Protein & Weight Gain is the starting point for protein shakes and calorie-dense gainers. Browse whey concentrate, whey isolate, casein, plant protein, mass gainers and protein bars from Trec Nutrition, LEVRONE, BAD ASS, 10X Athletic, Premium Nutrition and DY Nutrition, then narrow down by type below.
Which type of protein suits you?
Each format does a slightly different job. Start with the one that matches how you eat and train:
- Whey Protein: whey concentrate, the everyday shake and the best value per serving. Labels typically give 22–25 g protein per scoop.
- Whey Isolate: filtered further for more protein and less sugar, fat and lactose per scoop, at a higher price.
- Casein Protein: the slow-digesting milk protein, usually taken in the evening.
- Vegan Protein: plant-based powder for dairy-free and vegan diets.
- Mass Gainers: protein plus a large carbohydrate dose for people who struggle to eat enough calories.
- Protein Bars & Snacks: bars and wafers for when a shaker is not practical.
What protein does, and how much to use
Protein contributes to a growth in muscle mass and to the maintenance of muscle mass, and it contributes to the maintenance of normal bones. Those claims rest on your total daily intake, so a shake simply makes a target easier to hit when meals fall short; the time of day matters far less. Follow the serving on the label, and remember that a food supplement is not a substitute for a varied, balanced diet.
Beyond standard whey
Not every protein here is a milkshake. 10X Athletic Clear Beef Isolate mixes into a light, juice-style drink with 28 g protein per serving, is dairy- and lactose-free and is Informed-Sport certified. Trec Nutrition Protein 100 is an easy-drinking all-rounder in 700 g and 2000 g jars. If you also use creatine, the DY Nutrition stacks pair Shadowhey with The Creatine, and more combinations sit in Protein & Mass Gain Bundles. Every format mixes best in a proper shaker with a mesh insert.
Protein & Weight Gain: your questions answered
Whey, isolate or casein: which should I buy first?
Start with a whey concentrate unless you have a reason not to, because it gives the most protein for your money. Move to isolate if you want fewer carbs and less lactose per scoop, and add casein if you want a slower-digesting evening shake.
Do I need a mass gainer or a protein powder?
It depends on calories. If you already eat enough and just want more protein, choose a whey or vegan powder; if your weight will not move however much you eat, a gainer adds carbohydrate calories on top of the protein.
Can I use protein powder if I don't go to the gym?
Yes. Protein powder is a food, and a shake is a convenient way to top up protein for anyone whose meals fall short. It should add to your meals, not replace them.
Do you have dairy-free protein?
10X Athletic Vegan Protein is plant-based and suitable for vegans. 10X Athletic Clear Beef Isolate is also dairy- and lactose-free, but it is made from beef, so it is not vegan or vegetarian.
