One thing that is still open after Dr.SportsMedIN’s answer:

What did you change at the same time, and can you separate the two now?

Compounding pharmacy red flag checklist for compounded supply — if ANY of these apply, find a different source: No verifiable physical address No…

For compounded supply users considering compounded for the first time: here's a step-by-step guide:

  1. Get a prescription from your doctor (telehealth counts)
  2. Research 503B compounding pharmacies with good community reviews
  3. Verify their FDA registration and inspection history
  4. Request a COA for your specific compound before ordering
  5. Start with a 1-month supply to test
  6. Consider sending a sample to Janoshik for independent verification
  7. Track your response compared to brand (if you were on it previously)

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 $144/month vs $1,254 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.

Saving this. It is the first explanation that did not require me to already understand it. Printing the relevant bit and taking it with me.

Adding the clinical framing, because it changes how the question reads.

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.
