How large are the pills?

They are 1000 mcg. Not very large or thick. Easy to swallow. About the size of my round iron pills or a regular aspirin. Hope that helps.

Does this product come with a 100% money back guarantee?

I don't think so, but you might want to read what the manufacturer has to say about that.

this says it has gelatin so how is it vegetarian/vegan friendly?

The Biotin 1,000mcg Tablets (Prod No. 7961) do not contain gelatin and are suitable for vegetarians and vegans.

Could a teen at the age of 14 take these?

This is a dietary supplement and I would get advice from a medical doctor about giving supplements to a 14 year old child. The label only gives instructions for use by an adult.
