Thank s to everyone for your contribution.
So the main possible scenarios in my opinion are:
1) officially and concretely Balkan will produce only testosterone, and SP will produce also all remaining compounds. Each manufacturer with Its own branding on the final product. This would be the best and clearest scenario for us. We will know that everything that is not testosterone and is Balkan branded would be a fake.
2) Balkan continues to produce all compounds under its own brand but officially only testosterone. In that case, when the EU government asks for clarification on Balkan products on the underground market, what will Balkan declare? Necessarily that they are fake. At that point, even if the reseller has a good reputation, who would continue to buy products that the manufacturer himself declares to be fake? I definitely don't

there are yet many balkan fakes at present days
3) SP produces for Balkan and puts the Balkan brand on the products... but here too, at the request of the EU government, Balkan would be forced to declare that those on the market are fakes... and therefore we end up as in case 2. I would not buy Balkan again in this hypothetical scenario
In conclusion, it seems to me that the best option to avoid this unclear affair in the next future would be to buy exclusively SP (from an authorized reseller)
