KLR.FIT E3 1RX is a potent weight gain formula designed for hard gainers, who struggle to put on weight, suffer from extremely fast metabolism and have a poor appetite. While the fitness market is cram-full of weight-loss products, hard gainers have very limited options to choose from.

That’s where KLR.FIT E3 1RX comes in.

A unique blend of Natural Herbs, Vitamins, Minerals, Phytosterols and DHEA, E3 1RX will help you achieve your weight gain goals in no time. Each serving of E3 1RX is powered by 1600 mg of Natural Phytosterols which not only help you put on healthy weight but also help reduce cholesterol levels. 30 mg of DHEA, a powerful precursor to testosterone, which boosts appetite, increases strength and helps you put on muscle mass while keep unwanted fat gain at bay. And last but not the least, a powerful combination of Echinacea herbs, Zinc and Vitamins C, D and E, that improve immunity, reduce fatigue, increase energy, improve appetite and ultimately lead to healthy weight gain in underweight individuals.

Unlike generic weight gain pills which only make you gain temporary water weight, E3 1RX contains safe, evidence-backed ingredients that help you gain quality body weight and maintain it. Simply take 2 capsules 45 minutes before breakfast and lunch, and watch your body transform.




As a dietary supplement, take 2 capsules 45 minutes before breakfast and 2 capsules before lunch.
