Two companies, one bank account

I recently purchased peptides from 2 ‘reputable’ peptide labs from China. Both are prominent and competing companies and both provide COAs on their website. Interestingly, they both have the same bank account details, including the name of the account holder.

I wonder how many other companies are owned by the person. My guess is that they buy their peptides from 2-3 large labs and are mostly resellers of the peptides under a different brand.
