Supplement quality
Much like in the real world, the benefits of taking any supplement are hard to measure. Clever marketing and slick product design may convince you that the product you are taking is of high quality but in reality it might be a tub of ground up chalk and candy hearts.
In MMA Tycoon, the situation is no different. The nutrition producer can choose to set the quality at whatever level he wishes but that level is never disclosed to the public. The only way you can find out is by talking with other users and assessing what benefits you are getting from training with each make of supplement. Is the manufacturer out to make a quick buck or are they a reputable source for all your nutritional needs? Discuss the matter in the forum to pass on tips to your fellow users!
