What's the most effective way to test products for organic dropshipping?

I'm new to organic dropshipping, and I'd like to ask the most effective way to test products:

Option 1: Create several Instagram accounts and test one product on each account. If one of them goes viral, then start building the store and look for a supplier.

Option 2: Research one promising product first, find a supplier, then focus on testing that product on a single Instagram account for about 2–3 weeks. If it performs well, build the store. If not, move on to another product.

The issue is that I want to sell potential products, because i think if a product goes viral, new accounts pop up everywhere and it becomes much harder to compete.

I usually look for suppliers on AliExpress, but not every product has a supplier with enough inventory. Sometimes the product isn't even available on AliExpress.

So here's my concern:

• If I choose Option 1, by the time a product goes viral and I start looking for a supplier, I might not be able to find one selling that product. Or I might find one, but they don't have enough inventory, or there are other issues like slow shipping, etc.
• If I choose Option 2, I can focus only on testing the product, but it takes much longer, and it's easy to get discouraged if the product doesn't work.

Does anyone have a good product testing method or workflow that you'd be willing to share? I'd really appreciate hearing any methods or workflows that have worked well for you. Thanks!
