Spotting Counterfeits ​

Why Counterfeits Are Dangerous ​

Counterfeit HRT medications pose serious risks:

  • Under-dosed — no hormone effect (wasted money, delayed transition)
  • Over-dosed — dangerous side effects (toxicity, blood clots, liver strain)
  • Wrong substance — different medication than labelled (e.g., sugar pills, or worse — other active drugs)
  • Contaminated — bacteria, heavy metals, toxins, fungal contamination
  • Non-sterile injectables — risk of abscess, sepsis, or blood infection

Injectable Medications (Vials) ​

Visual Inspection Checklist ​

CheckWhat Genuine Looks Like❌ Counterfeit Indicators
Solution clarityClear, no visible particles — colour varies by oil (MCT = clear, grapeseed = pale yellow, sesame = golden)Cloudy, hazy, floating specks, fibres, crystals
Vial sealCrimp cap is smooth, even, and intactLoose, dented, or re-sealed cap; signs of tampering
Rubber septumClean, no visible wear before first useMultiple puncture marks, discoloured, debris
Label qualityProfessional printing, clear text, no smudgingBlurry text, misspellings, poor alignment, generic plain label
Batch/lot numberClearly printed, alphanumeric, 6+ charactersMissing, handwritten, or appears on a sticker (not printed)
Expiry datePresent, legible, reasonable timeframe (2–3 years from mfg)Missing, smudged, or > 3 years from manufacture date
ConcentrationClearly stated (e.g., "250 mg/mL")Missing or ambiguous concentration
Carrier oilOil type listedNo oil specified
ManufacturerVerifiable pharmaceutical company or known homebrewerUnknown or fake manufacturer name

The "Float Test" for Oil-Based Injectables ​

Drop a tiny amount of the oil into room-temperature water:

  • Genuine: Oil should bead up and float (lower density than water)
  • Suspicious: If it immediately disperses or sinks, it may not be oil-based

⚠️ This is NOT a definitive test — use blood tests or HPLC for verification.


Pills / Tablets ​

Visual Inspection Checklist ​

CheckWhat Genuine Looks Like❌ Counterfeit Indicators
Shape and sizeConsistent across all pillsVaried sizes, irregular shapes, chipped edges
ColourUniform shade throughoutUneven colour, speckled, spots
Imprint codeClearly stamped, matches known referenceMissing, blurry, incorrect code, or easy to scrape off
Score lineClean break line (if applicable)Off-centre, barely visible
Blister packProfessional foil, consistent pocket sizesCheap-looking foil, inconsistent pockets, easy to tear
Packaging textClear, no errorsMisspellings, grammatical errors, poor print quality
Batch/lot numberOn both blister pack AND outer boxMissing from either; mismatched numbers

Common Imprint Codes for HRT Medications ​

MedicationCommon ImprintTypical Appearance

Gel Packets / Sachets ​

CheckWhat Genuine Looks Like❌ Counterfeit Indicators

At-Home Testing Methods ​

Water Test (Pills) — ⚠️ NOT Reliable ​

Some people recommend dropping pills in water or vinegar to observe behaviour (e.g., sinking vs. floating, colour change). These tests are not scientifically validated and should NOT be used to determine authenticity.

Blood Test Verification — ✅ Most Reliable ​

The single most reliable way to verify your medication is to check your blood levels at a known dose:

MedicationExpected Level at Standard Dose
Estradiol 4 mg/day (oral)E2: 60–100 pg/mL (trough)
Estradiol 6 mg/day (oral)E2: 100–200 pg/mL (trough)
Testosterone 100 mg/week (injectable)Total T: 700–1,000 ng/dL (trough)
Spironolactone 100 mg/dayT levels should be suppressed (varies)
CPA 12.5 mg/dayT levels should be significantly suppressed

If your levels are far below what the dose should produce, the medication may be under-dosed or counterfeit.


Third-Party Laboratory Testing (Gold Standard) ​

For absolute certainty, send a sample to a testing lab:

TestWhat It MeasuresTypical Cost
HPLCExact concentration of active ingredient$100–$200
GC-MSFull compound identification + quantification$150–$300
Sterility testingBacterial/endotoxin contamination$50–$150
FTIRQuick identity check (is this the right substance?)$50–$100

Community testing pools: Some Reddit communities organise group buys — multiple people contribute to test one batch, splitting the cost.


Batch Numbers and Authentication ​

What Legitimate Products Have ​

  • Clear batch/lot number printed on the label
  • Format: Alphanumeric, typically 6–12 characters (e.g., "B2401A", "LOT2401001")
  • Machine-printed (not handwritten or stickered)
  • Cross-reference: Some manufacturers have online verification portals

Red Flags ​

Red FlagWhy
Batch number is handwrittenUnprofessional, untraceable
Batch number on a sticker (not printed)Easy to fake and replace
No batch number at allNo traceability
Multiple products share same batch numberEach product run should have a unique batch
Expiry > 3 years from manufactureUnrealistic for most medications

Red Flags Summary ​

❌ Red FlagWhy It's a Problem
Price far below market averageLikely under-dosed or counterfeit
No photos of actual product (only stock images)Seller may not have the product
Refuses to share batch info or testingHiding something
Packaging looks generic, no brandingNot from a legitimate manufacturer
Seller has many negative reviews in last 3 monthsTrust community consensus
Pressures you to buy quicklyPrevents research; classic scam
Only accepts Western Union / MoneyGramNo buyer protection or recourse
Website looks unprofessional / full of errorsLikely a scam operation
Product looks different from community reference photosCompare before using
Label has spelling mistakes (e.g., "Estradoil", "Testosteron")Unprofessional; counterfeit indicator

What to Do If You Receive Suspect Medication ​

  1. Do not use it — contaminated or incorrectly dosed medication can cause serious harm
  2. Take clear photos — of the product, label, packaging, and batch number
  3. Post to community forums — r/TransDIY, r/FTMDIY, or relevant Discord for verification
  4. Contact the seller — some legitimate sellers will replace or refund
  5. Warn the community — post a review to help others avoid the same issue
  6. If you already used it and feel unwell — seek medical attention immediately
  7. Dispose safely — do not flush; take to a pharmacy drug take-back program
