Am looking for nf capsule from your products in tanzania

I did a google for you, finding out herbal versions seem very popular in India, but finding nothing in your country.
That suggests your best bet could be to find the Indian communities, especially Indian managed pharmacies nearest to you.
The tablets have no potential for abuse so are probably legal everywhere.
Sort supply might mean if you find a place that sells them you'll have to come early if you want to guarantee getting some.
