The Mass Builder Bundle (MBB) is a research-grade formulation composed of three potent anabolic and growth-modulating agents: 

  • 4X Blend (GHRP‑2, Tesamorelin, MGF, Ipamorelin): 

    • GHRP‑2 is a growth hormone secretagogue that binds to the ghrelin receptor, stimulating GH release via the pituitary [1]. 

    • Tesamorelin is a long-acting GHRH analogue designed to enhance GH pulsatility in preclinical models [2]. 

    • Mechano‑Growth Factor (MGF/IGF‑1Ec) is a splice variant of IGF‑1 that promotes localized tissue repair and muscle progenitor cell activation [3]. 

    • Ipamorelin is a selective GH secretagogue with minimal effect on prolactin or cortisol, supporting GH release [4]. 

  • Follistatin 344 (95%) is a 344-amino-acid glycoprotein that antagonizes myostatin and activin A, leading to increased muscle mass and improved tissue regeneration in animal studies [5][6]. 

  • IGF‑1 LR3 is a long-acting IGF‑1 analogue with enhanced receptor affinity and reduced binding to IGF‑binding proteins. Its extended half-life supports sustained stimulation of anabolic and growth-related signaling in muscle models [7]. 

Combined, this bundle enables comprehensive investigation into synergistic pathways of GH induction, localized IGF signaling, myostatin inhibition, and systemic anabolic stimulation for muscle growth and protein synthesis research. 

This bundle is intended for laboratory research purposes only.
