In an unregulated market, a vial labelled one thing can contain something else, less of it, or bacteria. No home check can prove a product is genuine, but several warning signs make problems far more likely. This guide covers what to look at before using anything and what to do if something seems off.
- Check packaging, seals, batch numbers and expiry dates before anything else.
- Oils should be clear at room temperature; particles, persistent cloudiness or separation are red flags.
- Prices far below the market for expensive compounds often mean underdosing or substitution.
- Bloodwork and, where available, independent lab testing are the only real confirmation.
Packaging and labels
- Seals: flip-off caps and crimp seals should be intact and uniform.
- Printing: crisp, correctly spelled text; matching fonts and colours across a brand’s range.
- Batch and expiry: both should be present and should match the box and the vial.
- Consistency: compare with a product you know is genuine from the same brand if possible.
Our guide to reading a steroid label explains what each line should tell you.
Looking at the oil
Injectable oils should be clear and free of particles at room temperature. Colour varies with the oil and compound, so it is not a reliable test on its own. Cold can cause crystals or cloudiness that disappear when the vial is warmed gently; if they remain at room temperature, do not use it. Visible floating particles, a layer separating out, mould or an unusual smell are reasons to stop.
Tablets
Tablets should be uniform in size, colour and markings, with clean edges, and should not crumble. Sealed bottles or blister packs with batch details are better than loose tablets in bags.
Price and availability
Some compounds, such as methenolone (Primobolan) and oxandrolone (Anavar), are expensive to make. When they are offered at a fraction of the usual price, underdosing or substitution with a cheaper compound is common. Constant “deals” on everything, or a seller who always has every compound in stock, can be warning signs too.
Seller behaviour
- No way to contact them, or questions that go unanswered.
- Pressure to buy quickly or pay in unusual ways.
- No clear policy for lost parcels or wrong items.
- Claims that a product is “pharma grade” without any detail.
A hot, swollen, increasingly painful injection site, fever after injecting, or effects that do not match the compound at all are reasons to stop and see a doctor, and to keep the vial for reference.
Using bloodwork as a check
If you use testosterone, a blood test a few weeks in should show levels consistent with the product. Testosterone that does not rise suggests an underdosed or fake product; very high levels suggest the opposite. For other compounds, suppression of LH and natural testosterone shows something androgenic is present, though not which compound.
Independent testing
Some laboratories and community testing programmes analyse steroid samples for identity and amount. A result applies to the specific sample, but it can reveal a bad batch.
What to do if unsure
Do not use it. Contact the seller with the batch number and photos. A reputable seller will investigate and replace a faulty product.

Frequently asked questions
Can I test steroids at home?
Home reagent kits can suggest the presence of some compounds but cannot confirm amount or purity.
Is cloudy oil always bad?
Cold can cause temporary cloudiness that clears when warmed. If it stays cloudy at room temperature, do not use it.
Are cheap steroids always fake?
Not always, but very low prices for costly compounds are a common warning sign.
