic signalling, and endocrine regulation on lean tissue dynamics.
Although exact ingredients may vary, lean mass bundles commonly include compounds such as:
- RAD140 (Testolone): A potent SARM known for its anabolic signalling in muscle and bone pathways.
- MK677 (Ibutamoren): A growth hormone secretagogue that stimulates GH & IGF‑1 pathways.
- LGD4033 (Ligandrol): A SARM studied for supporting lean tissue and strength signalling.
When studied together, these compounds allow a broader view of **lean muscle support, recovery and metabolic modulation** than single‑compound research alone.
Suggested Research Usage
In laboratory or controlled research protocols, lean mass stacks are typically administered daily according to experimental design to maintain stable engagement of anabolic and growth pathways throughout the research period. Consistent dosing supports sustained signalling across the stack’s targets, making it useful for studies on muscle hypertrophy and performance.
⚠️ Important: The VST Research Labs Lean Mass Bundle is intended strictly for research and laboratory investigation. It is **not approved as a dietary supplement, therapeutic drug, or for human or veterinary consumption**. Follow all applicable legal guidelines and laboratory safety protocols.
Who Is This Bundle Best Suited For?
This bundle is ideal for advanced researchers and scientists exploring the interaction between multiple pathways involved in **lean tissue growth, strength performance, recovery signalling, and metabolic regulation**. It is particularly useful in experimental settings where the effects of combined compound protocols are being investigated.
