Tesamorelin 20 mg vial

Prices from 12 vendors, and how much to draw for the commonly cited doses.

Read the regulatory status before you compare prices.

FDA-approved in 2010 for one narrow use: reducing excess abdominal fat in adults with HIV who have lipodystrophy. The label states in its own words that it is not indicated for weight loss management, because the effect on total body weight is neutral. It moves visceral fat and does not make you lighter. The label also notes that long-term cardiovascular safety has not been established, and it is contraindicated in active cancer and in disruption of the pituitary axis. Almost everything sold as tesamorelin for general fat loss sits outside that indication.

How to mix a 20 mg vial

Find the column for the amount of water you added to the vial. The number is how far to draw on a U-100 insulin syringe, where 100 units is 1 mL. This is arithmetic on the label, not a recommended dose.
