Dr. Simeons was actually testing boys who were dealing with low testosterone using hcg injections when he noticed that they were losing tummy fat. That’s when he researched more upon hcg and how it works on the human body.
HCG is derived using pregnant women’s urine to treat infertility. Dr. ATW Simeons realised that it is this hCG hormone (on high level during pregnancy) that acts as a backup and helps the mother to nourish their unborn child.
The product probably might be derived from the urine of pregnant women in treating obesity.
