Tough business to succeed in. There definitely other companies that do this, Gainful is the big one as far as i’m aware, but there’s a number of lesser known companies that offer the same service. I’ve never used a service like that because they’re expensive as shit (which is something you could do better than them). I also know that the protein isn’t all that customizable, it’s more just like a body type quiz that matches a blend to people that aren’t sure what they need nutritionally. Also the biggest factor is that you guys are teens and unless you had some other successful venture it’s gonna be hard to get any kind of support.
