In 1935, testosterone became the first anabolic steroid ever synthesized, extracted from bull testicles. Testosterone later entered the market in the 1950s through the pharmaceutical company Upjohn. It is commonly believed that as time passes, technology and knowledge advance; consequently, the potency of “supplements” evolves accordingly. 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. However, research indicates that approximately 30-40% of weight loss from GLP-1 drugs like semaglutide stems from muscle loss. This may lead to reduced metabolic rates and increased risk of weight regain.

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

I’ve always been a chubby girl since childhood. To lose weight, I’ve tried every method under the sun. Every year, I’m on this weight-loss journey, and my blood sugar has become increasingly unstable. After getting checked at the hospital, the doctor suggested I try tirzepatide. Today is my first day injecting tirzepatide, at a dose

IntroductionWeight management is a key component of overall health. Being overweight or obese is more than just a matter of appearance; it’s a condition that significantly increases the risk of chronic disease. This information sheet provides an overview of three medicines designed to help with weight loss and improve related health conditions—Tirzepatide, Semaglutide, and Retatrutide.

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,

As early as 2022, the world’s richest man, Elon Musk, publicly responded to netizens’ inquiries about his weight loss secrets: fasting and Wegovy. He claimed to take a weekly semaglutide injection and stated that addressing obesity can significantly reduce the risk of other diseases and improve quality of life. He said nothing can improve Americans’

I previously introduced semaglutide, the “miracle weight loss drug” used by Elon Musk. Two years have passed, and much has changed. For example, a domestically available injectable version for weight loss has been launched, and an oral version for the treatment of type 2 diabetes has been approved. Besides semaglutide, you’ve undoubtedly heard of numerous
