Pregnyl 1500 IU (Human Chorionic Gonadotropin) – 3 Pack

Pregnyl 1500 IU is an injectable hormonal medication containing Human Chorionic Gonadotropin (hCG). Manufactured by Organon, this product provides 3 separate vials, each containing 1500 IU of hCG.

It is a prescription therapy used to induce ovulation in women undergoing fertility treatments and to treat hypogonadism (low testosterone) in men. It is also a staple “off-label” compound for male Post-Cycle Therapy (PCT) to restore natural hormonal function.

Product Overview: Pregnyl 1500 IU (hCG)

Pregnyl 1500 IU is a purified form of hCG, a glycoprotein hormone that mimics the body’s natural Luteinizing Hormone (LH). Because it can “impersonate” LH, it is a versatile therapeutic agent for both sexes.

This product is supplied in 3 individual sets, each containing one vial of 1500 IU lyophilized (freeze-dried) powder and one ampoule of sterile solvent. The 1500 IU dosage is a common, flexible dose used for smaller, more frequent injection protocols.

How Does Pregnyl 1500 IU (hCG) Work?

Pregnyl works by binding to and activating the same receptors as Luteinizing Hormone (LH).

• In Women (Fertility): hCG is famously used as the “trigger shot.” After follicle-stimulating hormones have prepared the ovaries, an injection of Pregnyl mimics the natural LH surge, providing the final signal for the mature eggs to be released (ovulation).
• In Men (Hypogonadism & PCT): In the male body, LH signals the testes (Leydig cells) to produce testosterone. By mimicking this LH signal, Pregnyl 1500 IU directly stimulates the testes, helping to restart or increase natural testosterone production and maintain testicular size, especially after it has been suppressed by anabolic steroid use.

Key Product Details

Dosage and Administration

Pregnyl 1500 IU must be prepared (reconstituted) immediately before use.

1. Reconstitution: Dissolve the 1500 IU powder by adding the entire contents of one solvent (diluent) ampoule. Mix gently by swirling; do not shake the vial. 2. Administration: Draw the mixed solution into a syringe. It is administered as either an intramuscular (IM) (deep into a muscle) or subcutaneous (sub-Q) (under the skin) injection.

Dosage protocols are determined by a physician:

• For Female Ovulation: Doses vary; 1500 IU may be used in specific protocols, or multiple vials may be combined for a larger single “trigger shot” (e.g., 4500-5000 IU).
• For Male Hypogonadism/PCT: The 1500 IU dose is often split. A common protocol might be 500 IU injected 3 times per week.

Important: This is a prescription-only medication. You must follow the exact instructions for mixing, storing, and injecting provided by your healthcare provider.

Frequently Asked Questions (FAQ) about Pregnyl 1500 IU

How do I store the mixed (reconstituted) Pregnyl?

Before mixing, the vials can be stored at room temperature. After you have mixed the powder and solvent, the solution is no longer stable and must be stored in a refrigerator (between 2°C and 8°C). It must typically be used within 30-60 days (check the product insert).

What is the difference between hCG (Pregnyl) and SERMs (like Klomen/Tamoxifen)?

They work at different points in the hormonal axis.

• hCG (Pregnyl): Works directly on the testes (mimics LH) to produce testosterone.
• SERMs (Klomen/Tamoxifen): Work on the pituitary gland in the brain, blocking estrogen’s negative feedback to help the body produce its own LH.

Is Pregnyl (hCG) a steroid?

No. It is a peptide hormone, not an anabolic-androgenic steroid (AAS). It is used to counteract the side effects of steroids.

Can men get side effects from hCG?

Yes. By stimulating the testes to produce more testosterone, hCG can also increase the conversion of that testosterone into estrogen. This means it can potentially cause or worsen estrogenic side effects (like gynecomastia or water retention) if not used carefully, often in conjunction with an aromatase inhibitor.

Important Safety Information

Warning: Pregnyl is a potent hormone and must be used under strict medical supervision.

For Women: When used for fertility, hCG carries a risk of Ovarian Hyperstimulation Syndrome (OHSS), a rare but serious condition. For Men: Do not use Pregnyl if you have a history of prostate cancer or certain other hormone-sensitive cancers.

Do not take Pregnyl if you are allergic to hCG or if you are pregnant (unless specifically used as a “trigger shot” in a fertility protocol).
