Even though your question is pushing the limits of our forum rules (publicly assuming we may sell unsafe products), here we go :-)
You can see a picture of the Retirides tube here:

We buy the tubes OTC from a pharmacy or multiple pharmacies in one of the very few European countries that allow that: Spain. Spanish pharmacies still only allow occasional small purchases for personal use, so we have a subcontractor in Spain that does nothing else but buying tubes and dropshipping them for us. So when you order this product, it is always shipped separately from your main order, and you'll find a Spanish postage stamp on the package. The tube comes with a list of ingredients enclosed by the manufacturer, but we also list them in our store.
European pharmaceuticals are subjected to at least the same strict tests, licensing and manufacturing regulations than in the US. The regulations are extremely strict, so strict that they seem to be designed to allow only the largest multinational pharmaceutical corporations to supply the European market.
