The Future of Muscle Growth Drugs

Jun 4, 2025

Lecture on Non-Androgenic Anabolic Drugs

Introduction

  • Discussion on the potential of new drugs that greatly enhance muscle gains without traditional steroid side effects.
  • Emphasis on modern pharmaceuticals revolutionizing body composition enhancement.

Traditional Steroids vs. New Drugs

  • Steroids: Cause muscle growth along with androgenic side effects like hair loss, acne, aggression, etc.
  • New Drugs: Aim to increase muscle mass without these side effects.

Key Drugs Discussed

  • Travagramab: A myostatin antagonist.
  • Gerrettmab: An Actin A antagonist.
  • Function: Both reduce myostatin and Actin A activity, which limit muscle growth.

Research Study Overview

  • Conducted by Regeneron Pharmaceuticals on non-human primates.
  • Four groups:
    1. Diet-only monkeys.
    2. Monkeys on Semaglutide (a weight loss drug).
    3. Monkeys on Myostatin blocker.
    4. Monkeys on both Myostatin and Actin A blockers.

Study Findings

  • Diet-only Group: Lost 400g of fat, 15g of muscle.
  • Semaglutide Group: Lost 700g of fat, but 100g of muscle.
  • Myostatin Blocker Group: Lost 1300g of fat, minimal muscle loss.
  • Combo Therapy Group: Lost 1400g of fat, gained 450g of muscle.

Implications for Humans

  • Potential Human Applications: Drugs likely transferable to humans as trials are ongoing.
  • Expected Effects: Major fat loss, increased muscle gain without androgenic side effects.
  • Potential Market Release: Around 2027-2028 after FDA approval.

Broader Implications

  • Impact on Steroid Use: Could replace steroids due to fewer side effects and better results.
  • Body Composition Revolution: Allows for targeted muscle growth and aesthetic enhancement.
  • Health Benefits: Increased muscle mass linked to numerous health improvements.

Conclusion

  • Anticipation of a major shift in body composition and fitness industry.
  • Encouragement to avoid steroids in favor of these upcoming drugs.
  • The potential for a renaissance in physique sports and personal fitness.
