Lean Gainer MRP from Protein Factory is a protein supplement for bodybuilders who want to pack on weight during the growth phase. Gainers typically have lots of calories so they are not appropriate for use by dieters wishing to lose weight. This supplement contains whey protein along with other healthy ingredients. The Lean Gainer MRP supplement is a meal replacement protein. This means the supplement includes vitamins and minerals, mimicking an entire meal.

Protein Factory does not offer free trials of protein powder. This is a problem, because the taste for Lean Gainer MRP is listed as a 6 out of 10 stars. There are many choices in protein, some of which tastes great, so the product should have strong testimonials to back the effectiveness. Unfortunately, Protein Factory does not list testimonials. The product price starts at $10.33. Consumers can personalize the meal replacement shake by adding ingredients like creatine, peak ATP, muscle cocktail and Microlactin, for an added price.

List of Ingredients

CFM Whey Isolate, Soy Isolate, Hydrolyzed Whey Protein, Flax Powder, Fish Oil Powder, Vitamins and Minerals.

Product Features

The best aspect of Lean Gainer MRP is the fact that consumers can create a personal meal replacement with added ingredients and unique flavors. Available flavors include banana, chocolate, Cinnabun, fruit punch, raspberry lemonade and gourmet vanilla. However, only 60% of the people who drink the shake, like the taste, according to the 6 out of 10 ranking provided in the product description.

As a gainer, we expected a ton of calories, but Lean Gainer MRP contains only 370 calories per serving. One serving requires the consumer to add one cup of the powder to water or other liquid. One scoop of the average protein powder is difficult to mix, let alone one cup. The taste has to be gritty, but no testimonials are listed so we have no idea what consumers feel about the product.

Flax is a great source of fiber, but Protein Factory lists this ingredient as a possible fat burner. Flax does not boost metabolism or heart rate. In order to burn fat, these events have to occur in the body. Flax will, however, support a healthy colon.

There are 81 grams of protein per serving. Increasing protein is one thing, but taking too much in one sitting is another. If the body receives too much protein, it will convert that protein into carbohydrates.

  • Cheaper than the average meal replacement shake.
  • Consumers can order the product online.


  • May contain too much protein.
  • No testimonials.


Lean Gainer MRP contains only 370 calories per serving. The fact that it takes one cup for each serving is far too much for the average dieter or bodybuilder. There is no way this powder dissolves completely in liquid and thus it is probably not very palatable.
