Following on from james_edin — and this may be the naive question:

What would you measure differently if you were starting again?

Vendor communication red flags for compounded supply: Won't provide COA before purchase — walk away Claims "100% pure" without analytical data —…

Compounding pharmacy red flag checklist for compounded supply — if ANY of these apply, find a different source:

1. No verifiable physical address
2. No pharmacist available for consultation
3. COA not available or clearly template/fake
4. Prices dramatically below market ($30-40/month = suspicious)
5. No prescription required
6. Ships without cold pack or temperature control
7. No batch/lot numbers on product labeling
8. Pushes "research use only" products for human injection

Your health depends on product quality. Don't cut corners on source verification.

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 $125/month vs $1,395 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.

Genuinely useful, thank you. I had the facts and not the framework.

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.
