Human growth hormone, or HGH, is a common hormone the body produces. However, recombinant HGH has been developed, and people use it to increase their HGH levels. But the question is, who invented HGH? Read more to find out.
Human growth hormone (HGH) is naturally secreted and regulated by the pituitary gland, but the one discovering the HGH synthesis was Choh Hao Li with helps from his fellow scientists, mainly Cyril Norman Hugh Long (1901 – 1970) and Abraham White (1908 – 1980), the two of whom had previously succeeded in isolating prolactin extracted from cattle in pure crystalline form in 1937 and in 1943 along with George Sayers, porcine adrenocorticotropic hormone (ACTH) which had been purified beforehand.
The invention of HGH has greatly contributed to the biochemistry and molecular endocrinology fields and HGH treatment.
HGH treatment has become an important tool for treating various medical conditions, including growth hormone deficiency,
Turner syndrome, and chronic kidney disease. HGH therapy has also been used off-label for a variety of other purposes, such as anti-aging and athletic performance enhancement.
Li was born on April 21, 1913, in Guangzhou. His parents were incredibly strict to him and his 13 siblings when it came to education.
He had earned his Bachelor of Science degree at Nanking University, where he used to work as a chemistry lecturer for 2 years before he decided to immigrate to the US in 1935.
He studied organic chemistry at the University of California, Berkeley, and earned a Ph.D. there in 1938. Li had endured great hardship from the anti-Asian sentiment during the Depression Era for some time until he began to make a breakthrough for his future career when Herbert Evans allowed him to get a job related to the study of endocrinology of the pituitary gland at the Berkeley Institute for Experimental Biology.
He established the Berkeley Hormone Research Laboratory in 1950.
Li began his research on growth hormone by isolating it from the pituitary glands of rats. He then turned his attention to human growth hormone, which had never been isolated before.
The challenge was to obtain enough human pituitary glands to conduct the necessary experiments.
Li contacted hospitals and morgues across the country and was able to collect a sufficient number of pituitary glands from deceased donors. He then used a variety of techniques, including chromatography and electrophoresis, to isolate and purify human growth hormone.
In 1944, he announced his discovery of human growth hormone in the journal Science. The discovery was groundbreaking, as it allowed scientists to study the effects of growth hormone on the human body and led to the development of treatments for growth disorders such as dwarfism.
Li completely managed to isolate HGH in 1955 and synthesize it in 1971. His work in isolating and synthesizing human growth hormone (HGH) was a significant milestone in the field of endocrinology, leading to a better understanding of the role of hormones in human development and growth. Throughout his life, he worked as a biochemist and an endocrinologist focusing on HGH and several other important hormones including luteinizing hormone, beta-endorphin, follicle-stimulating hormone, thyrotropin, prolactin, melanocyte-stimulating hormone, and lipotropin.
Also Li’s work paved the way for further research in these areas and has had a profound impact on the field of endocrinology, leading to the development of new treatments for a wide range of conditions related to hormone imbalances.
His legacy continues to inspire and inform the work of scientists and researchers in this field today.
In addition to his work on growth hormone, Li made many other important contributions to the field of endocrinology. He was the first to discover the hormone thyrotropin-releasing hormone (TRH), which regulates the production of thyroid-stimulating hormone (TSH).
He also developed techniques for synthesizing hormones, including insulin and parathyroid hormone, which revolutionized the field of hormone research.
Li was also known for his generosity and kindness. He was known to go out of his way to help his colleagues and students, and was always willing to share his knowledge and expertise.
He was also a strong advocate for diversity and inclusion in the scientific community, and worked to promote opportunities for underrepresented groups.
Li's contributions to the field of endocrinology were widely recognized during his lifetime.
He had also received and/or been nominated a lot of scientific awards such as the prestigious Albert Lasker Award for Basic Medical Research in 1982, the Wolf Prize in Medicine in 1985 (including Nobel Prize at least twice), the National Medal of Science, the highest scientific honor in the United States.
In addition, he received the honor of being elected to both the National Academy of Sciences and the American Academy of Arts and Sciences.
He also published around 1,100 scientific journals, many of which were groundbreaking in their field and secured several important positions related to his work fields.
He was a professor at the University of California, San Francisco, and served as director of the Laboratory of Molecular Endocrinology at the university's medical center.
He was also a member of the National Academy of Sciences and served on the editorial boards of numerous scientific journals.
He eventually succumbed to cancer on November 28, 1987, survived by his wife and their three children. He believed in nurturing individual talent and creativity, and often pushed his students to think beyond the conventional and take risks in their research.
Many of his former students went on to have successful careers in academia and industry, and credit Li with inspiring and guiding them in their work.
He was renowned for his open-minded teaching methods and encouragement for his students to be as creative and independent as possible.

Belly Fat Affects HGH Production - 1 Way To Reduce Belly FatConsume curcuminCurcumin is the active component found in the golden spice called turmeric. Turmeric is considered as a super spice due to its curcumin content that has many health benefits. Recent studies have tried to look into the correlation between curcumin and weight loss and the results are quite promising. Curcumin actually has anti-inflammatory properties. Research has shown that this ability can suppress the building of fat tissues, making it harder for your body to gain weight from the fats that you consume. It needs to be noted that in order for curcumin to work its magic it needs to be ‘activated’ by black pepper. That is why it is recommended to consume turmeric with black pepper. Black pepper also promotes better absorption of this substance by the body. Many Indian cuisines use turmeric and black pepper, but if you are looking to lose some weight you need to also watch out for the amount of oil used in many Indian dishes. |
