Fertigyn (Pregnyl)

Manufacturer – Sun Pharmaceuticals

Drug form – 1 vial of 5000 IU

Active ingredient – Human Chorionic Gonadotrophin (HCG)

Pharmacological action

Human Chorionic Gonadotrophin is a drug that includes a hormone that is produced during pregnancy by the placenta. The properties of Fertigyn (Pregnyl) are almost identical to the properties of the luteinizing hormone (gonadotropin), which is usually produced in the pituitary gland.

Positive qualities of the drug:

o Stimulates the synthesis of sex hormones in the testicles in men (a similar spectrum of effects with testosterone)

o Activates spermatogenesis

o Strongly contributes to the development of primary as well as secondary sexual characteristics

o Develops male genitalia

o In women, it supports the development of the placenta and stimulates the production of progesterone

Gonadotropin is particularly popular among bodybuilders due to its property of increasing testosterone. It is because of the ability to increase the secretion of the genitals, athletes can take Gonadotropin as an anabolic drug, which has a direct effect on the growth of muscle mass. Often, Fertigyn (Gonadotropin) is used for weight loss as an auxiliary tool, as well as for post-course therapy (PCT).

The reason for use

Fertigyn (Gonadotropin) in PCT is associated with the fact that, in the male body, the process of regulation of Gonadotropin occurs as follows: hypothalamus – pituitary – testicles. In other words, gonadoliberin is produced in the hypothalamus, which generates an effect that causes the release of gonadotropin. It is no secret that athletes often have cases of a lack of this hormone due to the fact that the impact on the hormone of anabolic steroids has a “inhibitory” effect on the athlete’s body. With such a lack of hormone, there is a risk of testicular atrophy.

Dosages and intake

In order to dilute the Fertigyn, use a solvent, that is “sodium chloride solution for injections 0.9%”, which can be purchased at a pharmacy without a prescription.

In terms of exposure, the drug is quite long. Due to the high rates of absorption, the drug acts for 5-6 days. The recommended dose of the drug, if it is necessary to achieve an anabolic effect, is 5000 IU per week. You should inject the drug once a week to achieve maximum results. If you reduce the dose and take the drug more often, it will most likely not have the desired effect.

In post-cycle therapy, the dose of Fertigyn depends on the duration of the steroid course.

o If the course of taking steroids exceeds 4 weeks and the number of drugs that are taken is more than two, the recommended dose of gonadotropin is 500-100 IU twice a week.

o If the steroid course is less than 4 weeks and 1-2 drugs are taken, the intake of Gonadotropin is not necessary. Its dose may be minimal or, in general, there is no need to take it.

o Fertigyn is used as a weight loss drug at a dose of 1000 IU per week

Combination with other drugs

As for the combinations of Fertigyn with other drugs, the combination of the drug with Clomid is widely popular among athletes. For a quick recovery of endogenous testosterone, it is recommended to take Clomid after the use Fertigyn.

You can buy Clomid for PCT (Post Cycle Therapy) from our online store and find out the recommendations for taking it on the product page.

It should be noted that this combination is effective only at the end of a course of taking steroids and is not advisable at the beginning or in the middle of the course.

Side effects of gonadotropin and intake by women

As a rule, Fertigyn (gonadotropin) is rarely taken by women, although there are cases when they take this drug in preparation for competitions.

Side effects with the adherence to the correct dosages are practically not manifested. The phenomena that may occur after taking the drug are the same as when taking drugs containing testosterone.

o Rash

o Severe sweating

o Slight hair loss

The only negative manifestation of the drug is considered to be an increased aromatization of Gonadotropin (Fertigyn), but this property cannot be explicitly attributed to negative effects. There is a misconception that when taking the drug, men may experience symptoms that occur during pregnancy. These rumors should not be trusted, as the opinion is false.
