Pills That Make You Gain Weight Fast

Whether you want to gain weight to fill out your jeans or to make a certain cut for a sports team, you may have considered taking a weight gain supplement. Weight gain pills can help you pack on pounds quickly, but there may be health risks involved. Before taking a weight gain pill, talk to your doctor.

Methyltestosterone increases testosterone production, according to Drugs.com. Although this drug isn't prescribed for weight gain, many athletes use methyltestosterone for this purpose, according to MayoClinic.com. It can be taken with or without food, but should an upset stomach occur, food is recommended to offset this side effect. It's very important to follow the directions provided by your doctor or pharmacist. Weight gain is listed as a severe side effect, according to Drugs.com, along with a severe allergic reaction, lumps on your body, pain and unusual bruising or bleeding. Methyltestosterone may interact with other drugs such as diabetes medications.

Oxandrolone, an anabolic steroid, is typically prescribed for those who need to gain weight after a severe weight loss due to surgery, injury or medical conditions such as osteoporosis, according to MedlinePlus. Generally, oxandrolone is used in conjunction with a healthy diet and exercise program to increase weight gain. It works by increasing the amount of protein that your body produces, which helps you gain more muscle mass, and thereby more weight. Doctors who prescribe oxandrolone typically order patients to take the medication for two to four weeks, depending upon the amount of weight you need to gain. Your doctor may write a new prescription after a short period of time if you begin to lose weight instead of maintaining the weight you've already gained.

The Department of Dermatology at the University of Essen, in Germany, conducted a study to test the effectiveness of oxymetholone for weight gain in patients with HIV. Three groups of individuals were tested. The first group took only oxymetholone while the second group took oxymetholone along with the steroid ketotifen. The final test group took no therapy medications at all. The outcome of the study concluded that oxymetholone was more effective when used alone to aid in weight gain than with the use of other medications that support weight gain. The test subjects who used only oxymetholone gained just over 14 percent of their original starting weight over the course of eight weeks.
