Potency and stability: why the assay report matters

In precision compounding, prescribing a concentration does not guarantee it reaches the patient intact. Between the formula and the vial there are variables — raw material, process, vehicle, time — that can move the product away from what was prescribed. The potency report is the instrument that closes that gap.

What the potency report proves

It attests to the real active concentration in the final product, against the prescribed value. It’s the difference between “should contain” and “contains”. In hormonal, precision-dermatology and injectable protocols, that proof is decisive.

Potency and stability go together

Stability determines for how long and under what conditions the potency holds. A product can leave the pharmacy correct and lose concentration if stored improperly. That’s why the prescriber should consider both: proven potency and the stated storage conditions.

Batch-to-batch reproducibility

Tracking clinical response is only possible if the formula is reproducible. With a per-batch potency report, the clinic compares what it received over time and keeps standardization — the basis for assessing the protocol.

How to ensure this in practice

PharmaLinker requires a per-batch report from partner pharmacies and gathers everything in the clinic’s sanitary dossier. Understand the technical terms in the compounding glossary and see the application by specialty in endocrinology and dermatology.
