Verifying Product Quality
Why Verification Matters
Counterfeit, under-dosed, or contaminated HRT medications are a real risk — particularly when buying from unregulated sources. Using poor-quality medication can lead to:
- No hormone level changes (wasted money, no results)
- Unsafe ingredients (contamination, allergic reactions)
- Unexpected side effects
- Delayed transition progress
Visual Inspection
Pills
| Check | What Genuine Looks Like |
|---|---|
| Shape and size | Consistent; no chips or cracks |
| Colour | Uniform; matches known reference |
| Markings | Clear imprint codes (e.g., "E 2") |
| Packaging | Blister packs with batch number and expiry date |
| Expiry date | Present and legible |
Injectables (Vials)
| Check | What to Look For |
|---|---|
| Solution clarity | Clear, colourless or slightly yellow — no cloudiness |
| No particles | No floating specks, fibres, or crystals |
| Seal | Crimp cap is intact; no signs of tampering |
| Labelling | Clear label with concentration, ester, batch number, date |
| Storage | Stored at room temperature, away from light |
At-Home Testing
Water Test (Pills)
Some estradiol pills will sink or behave differently in water than counterfeits — but this is not reliable and should not be your primary verification method.
Blood Test Verification
The most reliable way to verify your medication is to check your blood levels:
- Start at a known dose
- Test E2 (trough) after 4–6 weeks
- If E2 levels are far below what the dose should produce, the medication may be under-dosed or counterfeit
For example: 4 mg/day of genuine oral estradiol should produce E2 levels of roughly 60–100 pg/mL (trough). If you get < 30 pg/mL, something is wrong.
Third-Party Testing
Some community organisations or suppliers offer:
- HPLC testing — quantitative analysis of estradiol content
- Sterility testing — checking for bacterial/endotoxin contamination
These are the gold standard for verification but require sending samples to a lab.
Batch Numbers and Authentication
- Legitimate pharmaceutical products have batch/lot numbers
- Some manufacturers have online verification portals
- If the batch number is illegible or missing, this is a red flag
