HCG(human chorionic gonadotropin) is sometimes referred to as the "pregnancy hormone" because of its important role in maintaining pregnancy, and it is pregnancy tests that measure HCG levels in urine or blood to determine whether they are positive or negative.
HCG injections are also approved by the US Food and Drug Administration (FDA) for the treatment of specific medical conditions in women and men.
In women, HCG is fDA-approved to help treat infertility; In men, HCG is fDA-approved to treat a form of hypogonadism (when the body does not sufficiently stimulate the gonads to produce the sex hormone testosterone)
In men, doctors use HCG to combat symptoms of hypogonadism, such as testosterone deficiency (blood levels below 300 nanograms per deciliter) or low testosterone and infertility, and it can help users increase testosterone, sperm production and thus reduce infertility.
For the bodybuilding community, its main use is to maintain, increase or restore appropriate levels of endogenous testosterone.
HCG is best used in conjunction with other testosterone-producing stimulants during PCT, and the use of HCG alone as a hormone restorer after the cycle is outdated and pre-1990.
Understanding of HCG and all other drugs has improved dramatically since bodybuilders used anabolic steroids in the 1960s, '70s and' 80s.
In fact, from the 1960s to the mid-1980s, most anabolic steroid users didn't even use any compounds for endogenous hormone recovery, and PCT didn't even exist at the time.
When the use of HCG became more and more popular (circa 1980), it was the only compound used.
Since then, the medical and scientific understanding of these things has grown exponentially, and there is no reason for any informed and properly educated individual to use HCG to implement PCT himself.
HCG has been abused by some members of the public for weight loss purposes, which is actually very dangerous and can cause permanent damage to Leydig cells in the testes.
HCG use has been shown to increase aromatase activity in the body by increasing the expression of testicular aromatase, an enzyme responsible for converting androgens into estrogens, so the result of HCG use is an increase in estrogen levels in addition to testosterone stimulation.
Therefore, aromatase inhibitors are essential in the use of HCG
