I emailed Serena at
serena@xatzbiotech.com, she answered the same day and was very helpful and patient with my questions. I also got her Whatsapp number, but maybe start with contacting her via email first.
She said: "Alibaba prohibits uploading pharmaceuticals, so you can not access them".
You can buy in powder or capsules, I picked Ivermectin 12mg and Hydroxychloroquine 300mg capsules. 200 of each and the price was USD30 and USD50, shipping USD50, good price!
She send me a payment link and I paid with credit card, order content said "OEM Antioxidants Trans Resveratrol Capsule 500mg Anti-aging NMN Resveratrol Capsules"
We discussed customs a lot and she said "I have found a shipping agent who can handle customs, you don't have to worry about customs, transit time is 10-15 days".
