The number printed on a CBD oil label — 1000mg, 3000mg, 6000mg, 12000mg — tells you how many milligrams of cannabidiol are in the entire bottle, not in each drop. Knowing how to convert that figure into a per-mL concentration is the most useful thing you can do before choosing a bottle. This guide covers the maths, the label language, and where to find multiple strengths available for delivery across Perth and Western Australia.
What does mg mean on a CBD oil bottle?
The mg figure on a CBD oil label is the total cannabinoid content of the whole bottle. If the label reads 1000mg and the bottle holds 50ml, every millilitre of oil contains 20mg of CBD. That single calculation — divide total mg by total volume — is the key to comparing any two bottles, regardless of brand, size or price.
It does not tell you how much to take. It does not refer to a single serving. It is a declaration of what is in the bottle, the same way a food label declares kilojoules per 100g.
A bottle of full-spectrum CBD oil and a bottle of broad-spectrum CBD oil can both carry a 1000mg label. The mg figure describes the cannabinoid amount; the spectrum descriptor tells you whether trace THC is present. These are two separate pieces of information and both matter when you are comparing products.
How to calculate per-mL strength
The arithmetic is straightforward. All four strengths in the CBD Oil Perth range come in a 50ml bottle, so the per-mL figures are fixed:
| Label strength | Bottle volume | CBD per mL | Per 0.5ml dropper |
|---|---|---|---|
| 1000mg | 50ml | 20mg/mL | 10mg |
| 3000mg | 50ml | 60mg/mL | 30mg |
| 6000mg | 50ml | 120mg/mL | 60mg |
| 12000mg | 50ml | 240mg/mL | 120mg |
A standard dropper holds roughly 0.5ml of oil. Multiply 0.5 by the mg/mL figure to get the amount per dropper. So a 3000mg bottle delivers 30mg per half-dropper serving; a 6000mg bottle delivers 60mg in the same physical quantity of oil.
These numbers matter when you are comparing bottles of different sizes. A 30ml bottle labelled 1000mg contains 33mg/mL — a meaningfully different concentration to the same label on a 50ml bottle at 20mg/mL. Always divide total mg by total ml; never compare labels by the headline number alone.
Our CBD oil strengths: 1000mg to 12000mg
CBD Oil Perth stocks four strengths across two spectrum types, plus CBG and CBN oils at matching strengths. All are in 50ml MCT bottles, lab-tested by batch, with a Certificate of Analysis available on request.
Full-spectrum range (trace THC under 0.3%)
- CBD Oil 1000mg — Full Spectrum from $89.95 — 20mg/mL, a 0.5ml serve delivers 10mg.
- CBD Oil 3000mg — Full Spectrum from $220.00 — 60mg/mL, 30mg per 0.5ml serve.
- CBD Oil 6000mg — Full Spectrum from $390.00 — 120mg/mL, 60mg per 0.5ml serve.
- CBD Oil 12000mg — Full Spectrum from $585.00 — 240mg/mL, 120mg per 0.5ml serve.
Broad-spectrum range (0% THC)
- CBD Oil 1000mg — Broad Spectrum from $89.95
- CBD Oil 3000mg — Broad Spectrum from $220.00
- CBD Oil 6000mg — Broad Spectrum from $390.00
- CBD Oil 12000mg — Broad Spectrum from $585.00
The difference between full-spectrum and broad-spectrum is one fact: full-spectrum retains a legal trace of THC (under 0.3%); broad-spectrum has THC removed entirely. Everything else — the CBD content, the MCT carrier, the 50ml volume, the lab-testing process — is the same across both ranges.
CBD Oil Perth also carries CBG oil (cannabigerol) and CBN oil (cannabinol isolate, THC-free) at 1000mg, 3000mg, 6000mg and 12000mg. These are distinct cannabinoids, not variants of CBD. Browse the full product range for the complete catalogue.
All products are imported from EU Labs in Amsterdam and dispatched from Australia.
Which strength is right for me?
This is the question every label-reading guide has to address — and it has a careful answer.
Start low and follow the label serving. Every bottle has a suggested serving printed on the label. That figure is the manufacturer's recommendation for a typical adult. The standard starting point in the industry is to begin with the smallest serving shown and observe how you respond to the oil over several days before making any changes.
Compare mg/mL, not sticker price. A 3000mg bottle costs more than a 1000mg bottle, but the cost-per-mg is often lower at higher strengths. Work out the price-per-mg (divide the price by the total mg on the label) if value matters to you.
