2500mg CBD-Rich Tincture | Maximum Strength Broad Spectrum | Zero THC

Maximum Strength. Scientifically Standardized. Zero THC.

cbdDR's 2500mg CBD-Rich Tincture is our highest-potency broad spectrum formulation — designed for experienced cannabinoid users, those with higher body weight, or those who have titrated up from our 1000mg formulation and require greater cannabinoid concentration per serving. At ~83mg of cannabinoids per 1ml serving, this is one of the most potent standardized broad spectrum CBD tinctures available.

Developed in-house by botanical scientist Matthew Scott, who has been formulating cannabinoid products since 2014. Not white-labeled. Not a commodity extract. A precision formulation engineered to deliver consistent, verified cannabinoid concentrations in every bottle.

Formulation Specifications

• Total Cannabinoids: 2500mg per 30ml bottle
• Primary Cannabinoid: CBD (Cannabidiol) — ~2080mg
• Supporting Cannabinoids: CBG, CBN, CBC — ~140mg each
• Serving Size: 0.5–1ml sublingual
• Servings Per Bottle: ~30–60
• Cannabinoids Per 1ml Serving: ~83mg
• Cannabinoids Per 0.5ml Serving: ~42mg
• THC: Zero — non-detected on every batch COA
• Carrier: MCT Oil (coconut-derived)
• Administration: Sublingual (under tongue, hold 60–90 seconds)

Who This Formulation Is For

• Experienced cannabinoid users who have established a baseline with lower-potency formulations
• Individuals with higher body weight requiring greater cannabinoid concentrations for equivalent effect
• Those seeking maximum cost-per-mg efficiency — at $50 for 2500mg, this delivers significantly lower cost per mg than the 1000mg formulation
• Users who prefer less frequent dosing with higher per-serving potency

The Science Behind Maximum Potency

Cannabinoid dose-response relationships are not linear. Research suggests that higher doses of CBD may engage additional receptor pathways and produce different pharmacological profiles than lower doses. The 2500mg formulation is designed for users who have completed the titration process and identified their optimal dose at a level that requires higher cannabinoid concentrations per serving.

The broad spectrum profile — CBD supported by CBG, CBN, and CBC — ensures the entourage effect is preserved at maximum potency. Each supporting cannabinoid contributes distinct receptor interactions: CBG via CB1/CB2 agonism, CBN via CB1 partial agonism, CBC via TRPV1/TRPA1 activation and anandamide reuptake inhibition.

Sublingual Bioavailability

Sublingual administration delivers cannabinoids directly into the bloodstream through the sublingual mucosa, bypassing first-pass liver metabolism. Peer-reviewed research (Millar et al., 2019) estimates sublingual CBD bioavailability at 20–35%. At 83mg per serving, effective systemic delivery is estimated at 17–29mg CBD reaching circulation per dose — significantly higher than equivalent oral ingestion.

Third-Party Testing

Every batch is tested by an ISO/IEC 17025-accredited independent laboratory for cannabinoid potency, heavy metals, pesticides, residual solvents, and microbials. Results are published batch-by-batch in our Batch Database.

Available Flavors

• Natural (unflavored)
• Chocolate Mint
• Mint
• Milk Chocolate
• Citrus

Suggested Use

Start with 0.5ml under tongue. Hold 60–90 seconds. Swallow. Titrate to 1ml based on individual response. Recommended for users already familiar with cannabinoid dosing. New to cannabinoids? Start with the 1000mg CBD-Rich Tincture.
