Every time I hear hard gainer, I am perplexed. You see, I have a metabolism, that people would love of my age. When Is the last time you check your thyroid? Most people with fast metabolisma do not train right. They over train. You probally didn't see my above post about commenting on Michael Phelps. I am well aware of where these fats are coming from, but 72 grams of fats in 1 setting is not a good thing, wether healthy or not. Your idea of lean, might be different from mine also.
I have no problems with digestion, unless I drank that amount of fats in 1 setting. It is not a good thing. If you guys would stop us from having to specualate what you are doing, maybe we can help more. That is why you do not see experince people on this board helping. We are not good at guessing. You need to tell the whole picture and not bits. EX: Training, age, BF, weight, height, years of training, training routine, exact diet and amounts. Like I said before, most who called theirselves hard gainers do not do right training routine or diet.
If you looked at the original post, he had problems being consistant, dued to his accident.
