Yeah im in a small town and they do froth on all that certified shitRegistered dietitian, certified nutritionist are not selling points for me.
What i would look for:
Quality ingredients
Macro breakdown
Calories.
I want this info easily available, like a big ass sticker
50g Protein , 10g fat, 10g carbs etc.
After that it's just hook lines.
WH's Mass gainer
WH's Post WO treat
WH's Low Cal hunger buster

I already have a rock solid name locally for my meals and I sell out every time but it's purely just another sector that won't cost me anymore outlay besides the course itself so I thought, why not.
I'm always looking to potentially expand. I'm also doing a PT course but I know i won't in fact use it, I'm just a guy that likes to fully immerse myself and learn. I'm better off doing that then sitting on my arse watching TV.
The PT side of the business id probably sub contract out if i ever introduced into my business model.
