Anybody remember Infinity 1700? Would mix up a whole serving in a blender and drink it all in a few minuts. Then shortly after get a stomach ach and head straite to the bathroom everytime. I think it only happed a few times because I then cut the serving in half, but it still upset my stomach to a certain degree. Never got another one after that.
Pre-soaking the oats can make a HUGE difference for myself and many who I have helped. Just cover in water in the fridge the night before or even a couple hours before consuming can make a world of difference.
I usually reccomend this one when people are not interested in making their own(ZERO young guys are interested in making their own and actually look at me like I speaking a foreign language when I lay out the concept to them.)
Rule1 Gain has a reasonable carb/pro ratio and when you add whole milk and a couple tbsp PB you can split it into two servings per day.
I also have many repeat customers for this formula: Hi-Tech Critical Mass (best carb blend I have seen in a pre-made gainer)
When you buy carb powder and protein separately you actually don't save a whole lot of money when you do all the math, there is a little savings but not enough for an 18 year old to arsed with it. I try to steer guys away from products like this:
The carb/pro ratio is trash and when you cut the 334g "serving" size in half you get too low of protein. IMO the greatest advantage of homemade is NOT cost savings but ability to dial in the macros exactly as you see fit. Young guys are still lured in by the high numbers on the front and when I try to explain the 1000 calorie gainer is simply double to serving size of the 500 they give me the deer in headlights look. Oh, well I try.
Soaking grains, nuts, seeds, lentils, beans seems to improve digestion of them. Has something to do with deactivating lectins or phytic acid or some other thing, I don't remember. But it is a very common practice and sure makes beans easier to digest as well. It cost nothing to do, is easy, and works so I never did a deep dive on the "why."
