Fish Collagen and/or peptides: Which one and where to buy?

Hey guys. I wanna try out some fish collagen, but i don't know which product to purchase. Not sure where to start.

I was looking into Norland Hydrolyzed Fish Collagen (HFC): https://www.fintasticcollagen.com/

However, i stumbled onto this site: http://www.kenobio.com/eu/products/powder/collagen02.html

Apparently, hydrolyzed proteins are no good, as the molecular structure is destroyed. Unfortunately, they don't have a page on their site where you can buy kenobio fish peptides..

I'd like to find other fish collagen products, but can't find any sources that are "pure" (i.e. have no additives).

Can someone please recommend me a product here?

I'm posting in here a second a time to let people know that this is NOT a spam thread. I really need some recommendations here. thanks.
