Whats the best way to get peptides in Colombia?

For Colombia, I would not want to treat peptides like a simple online shopping question. The word can cover a lot of different things, from approved medicines to research compounds that are not meant for human use, and those are very different situations. The best way, at least from the outside, seems like starting with the medical and regulatory route instead of asking the internet for a shortcut. So whats the safest way to get peptides here?
