What does the number on a CBD oil bottle actually mean? It is a question worth asking plainly before you buy. The short answer: the mg figure on the label is the total cannabinoid content inside the entire bottle — not per drop, not per dose, not per day. Everything else in choosing a CBD oil strength follows from that single fact. This guide walks through the arithmetic, the label language, and the full range of strengths available with delivery across Adelaide, SA and the rest of Australia.
What the milligram number actually means
The mg number printed on a CBD oil label — 1000mg, 3000mg, 6000mg, 12000mg — is a declaration of total contents, exactly the way a nutrition label states grams of protein per 100g. The number tells you how much cannabidiol is in the whole bottle. It says nothing about a single drop or a single dropper.
This matters because two bottles sitting next to each other on a shelf can both say 1000mg CBD oil and contain very different concentrations. If the first bottle is 50ml and the second is 100ml, the first is twice as concentrated despite the identical headline figure. Comparing mg alone without accounting for bottle volume leads to a wrong call every time.
The one calculation that cuts through all of that: divide the total mg by the total volume in ml. The result is mg per millilitre — the honest unit of comparison across any two products.
Per-mL concentration: the maths for our range
Every bottle in the CBD Oil Adelaide range is 50ml. That makes the arithmetic fixed and straightforward. Here is the full table:
| Label strength | Bottle volume | CBD per mL | Per 0.5ml dropper serve |
|---|---|---|---|
| 1000mg | 50ml | 20mg/mL | 10mg |
| 3000mg | 50ml | 60mg/mL | 30mg |
| 6000mg | 50ml | 120mg/mL | 60mg |
| 12000mg | 50ml | 240mg/mL | 120mg |
The dropper inside the cap typically holds 0.5ml when filled to the marked line. Multiply 0.5 by the mg/mL figure for your bottle and you have the amount per serve. At 3000mg that is 30mg per half-dropper; at 6000mg it is 60mg in the same physical quantity of oil. The bottle size stays constant; only the concentration changes.
If you are comparing our bottles to a product from another supplier, apply the same formula. A 1000mg bottle that is only 30ml works out to 33mg/mL — a stronger concentration than the same label on a 50ml bottle at 20mg/mL. The label headline is not the comparison point. mg per mL is.
Our full CBD oil strengths: 1000mg to 12000mg
CBD Oil Adelaide carries four strengths across two spectrum types. All are 50ml, MCT-based (coconut-derived), and third-party lab-tested by batch. A Certificate of Analysis is available for any batch — email [email protected] with your batch number and we will send it.
Full-spectrum range — trace THC under 0.3%
- CBD oil 1000mg — Full Spectrum — 20mg/mL, a 0.5ml serve delivers 10mg. From $89.95.
- CBD oil 3000mg — Full Spectrum — 60mg/mL, 30mg per 0.5ml serve. From $220.00.
- CBD oil 6000mg — Full Spectrum — 120mg/mL, 60mg per 0.5ml serve. From $390.00.
- CBD oil 12000mg — Full Spectrum — 240mg/mL, 120mg per 0.5ml serve. From $585.00.
Broad-spectrum range — 0% THC
- CBD oil 1000mg — Broad Spectrum — 20mg/mL, 10mg per serve. From $89.95.
- CBD oil 3000mg — Broad Spectrum — 60mg/mL, from $220.00.
- CBD oil 6000mg — Broad Spectrum — 120mg/mL, from $390.00.
- CBD oil 12000mg — Broad Spectrum — 240mg/mL, from $585.00.
The difference between the two spectrum types is one fact: full-spectrum keeps a legal trace of THC (under 0.3%, confirmed by the batch COA); broad-spectrum has that THC removed entirely (0% THC on the lab report). The cannabidiol content, the MCT carrier, the 50ml bottle, and the batch-testing process are identical across both ranges. Choosing between them is a compositional preference, not a quality decision. The full-spectrum CBD oil and broad-spectrum CBD oil pages explain each type in detail.
CBG and CBN: the other strengths in the range
The CBD Oil Adelaide range in Adelaide does not stop at CBD. Two additional cannabinoid oils are available at the same four strengths:
CBG oil (cannabigerol) — a single-cannabinoid oil carrying cannabigerol, the compound the hemp plant synthesises before converting it into other cannabinoids. Available at 1000mg, 3000mg, 6000mg and 12000mg in 50ml MCT bottles. The CBG oil page covers the chemistry; the CBG oil 1000mg is the entry point.
CBN oil (cannabinol) — a THC-free isolate carrying a single cannabinoid in the same MCT base. Available at 1000mg, 3000mg, 6000mg and 12000mg. See the CBN oil page for a plain breakdown, or go straight to the CBN oil 1000mg. The mg figures on CBG and CBN labels work by the same maths: total cannabinoid in the whole 50ml bottle.

