Building lean muscle isn’t just about lifting more — it’s about supporting the body’s anabolic environment with targeted inputs that promote efficient recovery, hormonal signaling, and cellular regeneration. Peptides offer a refined approach to supporting these outcomes.
Here are five clinically relevant peptides commonly used in structured protocols for lean mass development:
1. IGF-1 LR3
Insulin-like Growth Factor-1 LR3 is a long-acting analog of IGF-1. It supports muscle hypertrophy by stimulating satellite cell activation and enhancing protein synthesis. Due to its extended half-life, it remains active in the bloodstream longer, allowing for wider systemic impact.
2. CJC-1295 with DAC
This growth hormone-releasing hormone (GHRH) analog promotes a sustained increase in GH levels, which contributes to muscle tissue growth, recovery, and fat metabolism. With DAC, bioactivity is extended for more stable support.
3. Ipamorelin
Known for its clean profile, Ipamorelin is a growth hormone secretagogue that increases GH release without significantly affecting cortisol or prolactin. Its targeted action makes it ideal for protocols where lean mass is the goal and recovery must remain tightly controlled.
4. TB-500
Thymosin Beta-4’s synthetic counterpart supports cell migration, angiogenesis, and soft tissue repair. While not anabolic in the traditional sense, TB-500 accelerates recovery and creates a favorable environment for muscle development.
5. BPC-157
This gastric-derived peptide helps repair connective tissue and supports vascular flow. Its role in muscle development is indirect but vital, promoting durability, joint resilience, and systemic recovery — all critical for long-term lean mass retention.
Peptides from AlphaBoost are formulated and tested for purity, potency, and molecular identity. When used under proper guidance and within structured programs, these compounds support clean, measurable progress rooted in the body’s natural physiology.
