HCG Driada Medical (Human chorionic gonadotropin)


HCG Driada Medical (Human chorionic gonadotropin) is a polypeptide hormone that contains an alpha sub-unit that is similar to the alpha components of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH) and a beta sub-unit that has a different amino acid sequence.

This means that HCG Driada Medical (Human chorionic gonadotropin) exerts nearly identical effects as LH in activating the production of gonadal steroid hormones to produce androgens and progesterone and in influencing the development of male secondary sex characteristics and in normal menstrual cycle for women, but it has a weak FSH activity. It sustains the corpus luteum during pregnancy.

HCG Driada Medical (Human chorionic gonadotropin) and other gonadotropins are synthesized in the body and are not xenobiotics, so allergic reactions are rare. Chorionic gonadotropin is a hormone that is produced by the placenta during pregnancy and then excreted unchanged in the urine, from where it is extracted and purified to obtain drugs.

HCG Driada Medical is FDA approved drug with proven efficiency.

There are a few major issues that require HCG Driada Medical (Human chorionic gonadotropin) as a tool. Let’s consider the one – most interested for the athletes and people on TRT.

During the steroid cycle or testosterone replacement therapy(TRT), the use of exogenous testosterone suppresses the release of LH from the brain.

Exogenous Testosterone halts the Hypothalamic–pituitary–gonadal axis (HPTA) is ceased and the testicles are no longer receiving LH. This is known by most of us as simply “shutdown” or “HPTA suppression“ or Testicular Atrophy.

Men will see their testicles get smaller over time and hurt constantly along the way, sperm production is pretty much halted also. The duration for this event seems to be different in men where younger guys can seem to go longer, whereas mid to older guys see the event happening on a more accelerated scale. Scientists think that it happens to do with the number of receptors on the Leydig cells, but there is no research to prove it for sure.

Men’s scrotum will get really tight and pull up causing pain and end up looking like a 6-year-old, meanwhile, the sperm quality becomes really bad and these changes may be irreversible.

Due to this action testosterone monotherapy has been investigated as a male contraceptive [1,2,3]

In the body, the regulation of gonadotropin levels occurs by a feedback mechanism in the hypothalamus-pituitary-testes axis, so gonadotropins are produced in the pituitary gland and normally stimulate the work of the testicles, but with their deficiency, testicular atrophy occurs.

In order to escape testicular atrophy it’s very important to support testicular activity during the cycle/TRT. And HCG treatment is a major tool for this.

The suppression of luteinizing hormone, which maintains (stimulates) the normal function of the testicles after a 12-16 week cycle, causes the decrease of the volume of Leydig cells by 90%, and the secretion of own testosterone by 98% , but Leydig cells make up only about 5% of the mass of the testis, so testicular size is not an indicator of suppression level, since the volume can change very little (only 5%) with almost complete suppression of Leydig cells function.

HCG Driada Medical 2.000 IU Dosage

There are dozens of HCG protocols, but these schemes are recognized as optimal since it allows you to save the function of the testicles and contributes to the most complete recovery after the AAS cycle:

·If the duration of the cycle does not exceed 5-12 weeks, and drugs are used in small\moderate doses for at least the last 3-5 weeks of the cycle, make 2 injections of gonadotropin per week, 250-500 IU, to prevent testicular atrophy.

·On long multi-month cycles, gonadotropin is used as described above continuously, 3-5 weeks on, 1-2 weeks off (it is necessary to take a break for at least 1-2 weeks in order to prevent desensitization).

·If hCG has not been used during the long n heavy cycle, then it should be included in the post-cycle therapy, but then it should be used only at the beginning of PCT. The most commonly used protocol according to William Llewellyns is supported by clinical trials [4]. hCG is recommended to be used as part of post-cycle therapy of 2000 IU, every other day for 20 days to restart the HPTA. But large doses (2000-5000 IU) are not recommended for longer than 20 days.

Human chorionic gonadotropin during the TRT:

·Once a Week Testosterone Injection Protocols

If a man injects Testosterone on a once a week basis the more common protocol is to use 250IU of hCG two days before and one day before their next testosterone injection. The theory here is that Testosterone serum levels are at near half-life and the injection of hCG on these days increases natural production creating a bridge until the next testosterone injection.

·Twice a Week Testosterone Injections

If a man injects twice a week similar to an every 3-5 day schedule, use a more common protocol: smaller doses applied more frequently.

Inject 250IU of hCG on an EOD basis or on a Monday-Wednesday-Friday protocol.

·Cream or Gel Daily Use

If a man uses a Cream and/or Gel some of the top Testosterone Replacement Physicians, like Dr. John Crisler, recommend patients use 100iu of hCG every day.

Note: It’s not advisable to inject more than 500iu’s of hCG in any 24-hour period as it can increase intratesticular E2 which an AI is largely ineffective in controlling.

Additionally, there is a hypothesis that large amounts of hCG may desensitize the receptors on the Lydeg cells. Also, according to Michael Scally, M.D. and studies [5], testicular desensitization does not occur if the dosage does not exceed 500 IU per injection and hCG is injected less than 3 times a week.

Also, large doses cause rapid estrogen rise, so in order to avoid it, aromatase inhibitors will not work, because intratesticular aromatization will take place, so use tamoxifen or divide the weekly HCG dose into smaller parts. [6]

Storage, Preparation & Viability

Unmixed / unconstituted HCG powder must be stored in the refrigerator, but it can be stored for more than a month in a dark place, below +25 degrees Celsius, without any degradation.

HCG usually comes with a saline solvent, which is only suitable for use when the HCG is being administered as a single, one-off dose (usually in fertility treatment).  If you are multi-dosing your HCG for use in TRT, the saline solvent that it comes with MUST be discarded and substituted for bacteriostatic saline. Bacteriostatic saline contains a preservative which inhibits the growth of bacteria, thereby prolonging your HCG’s shelf-life.

Once mixed / constituted, all HCG should be stored in the refrigerator and used within 30 days.  HCG is an extremely fragile substance and exposure to light and heat will cause it to degrade.

Human chorionic gonadotropin Injections

Injections could be made subcutaneously and intramuscularly with an insulin syringe.

Disinfect the rubber cap of the drug and the injection site with alcohol.

Draw the drug into a syringe and inject it slowly.

HCG Driada Medical Pharmacodynamics

The half-life of HCG is several hours, but the effect lasts for 5-6 days reducing slowly.

Is HCG Safe?

An international consensus statement from 2005 concluded that urinary-derived HCG appears to be safe


In addition, HCG Driada Medical administration increases the ovarian response to gonadotropins in hypopituitary- or growth-hormone–deficient subjects.

Yet, supplemental GH does not appear to have dramatic effects on gonadotropin action in individuals with normal pituitary function.

It was a simple and manual-like article about HCG and its necessity for everyone who uses the exogenous testosterone and its derivates.
