Xtreme Gainer - how long will it take to gain weight and are there side effects?

A female taking a mass gainer lol , never heard that one before . It has a ton of calories and consuming alot more calories then usual will always end in weight gain. Your body has to do something with them. This isn't normally the way a female would gain weight but make no mistake it will work . Also before you even wonder no taking protein or a mass gainer won't make you magically get buff or gain muscle . What you should do is take one day out of the week to prepare meals and have them left in the refrigerator beforehand so you have your weeks worth of food done . I know cooking is annoying and this is a remedy for that
