However, this is not the case—testosterone remains one of […]

Currently, GLP-1 therapies dominate the weight-loss drug market, achieving 20%–25% weight reduction within a year while continually pushing the upper limits of weight loss.

IGF-1 is not an anabolic steroid but a protein hormone (also known as a peptide or simply a peptide hormone), structurally highly similar to the hormone insulin—another peptide/protein hormone. IGF-1 is primarily produced and synthesized naturally within the human body, mainly in the liver. The liver is stimulated by human growth hormone (HGH) to trigger

Sermorelin (growth hormone-releasing factor) is a synthetic peptide hormone. Upon binding to receptors on the surface of pituitary cells, Sermorelin promotes the release of growth hormone, enhances fat metabolism, and inhibits the breakdown of insulin-like growth factor (IGF-1). This process increases the efficiency of muscle protein synthesis. This promotes muscle synthesis, reduces fat accumulation, and

A study published in the Journal of the Optical Society of America reveals that under identical sun exposure and during the natural aging process, collagen loss in women’s skin occurs at a faster rate than in men’s skin[1]! Collagen, a crucial protein found in the dermis, acts like a “spring” to maintain skin elasticity. However,