Consider spectrum. If you prefer to avoid all THC, broad-spectrum is the straightforward choice. If you want the full-plant profile including the trace THC present in legal hemp, full-spectrum achieves that.
For guidance beyond the label, speak to a healthcare professional. No guide — this one included — can responsibly recommend a specific mg figure for a specific person or purpose. A GP or pharmacist familiar with cannabinoid products is the right source for personalised guidance.

How to compare CBD oil strength between brands
When you are looking at products from multiple suppliers, four data points let you make a fair comparison:
1. mg per mL. As covered above: divide total mg by total ml. This is the only honest unit of comparison between bottles of different sizes.
2. Carrier oil. Most quality CBD oils use MCT oil (coconut-derived) as the carrier. The carrier affects texture and how the oil is absorbed; it is worth noting on any label you read. The CBD Oil Perth range uses MCT throughout.
3. Spectrum. Full-spectrum, broad-spectrum, CBG isolate, CBN isolate — these are compositionally different products. Comparing a broad-spectrum to a full-spectrum at the same mg/mL is an apples-to-apples strength comparison only; the cannabinoid profiles differ.
4. Certificate of Analysis (COA). A COA is a lab report from a third-party testing facility confirming what the product actually contains. Reputable suppliers make these available on request or publish them online. CBD Oil Perth products are third-party lab-tested by batch; COAs are available on request. If a supplier cannot produce a COA, consider that a material gap in transparency.

Is CBD oil legal in Perth, WA?
CBD oil for human use sits within the framework regulated by the Therapeutic Goods Administration (TGA) — the Australian government body responsible for therapeutic products. In practice, this means:
- Prescription CBD (medicinal cannabis) is accessible through an authorised prescriber or via the TGA's Special Access Scheme.
- Low-dose CBD products were rescheduled in 2021 to allow pharmacist-access without prescription at certain concentrations; uptake of this pathway remains limited and the range is narrow.
- Online CBD oil from overseas without a valid Australian import permit is not compliant with TGA rules.
The products stocked by CBD Oil Perth are imported and dispatched to customers across Perth, Fremantle, Mandurah, Joondalup, Bunbury and the wider Western Australia region. For the current regulatory position, the TGA website is the primary reference.
If you have questions about the regulatory status of a specific product, a pharmacist or your GP is the appropriate contact.
Frequently asked questions
What does 1000mg CBD oil mean? It means the entire 50ml bottle contains 1000mg of CBD. Divide 1000 by 50 and you get 20mg per millilitre. A standard 0.5ml dropper delivers 10mg per serve.
Which strength should I choose? Follow the label's suggested serving for the bottle you buy. If you are new to CBD oil, the 1000mg option is the entry-level strength, with each dropper delivering 10mg. For guidance on which strength suits your situation, speak to a healthcare professional.
Is a higher mg number always stronger? Only if the bottle size is the same. A 3000mg oil in a 50ml bottle (60mg/mL) is stronger than a 3000mg oil in a 100ml bottle (30mg/mL). Always calculate mg per mL before drawing conclusions from the headline number.
Where can I buy CBD oil in Perth? CBD Oil Perth ships to Perth and across Western Australia, including Fremantle, Mandurah, Joondalup and Bunbury. You can browse the full range of CBD oils or visit the homepage for more information about the store.
Can I get a Certificate of Analysis for my bottle? Yes. All CBD Oil Perth products are third-party lab-tested by batch. Contact the store at [email protected] to request a COA for your specific product.
What does the dropper scale on the bottle mean? The dropper inside the cap has graduated markings — typically lines at 0.25ml and 0.5ml. Most CBD oil labels base their suggested serving size on a 0.5ml fill. To get 0.5ml, squeeze the bulb, dip the dropper into the oil, and release the bulb until the liquid reaches the 0.5ml mark. This gives you a consistent serve each time. The how-to-use guide on this site covers dropper technique and storage in plain detail — useful reading if you are using CBD oil for the first time.
What does full-spectrum mean on the label compared to broad-spectrum? Both full-spectrum and broad-spectrum CBD oil are derived from whole-plant hemp extract. The label distinction refers to one thing: whether trace THC has been retained (full-spectrum, under 0.3% THC) or removed entirely (broad-spectrum, 0% THC). The CBD concentration, the MCT carrier, the 50ml bottle format and the third-party lab-testing are the same across both. Perth customers choosing between the two are making a compositional preference decision, not a quality decision.