Value comparison: price per mg across the range
A higher-strength bottle costs more upfront. Whether it costs more per milligram of CBD is a separate question — and the answer is no. The cost-per-mg falls as the strength goes up.
| Strength | Price | Price per mg |
|---|---|---|
| 1000mg | $89.95 | 9.0 cents/mg |
| 3000mg | $220.00 | 7.3 cents/mg |
| 6000mg | $390.00 | 6.5 cents/mg |
| 12000mg | $585.00 | 4.9 cents/mg |
Buyers who use CBD oil regularly often find the 3000mg or 6000mg option offers a more economical price-per-mg over time, compared with buying the 1000mg bottle repeatedly. The per-mg figure is the only honest way to compare value across different strengths — just as the per-mL concentration is the only honest way to compare two products from different brands.

How to read the label serving guidance
Every bottle in the CBD Oil Adelaide range carries a suggested serving size printed on the label. That figure is the manufacturer's recommendation for a standard adult. It is not medical advice. It is a starting reference — the same kind of guidance you see on any supplement or health product.
Start with the label serving and the lowest strength. The standard approach in the industry is to begin at the label's smallest suggested amount and observe how you respond over several days. There is no universal figure that applies to every person; the label serves as the first reference point.
Do not interpret mg comparisons as dosing guidance. The maths in this guide — mg/mL, price-per-mg, dropper volume — are label-reading tools, not dosing recommendations. For guidance on what strength or amount is appropriate for a specific person or purpose, a GP or pharmacist familiar with cannabinoid products is the right contact. No content on this site substitutes for that conversation.
The dropper technique matters. The dropper typically has a marked line at 0.5ml. Squeeze the rubber bulb before lowering the dropper into the oil, release slowly until the liquid climbs to the 0.5ml mark, then remove. That gives you a consistent measured serve every time. The guide to using CBD oil on this site covers dropper reading and storage in plain language.
Is CBD oil legal to buy in SA?
CBD oil sits within the national regulatory framework administered by the Therapeutic Goods Administration — the Australian body responsible for therapeutic goods. The rules apply uniformly across every state and territory, including South Australia. Key points:
- In 2021 the TGA rescheduled low-dose cannabidiol (up to 150mg per day) as a pharmacist-only Schedule 3 medicine, creating a lawful over-the-counter pathway. In practice, approved products through this route are limited and the range is narrow.
- Higher-strength or prescription-grade medicinal cannabis products require a doctor's authorisation through separate TGA pathways.
- Importing unregistered CBD products from overseas without a valid Australian import permit is not compliant with TGA rules.
CBD Oil Adelaide imports its range into Australia and dispatches from within the country. We describe every product by composition only and make no health claims. The TGA website carries the current rules and any updates.
Our oils are for adults 18 and over and are not suitable for anyone pregnant or breastfeeding. If you are taking regular medication, speak with your GP before adding any hemp-derived oil.

Frequently asked questions
What does 1000mg CBD oil mean? The entire 50ml bottle contains 1000mg of cannabidiol. Divide 1000 by 50 and the concentration is 20mg per millilitre. A 0.5ml dropper serve delivers 10mg. The figure is about what the bottle holds — it is not a dose recommendation.
Is a 3000mg bottle three times stronger than a 1000mg bottle? Yes — but only when the bottle size is the same (both 50ml). A 3000mg in 50ml gives 60mg/mL; a 1000mg in 50ml gives 20mg/mL. If the bottle volumes differ, always calculate mg per mL before drawing any conclusion from the headline number.
What is the difference between full-spectrum and broad-spectrum strength? The mg strength works identically for both — it is the total cannabinoid content in the whole bottle. The spectrum label tells you about THC: full-spectrum retains trace THC under 0.3%; broad-spectrum has it removed (0% THC). Same concentration maths; different composition. See the full-spectrum CBD oil and broad-spectrum CBD oil pages.
Which strength offers the best value? At the 12000mg level, the price works out to roughly 4.9 cents per mg compared with 9.0 cents per mg at 1000mg. Higher-strength bottles cost more upfront but less per milligram. The right choice depends on how much oil you use; the price-per-mg table above gives the comparison at a glance.
Can I get a Certificate of Analysis for my bottle? Yes. All CBD Oil Adelaide products are third-party lab-tested by batch. Email [email protected] with the batch number on your bottle and we will send the matching COA.
