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

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 $133/month vs $1,383 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.

Adding a me-too, because a thread of one person's experience is not much use.

Price comparison for compounded supply across sources I've used:

SourceMonthly CostTypePurity Verified
Brand (Ozempic)$1055FDA-approvedN/A (pharma)
503B Compounding$135cGMP compoundedYes (in-house)
503A Compounding$125Patient-specificVaries
Research peptide$45Not for human useOften Janoshik

I use the 503B option — best balance of quality, cost, and legality. The brand price is insane but insurance can help if you qualify.

503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously:

Feature503A503B
RegulationState Board of PharmacyFDA-registered
PrescriptionRequired (patient-specific)Can compound without patient Rx
TestingVaries by statecGMP required
ScaleSmall batchesLarger production
Quality consistencyVariableGenerally higher

I strongly recommend 503B facilities. The FDA oversight and cGMP requirements mean more consistent product quality.

Regarding compounded supply compounding legality: compounding pharmacies can legally produce semaglutide and tirzepatide while these drugs remain on the FDA shortage list. If/when the shortage resolves, the legal landscape may change.

Stay informed. The FDA shortage list is updated regularly. Current status as of my last check: semaglutide partially resolved shortage, tirzepatide still in shortage. This directly impacts compounding availability.
