Strongest CBD products in Australia — what concentration actually means
Searching for the “strongest CBD oil” in Australia returns a mix of products with large milligram numbers, claims about potency and very little explanation of what those numbers mean. “Strongest” in the context of cannabidiol (CBD) oil has one measurable definition: milligrams of cannabidiol per millilitre of oil (mg/mL). That single figure determines how much CBD each drop delivers. Everything else — the headline total milligrams, the bottle size, the brand’s marketing — is secondary to that number.
This article covers how CBD concentration works, which products in the EU Labs range deliver the highest cannabinoid content per millilitre, when high-concentration products make practical sense and how Australian TGA scheduling interacts with product strength. For a broader buying framework, the best CBD oil Australia guide covers the five quality criteria that matter more than strength alone.
Concentration is the only meaningful measure of strength
The headline milligram figure on a CBD oil label — 3000mg, 6000mg, 12000mg — only tells part of the story. A 3000mg product in a 30 mL bottle delivers 100 mg/mL. A 3000mg product in a 50 mL bottle delivers 60 mg/mL. Same headline number, very different strength per drop.
To calculate concentration from a label: divide total milligrams by bottle volume in millilitres. The result is mg/mL. A glass dropper delivers approximately 20 drops per millilitre, so divide mg/mL by 20 to get milligrams per drop. That figure — milligrams per drop — is the number that matters when comparing product strength in practical terms.
The concentrations explained article covers this maths in full. The 3000mg vs 12000mg comparison applies it to the two most common EU Labs CBD oil sizes.
The strongest CBD oils in the EU Labs range
The EU Labs range includes CBD oils at two concentration levels: 3000mg in 50 mL (60 mg/mL) and 12000mg in 50 mL (240 mg/mL). Both are available in full spectrum and broad spectrum.
The EU Labs CBD Oil 12000mg Full Spectrum delivers 240 mg of cannabidiol per millilitre — approximately 12 mg per drop. The 12000mg Broad Spectrum delivers the same concentration with THC removed below detectable limits.
By comparison, the 3000mg Full Spectrum delivers 60 mg/mL — approximately 3 mg per drop. The 12000mg products deliver four times as much cannabidiol per drop from the same dropper volume.
Both full spectrum and broad spectrum are available at 12000mg. The difference between them is THC content, not CBD concentration. Full spectrum retains trace THC below 0.3%; broad spectrum removes it. The full spectrum vs broad spectrum comparison explains when each makes sense. The broad spectrum article covers the zero-THC formulation specifically.
Strongest CBG and CBN oils in Australia
EU Labs also produces cannabigerol (CBG) and cannabinol (CBN) oils at matching concentration levels. For those looking for the highest cannabinoid content per millilitre beyond CBD, both cannabinoids are available at 12000mg in 50 mL.
The EU Labs CBG Oil 12000mg delivers 240 mg of cannabigerol per millilitre — the same concentration as the strongest CBD oil in the range. The EU Labs CBN Oil 12000mg delivers 240 mg of cannabinol per millilitre.
For a breakdown of what CBG and CBN are and how they differ from CBD, the CBD vs CBG vs CBN comparison covers each cannabinoid’s profile. What is CBG oil specifically is covered in the CBG oil article, and the CBN oil article covers cannabinol.
Why some people choose high-concentration products
High-concentration CBD oil is not “better” by default — it suits specific situations where lower concentration creates practical problems.
Larger serving sizes. Some people take larger daily amounts of CBD oil. At 60 mg/mL (3000mg), a 60 mg daily serving requires 1 mL — one full dropper. At 240 mg/mL (12000mg), the same 60 mg requires just a quarter dropper. A lower volume per serving is easier to measure accurately and means the bottle lasts longer at the same daily amount.
Cost per milligram. Higher concentration products typically cost less per milligram of CBD than lower concentration alternatives from the same brand. If the daily routine requires a fixed amount of cannabidiol, buying it at 240 mg/mL costs less than buying the same total milligrams at 60 mg/mL. The CBD oil pricing guide covers cost-per-mg comparison methodology.
