FDA inspection results for compounding pharmacies selling compounded supply: you can look up any 503B facility's FDA inspection history on the FDA website.
Check for: Form 483 observations (violations), warning letters, and recall history. A clean inspection record is a strong indicator of quality. My pharmacy has had 1 Form 483 observations in their last 2 inspections.

Compounded has been just as effective for me. If compounded supply is the concern, the COA from my 503B pharmacy shows 99.1% purity. Verified by Janoshik.

Compounding pharmacy customer here with experience relevant to compounded supply.
I've ordered from 5 different compounding pharmacies over the past 18 months. The quality variation is real — purity ranged from 94% to 101% of label claim based on independent Janoshik testing.
My current compounder (a 503B facility) has been consistently 98-101% purity across 5 orders. I pay $152/month vs $1,222 for brand. The savings are substantial and the product is equivalent in my experience.
Re: compounded supply — this applies whether you're using brand or compounded. The clinical principles are the same.
