ACTIVE SUBSTANCE
Human Chorionic Gonadotropin
Introducing Pregnyl 5000 IU, an injectable medication crafted by MSD, featuring Human Chorionic Gonadotropin (hCG) as its key ingredient. This vital hormone, naturally produced during pregnancy by the developing placenta, plays a crucial role in appetite regulation and encourages the conversion of fat into energy. Beyond its role in fertility treatments?inducing ovulation in women and boosting sperm production in men?hCG is a favorite among bodybuilders, especially during steroid cycles and post-cycle therapy, to preserve muscle mass and stimulate testosterone levels.
Pregnyl is particularly beneficial for athletes finishing an anabolic-androgenic steroid cycle, as it helps prevent muscle breakdown and restores normal testicular function. Long-term steroid use can lead to testicular shrinkage, but Pregnyl effectively helps revert them to their natural size. Coupled with a low-calorie diet, this powerful hormone aids athletes in shedding excess fat while maintaining lean muscle. Women can also benefit from Pregnyl alongside a calorie-restricted diet to target unwanted fat.
The recommended dosage of Pregnyl typically ranges from 500 IU to 3000 IU per week, taken 1 to 3 times weekly. More frequent injections assist in maintaining stable blood levels, while a single high dose may raise estrogen levels due to testosterone aromatization, potentially causing gynecomastia. Some bodybuilders have reported using up to 6000 IU over six days, but it's essential to approach this with caution. For post-cycle therapy, a smaller dose of about 250-500 IU daily for 2 to 3 weeks is advisable to initiate the reversal of testicular atrophy. It is recommended to follow a 2 to 3-week hCG cycle, allowing at least a month off before starting anew, with treatment ideally commencing at the end of a steroid cycle.
While Pregnyl is effective, it?s crucial to be aware of potential side effects. Serious reactions may include severe pelvic pain, limb swelling, abdominal discomfort, shortness of breath, sudden weight gain, diarrhea, nausea, or vomiting. Common side effects may consist of headaches, irritability, mild water retention, depression, breast tenderness, and localized pain or swelling at the injection site. In boys, Pregnyl might trigger early puberty signs, such as voice changes, pubic hair growth, and increased acne or sweating.
