UK company with UK/EU bank account for grey market products (peptides / sarms)

Dear Offshore Corp Members,
I have I question.

I am turkish citizen and I want to make my grey market business legal with company...
I sell since years anonymous Peptides and Sarms as research chemicals inside the EU and have a solid customer base.
This products are for bodybuilding and beauty. I sell for 30-50K Euro per month this products.
A friend in Austria send this products for me and I get the money yet by bank transfer to turkey.

Now I want to make my business legal and open in UK (where this products are allowed as research chemicals) a Ltd.
I have a company there which will rent me the office and make for me the ltd registration.
But I know that it is difficult to get a business bank account for this uk company because UK didn´t give a VAT number out (only from 50K+ after 1 year...).

Had anybody an idea how I can create this constuct and get my business bank account without the VAT number?
I will be happy for every helpful answer.
