Someone advised me to use GC-Maf as a supporting therapy. What does it encompass?

GC-Maf is marketed as a powerful stimulator of the immune system. We have presented results of clinical trials to experts and they have concluded that external, more thorough studies are needed to confirm these initial results.

The website offering GC-Maf online does not mention anything about the quality of the product. Furthermore, despite repetitive tries, we have failed to get in touch with them for more precise information about their product. It is unclear whether they have the right to sell this drug.