Fewer drops to measure. A serving that requires 15–20 drops at 3000mg requires just 3–5 drops at 12000mg. Fewer drops means faster administration and less chance of miscounting. For people using CBD oil twice daily, this adds up over time.
Precision at higher amounts. High-concentration oils give more granular control when a vet or healthcare professional recommends a specific milligram amount. A quarter-dropper, half-dropper and full-dropper from a 12000mg product deliver clearly defined, easily repeatable amounts.
TGA scheduling and concentration in Australia
Australia’s Therapeutic Goods Administration (TGA) regulates CBD products under two schedules. Schedule 3 (pharmacist-only, no prescription required) permits CBD products with a maximum of 150 mg per day. Schedule 4 (prescription required) covers higher daily amounts.
This scheduling is based on daily dose, not product concentration. A 240 mg/mL product is not inherently outside Schedule 3 — it depends on how much of it is used per day. A quarter-dropper from a 12000mg product (approximately 12 mg) is well within Schedule 3 limits. The schedule limits the daily amount consumed, not the concentration of the product itself.
Higher-concentration products accessed under Schedule 4 with a prescription allow daily amounts above 150 mg. The CBD oil legality article covers the full TGA scheduling framework, and the buying CBD in Australia guide explains the access pathways in practice.
What to verify regardless of concentration
A high concentration means nothing without verified cannabinoid content. A CBD oil labelled 12000mg should test at 240 mg/mL (within ±10–15%) on an independent third-party certificate of analysis (COA). Without a batch-specific COA, the concentration claim is unconfirmed.
EU Labs publishes batch-specific COAs for every product in the range — the batch number on the bottle matches the corresponding lab report. The COA covers cannabinoid potency (confirming the stated mg/mL), THC levels, heavy metals, pesticides, residual solvents and microbial contamination. The third-party lab testing article explains each panel. The lab report guide walks through how to interpret the results.
Extraction method also matters. EU Labs uses supercritical CO₂ extraction across the entire range — no residual solvents, no chemical processing steps that could degrade cannabinoid content. The COA’s residual solvents panel confirms this for each batch.

The range ships nationally to Sydney, Melbourne, Brisbane, Perth, Adelaide, Darwin, Townsville and all other Australian locations.
Frequently asked questions
What is the strongest CBD oil available in Australia?
By concentration, the strongest CBD oils in the EU Labs range are the 12000mg products at 240 mg/mL — delivering approximately 12 mg of cannabidiol per drop. Both full spectrum and broad spectrum versions are available at this concentration. Strength is measured in mg/mL; total milligrams without bottle volume is an incomplete figure.
Is higher concentration CBD oil better?
Not inherently. High-concentration CBD oil suits people who take larger daily amounts, want lower volume per serving, or are comparing cost per milligram. For people starting with CBD oil for the first time, the 3000mg product at 60 mg/mL offers more precise control over small amounts. The beginner’s checklist covers product selection for first-time buyers.
How do I calculate CBD concentration from a label?
Divide total milligrams by bottle volume in millilitres. A 12000mg product in a 50 mL bottle delivers 240 mg/mL. Divide that by 20 (approximate drops per mL from a glass dropper) to get milligrams per drop — approximately 12 mg. The concentrations article covers the full calculation with worked examples.
Does the strongest CBD oil have more THC?
No. THC content is determined by the spectrum type — full spectrum vs broad spectrum — not by CBD concentration. The EU Labs 12000mg Full Spectrum contains trace THC below 0.3%, the same percentage as the 3000mg Full Spectrum. The 12000mg Broad Spectrum removes THC below detectable limits regardless of the higher CBD concentration.
Is CBG or CBN stronger than CBD?
“Stronger” applies to concentration (mg/mL), not to comparative effects between cannabinoids. EU Labs CBG and CBN oils are available at the same 240 mg/mL concentration as the strongest CBD oil in the range. What each cannabinoid does in the body differs — the CBD vs CBG vs CBN article covers each compound’s profile.
