Resistance Potion/Elixir of Fortitude

Does anyone know if this potion is dropped in GMS. It's listed as a drop from HT under the name resistance potion but i have yet to see any in the fm; unfortunately the coin shop does not carry it either.

Elixir of Fortitude (Status Resistance +30%) x1
- Superior Empty Bottle x1
- Juniper Berry Seed Oil x10
- Superior Item Crystal x3
- Philospher's Stone x1

Sorry for not posting in the Profession thread, it said i wasn't allowed.

Thanks.
