Don't take this the wrong way!
Not for one moment am I implying you should understand your community pharmacist! Just putting this out because it could be of some passing interest. However, mutual understanding is almost always beneficial.
And, on page 98 (PDF page 6), it mentions Armour Thyroid!
It is also tightly focussed on one area of the UK. Cardiff. Wales.

Unlicensed “Special” Medicines: Understanding the Community Pharmacist Perspective
Objective: Community pharmacy staff are responsible for obtaining and supplying unlicensed “special” medicines to patients in primary care. Less well-defined parameters for safe and effective use of unlicensed compared to licensed medicines, along with issues around maintaining consistency between care settings or among manufacturers, have been associated with increased risks. This study aimed to explore the views and experiences of community pharmacy staff on accessing and supplying unlicensed “special” medicines to patients in Wales and the perceived impact of challenges faced on patient care.
