What is HCG (Human Chorionic Gonadotrophin)?

Pregnyl 5000iu is a pharmaceutical-grade HCG injection made by Organon. It's a natural hormone that mimics LH (luteinising hormone) in the body. It was originally developed to treat fertility issues in both men and women.

Quick Facts

How Does It Work?

HCG binds to the same receptors as LH in the testes. This signals the testes to produce testosterone and maintain their normal size and function. During or after a steroid cycle, this helps keep natural testosterone production from shutting down completely.

What It's Used For

• Preventing testicular atrophy during an anabolic steroid cycle
• Kickstarting natural testosterone production as part of PCT
• Treating hypogonadism and male fertility issues medically

What to Expect

Most men notice an improvement in testicular size and fullness when using HCG during a long cycle. It helps bring natural testosterone levels back up faster after a cycle ends. It works best when used as a bridge before starting a full PCT protocol.

Possible Side Effects

• Water retention and bloating at higher doses
• Increased oestrogen levels, which can cause gynecomastia
• Desensitisation of LH receptors if used too long or at very high doses

Cycle & Dosage Notes

A common approach is 500iu twice a week throughout a cycle to keep the testes active. For post-cycle use, many run 2500iu every other day for two weeks before starting SERMs like Nolvadex or Clomid. Avoid running HCG for extended periods without a break, as this can blunt your natural LH response.

Storage

Keep at room temperature (15–25°C), away from light and moisture. Leave in the original packaging.
