Despite the rampant use of intravenous glutathione injections for skin lightening in certain countries, evidence favoring such a practice remains elusive
Conclusion Conclusion Cystathionine-beta-synthase is a key connection between sulfur containing amino acids, an antioxidant function and the signaling molecule hydrogen sulfide
What IGF-1 LR3 does Muscle & Strength Increases muscle protein synthesis Supports muscle hypertrophy (fiber growth) May promote muscle hyperplasia (new muscle cell formation a key distinction vs many other compounds) Improves nutrient shuttling (glucose, amino acids into muscle) Result: Greater lean mass potential and fuller muscles Recovery & Tissue Repair Accelerates muscle repair after intense training Supports connective tissue, tendon, and ligament healing Enhances cell regeneration after injury or stress Result: Faster recovery and reduced downtime Fat Metabolism & Nutrient Partitioning Improves nutrient partitioning (calories are more likely used for muscle vs fat) Can indirectly support fat loss when paired with training Enhances insulin-like activity at muscle cells Result: Leaner body composition over time Cellular Growth & Anti-Catabolism Strong anti-catabolic effects (prevents muscle breakdown) Promotes cell survival and growth signaling Supports regeneration in multiple tissue types Result: Preservation of muscle during intense training or calorie deficits Blood Sugar Effects (Important) Because IGF-1 LR3 mimics insulin: It lowers blood glucose Can increase hypoglycemia risk, especially without adequate nutrition Result: Powerful effects, but requires careful control in research contexts
A different study using the same dose showed increases in lipid oxidation and lipolysis which contribute to a decrease in adiposity and may make more nutrients available to muscle (Krag, Gormsen, Guo et al., 2007)
It can be used in clinician-led plans where sleep is one part of a bigger goal set
