Lift Free And Diet Hard with Andrew Coates #414 Dr. Dwayne N. Jackson – Peptides and GLP-1 Agonist Drugs Masterclass
Nov 6, 2025
Dr. Dwayne N. Jackson, a peptide researcher and expert in neuromuscular physiology, discusses the complexities of peptides and GLP-1 agonists. He breaks down what peptides are and addresses the hype around BPC-157’s healing claims. Dwayne emphasizes the risks of sourcing peptides unsupervised and highlights the emerging potential of GLP-1 drugs for weight loss and appetite management. He warns of social media misinformation affecting health decisions and stresses the importance of regulated use in bodybuilding, exploring the implications for athletes.

Other Peptides With Real Mechanisms
- Several peptide classes show promise: GHRH/ghrelin analogs raise GH/IGF-1, and mitochondrial peptides (SS31, MOTS‑c) impact cellular energetics.
- Human trials vary, but mechanism-based effects are plausible and measurable.
Why GLP‑1s Move The Needle
- GLP‑1 and related multi-agonists (semaglutide, tirzepatide, retatrutide) dramatically reduce appetite and improve metabolic markers.
- Their main clinical value is robust, often linear, fat mass reductions driven by satiety and glucose effects.
Protect Muscle While Losing Fast
- While on GLP‑1 drugs, plan meals to preserve lean mass: ensure enough protein, carbs, fats and resistance training.
- Monitor weight-loss rate to avoid excessive lean-mass loss during rapid fat reduction.
