This hormonal cascade works as follows: The hypothalamus releases gonadotropin-releasing hormone (GnRH) GnRH signals the anterior pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH) LH stimulates the Leydig cells to produce testosterone Rising testosterone feeds back to the hypothalamus and pituitary to regulate production (negative feedback loop) Testosterone is responsible for: Muscle protein synthesis and lean body mass maintenance Bone mineral density Red blood cell production Libido and sexual function Energy, mood, and cognitive function Fat distribution and metabolic health Normal total testosterone in adult men ranges from approximately 300 to 1,000 ng/dL, with levels declining by roughly 1 to 2 percent per year after age 30 (Harman et al., 2001)

BPC 157 offers numerous clinical benefits for individuals recovering from injuries: Speeds up recovery : BPC 157 has been shown to significantly accelerate recovery from various injuries, including tendon and ligament damage
EGFR is a similar tyrosine kinase receptor as c-MET has been reported to be highly expressed in 90% of the HNSCC patients
Through continuous monitoring of synaptic activity, microglia selectively preserve or eliminate synapses based on their functional relevance (158), thereby enabling dynamic synaptic remodeling that supports essential cognitive processes such as learning, memory, and behavioral adaptation (169, 170)
However, the relationships between mitochondria and synapses, and the role of mitochondria in the pathogenic mechanisms of these syndromes have yet to be established
