What about mass gainer post-workout supplements?
A weight gainer or mass gainer is a supplement that combines protein and carbs (usually maltodextrin) to help you consume more calories. So why not use a weight gainer instead of buying powders separately?
In my 20s, I tried using a mass gainer supplement to help me gain weight. I mixed four scoops with milk in a pitcher and drank it throughout the day, including after my workouts. While I did manage to gain weight, I also gained a lot of fat as a result.
The reason for this is that weight gainers typically contain a lot more carbohydrates than protein. In fact, some weight gainers have a ratio of 250 grams of carbs to just 50 grams of protein, which is a 5:1 ratio. For a post-workout shake, a better ratio would be 2:1.
Another issue with weight gainers is the price. On average, they can cost around $3 per serving. It’s much more cost-effective to purchase protein and maltodextrin or dextrose separately, as this gives you more control over your macronutrient intake.
Overall, unless you’re an extremely hardgainer looking for the easiest way to add extra calories to your diet, I wouldn’t recommend using a weight gainer supplement.
