Compounding pharmacy customer here with experience relevant to compounded supply.
I've ordered from 2 different compounding pharmacies over the past 2 years. 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 10 orders. I pay $157/month vs $1,267 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.

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.

I have been on both brand and compounded, and in the context of compounded supply, my experience has been equivalent with both. The key is finding a reliable 503B pharmacy with independent testing.
