Recommended product: PRO 100% Whey Whey Protein Powder
 
Founded in the United States in 1935, GNC has been ranked as the No. 1 franchise brand of vitamins and nutritional foods in the United States for four consecutive years, and is also a reference to industry standards, and its quality control system has been selected by the U.S. FDA as a template for dietary supplement products. Although it is still a health supplement giant, GNC's sales have stagnated for several years, and since 2015, GNC's revenue has declined significantly for three consecutive years. In addition, in 2015, GNC was prosecuted for the addition of the banned ingredients picamilon and amphetamines.
 
At present, there are very few GNC animal protein powder products available for purchase through formal channels in China, only PRO 100% Whey Whey Protein Powder, Pure Isolate Whey Protein Isolate and PRO Weight Gainer Weight Gainer Powder. These products have good data in terms of protein content, ingredients, calories, etc., without too many additives, and are not outstanding, and the taste design is classic and conservative with few choices. In addition to PRO 100% Whey Whey Protein Powder, the other two are much more expensive than similar products.
 
PRO 100% Whey Whey Protein Powder is mainly composed of whey protein concentrate and whey protein isolate, with a protein content of about 68%, and 5 pounds of PRO 100% Whey is about 500 yuan, which is moderately priced. Pure Isolate Whey Protein Isolate has a protein content of 78%, about 480 yuan for 2 pounds, and its price is almost twice that of Dymatize and Isopure Whey Protein Isolate if calculated by protein content, so it is not particularly recommended to buy.
 
PRO Weight Gainer is a protein complex blended with soy protein powder in addition to the common concentrates, whey protein isolates, and casein. The nutritional value and absorption rate of soy protein is slightly lower than that of whey protein and casein, and generally speaking, mixed plant protein can reduce costs, but this weight gain powder is currently on the high side, 240 yuan can only buy 2.5 pounds, based on the number of servings and protein content, the price is 1.5 times higher than BSN True-Mass and MuscleTech MASS-TECH weight gainers, not recommended.
