Body Type: A Key Factor in Choosing the Right Supplement
Mass gainers and weight gainers should be taken according to your body type. Here are the three main body types:
Endomorph — Heavier, rounded individuals with a wide frame and more fat stores. Endomorphs have a slower metabolism and easily put on muscle mass.
Mesomorph — In between endomorphs and ectomorphs. Mesomorphs have lower body fat, toned and muscular arms and legs, and a fast metabolism. They can gain muscle mass easily.
Ectomorph — Lean individuals with a long, slender physique, low body fat, low muscle mass, and a fast metabolism. Ectomorphs have difficulty building muscle and gaining weight.
Mass Gainer

A mass gainer is a high-calorie supplement tailored to help individuals meet the calorie requirements for gaining muscle mass. Mass gainers typically include carbs and protein in a ratio of 5:1 or 3:1, together with multivitamins, multiminerals, and enzymes. The high calories keep the body in a positive energy balance, while the protein content supports putting on muscle mass. Mass gainers are a good source of calories and protein for those trying to build muscle during periods of intense training.

When to Take Mass Gainer?
The whole intention of supplementing with a mass gainer is to boost caloric intake conveniently, so timing isn’t the primary concern. Consuming it first thing in the morning shifts your body into an anabolic phase. Taking it post-workout helps replenish muscle glycogen stores and supports faster recovery. Before bed, it keeps the body in an anabolic state — which is important for adding body mass.
