with 100 / day you can cut it day 2 if the metrics are trash, just read them and try to understand metrics, if cpc is low that means a lot of people will go on ur website so ctr is good even 2% based on all the clicks, if cpc is high 2-3$ you have to get a decent ctr like 3-5%, if cpm is high means ur ads are bad or u have a lot of competitors so search them and make different ads from competitors but focus on cpc and ctr, if 0 sales but high ATC rate means there is interest so let it 1 more day if all the metrics are trash cut it after 2 days, 200$ are enough to understand, just make sure to target 1-2-3 max audiences and not to many angles , start specific and then scale

@L S you should be profitable by day 4-5 with 100 / day, i usually test with ugc videos, or voiceover ads, if the situation is mid like in ur case with decent metrics and decent profit but not ready to scale at all you should focus on make new ads concept, split test is good but i think you will need a little bit more of trafic to split the people in 2 different pages so i will focus on ads and improving the offer to the best as you can

shopify payments and paypal, if u want u can add klarna but dont need

you can ask chatgpt to give you a full list of certification to ask to the supplier but you should have for sure your buisiness registered legally so that mean you collect european vat, and you pay taxes, for germany i think you have to register to some pharmaceutical autorithies to sell consumable products and health supplement aswel, you have to make sure the ingredients are all allowed in europe because some country can ban some type of ingredients, you have to make sure the product is lab tester and has CE certification before importing it, make sure you have a reliable supplier to communicate it and make sure you have a strong facebook setup because bans are near the corner for supplement, i've never run supplements especially in europe i would never do that, i would also avoid beauty products that are in direct contact with poeple skin like face cream or something like that for the ingredients test / registration and to avoid problem of allergies and stuff like that, you should privately message difaino and ask him a complete list or speak to a professional if you dont want to have risks, that's mean you have to have a lot of budget to get ready to sell supps, i would avoid it tbh

depend on what market u decide to test in, for europe 50/day can be good, for us u will need 100/ 150 $ day to test a product and the test goes from 3 days up to 5-6 depending on the budget, if you put all the effort in, you do your research etcc and maybe at test number 3 you are profitable you just have to start scaling after and ur free to go
