Vesugen is only three amino acids long: lysine, glutamate, and aspartate — KED. Yet it is promoted as a vascular bioregulator that may support endothelial health and even "rejuvenate" aging blood vessels.
In this episode, John Garrett looks at what the endothelial research actually measured, the p…
FLGR-242 is being called a smarter, longer-acting follistatin. John examines the advertised construct, the activin-sparing and 19-day half-life claims, the difference between pathway evidence and product evidence, and why transformation photos cannot establish pharmacology or safety.
Follistatin can bind myostatin—one of the body's major restraints on skeletal-muscle growth. Animal studies are dramatic, and small human gene-therapy studies have produced encouraging signals in serious muscle disease.
But is a vial labeled "Follistatin-344" equivalent to the therapy used in thos…
Glutathione gets called the "master antioxidant," and the underlying biology really is important. But does that mean oral supplements, liposomal products or glutathione IVs deliver the sweeping detox, energy, immune and anti-aging benefits often attached to them?
