URB Gasline Delta-8 THC Oil Syringe + Refillable Device

Lab Results

• Berry Gelato (Indica) — Berry Gelato opens with ripe mixed berry sweetness — blueberry and blackberry in roughly equal weight — before settling into a smooth dessert-cream finish on the exhale. The indica classification keeps the overall character round and unhurried, with no sharp resinous edges on the draw. This is the most accessible flavor in the lineup for consumers who want a clean, sweet, low-funk expression at this potency level.
• Black Cherry Fizz (Hybrid) — Dark, ripe cherry leads the inhale with a faint effervescent brightness on the backend that keeps the overall profile from reading as heavy or syrupy. A light tartness in the mid-draw adds contrast — similar to the push-pull in a well-made cherry soda — before a short, clean finish. The hybrid classification places this squarely between the grounded warmth of Berry Gelato and the more active energy of the sativa option.
• Gas Berry (Hybrid) — Gas Berry runs two distinct flavor elements in sequence rather than blending them: ripe berry sweetness on the inhale transitions clearly into an earthy, fuel-tinged backend during the exhale. The contrast between the two is the defining characteristic of this profile, making it a strong option for consumers who prefer more complex, terp-forward vapor over single-note fruit expressions.
• Guava Gelato (Hybrid) — Tropical and smooth, Guava Gelato delivers ripe guava over a creamy gelato-style finish with none of the sharp citrus or fermented tropical funk some guava profiles carry. The mellow hybrid classification behind this variant keeps the experience flowing and even rather than pushing distinctly toward relaxation or stimulation. This profile tends to suit consumers who want heavier tropical fruit character without the gassy or diesel elements present elsewhere in the lineup.
• Juicy Fruit (Hybrid) — Bright and candy-forward, Juicy Fruit delivers a recognizable sweet tropical-citrus sweetness with a clean, short finish that doesn’t linger heavily on the exhale. The hybrid formulation behind this profile tilts toward active engagement over deep relaxation, making it a workable choice for afternoon or social use for high-tolerance consumers.
• NYC Diesel (Sativa) — Citrus-forward with a sharp, piney diesel character that builds through the draw and dominates the exhale, NYC Diesel is the most complex and savory profile in the Gasline lineup. A grapefruit or tangerine note arrives first before giving way to the characteristic fuel undertone that defines diesel-profile strains. This is the go-to option within this oil lineup for consumers who want a more stimulating, terp-forward experience consistent with sativa-oriented selection.

• Fill the empty Gasline device with the 1mL syringe
• Assemble the hardware securely
• Let the oil settle if needed before the first draw
• Start with small pulls, not deep, continuous inhales
• Keep the device upright when possible
• If the oil feels thick, giving it a little time to settle can help with consistency. For storage, keep both the syringe and device in a cool, dry place away from direct heat or sunlight. That helps preserve texture, flavor, and performance over time.

How does the Delta-8 THC and mixed cannabinoid blend in Gasline differ from a single-cannabinoid Delta-8 oil?

A pure Delta-8 THC oil delivers one dominant cannabinoid with a relatively predictable onset and duration curve. Gasline combines Delta-8 THC at approximately 44.6–45.9% with a complementary mixed cannabinoid blend representing approximately 29–31% of the formula, creating a more layered experience than Delta-8 alone. The additional cannabinoids contribute depth, body presence, and extended duration, helping the effects feel fuller and more sustained throughout the session. CBD at approximately 10% further smooths the overall experience, helping create a balanced onset without significantly reducing potency. Most experienced consumers describe the result as a richer and longer-lasting experience than a single-cannabinoid Delta-8 formulation.

What does THC-P contribute to this formula, and how should it affect how much oil I use per session?

THC-P (tetrahydrocannabiphorol) is a naturally occurring cannabinoid known for its strong receptor activity. In the Gasline formula, it is present at approximately 0.68–0.86% of total volume — a relatively small percentage that can still contribute meaningfully to the perceived intensity of the blend. For that reason, the best approach is to start with one conservative draw, wait a full 15 minutes, and evaluate the effects before taking more. Even experienced consumers who regularly use high-potency cannabinoid products may find the overall experience stronger than expected. Consider the formula’s effective potency to be higher than the percentages alone might suggest when determining your ideal serving size.

How many sessions should I expect from one 1mL syringe, and how does that compare to a standard disposable?

A 1mL syringe contains approximately 1 gram of oil. Actual session yield depends on draw length, draw frequency, and personal consumption habits, but a reasonable estimate for moderate use is approximately 50–100 sessions per syringe. Consumers who take multiple draws per session will naturally see fewer total sessions. At $9.99 per syringe, the per-session cost can compare favorably to many pre-filled disposables with similar cannabinoid concentrations. With total cannabinoid content ranging from 92.0–93.8%, Gasline sits toward the higher end of the potency spectrum for this format. Because the device is refillable, hardware becomes a one-time purchase rather than a recurring expense built into every disposable unit.

Will the Gasline syringe work with vape hardware I already own, or does it require the URB device?

The Gasline syringe is a blunt-tip refill applicator designed primarily for use with the URB 2mL Gasline refillable device, which users fill and assemble independently. It is not a standard 510-thread cartridge and does not attach directly to a 510-thread battery. Some refillable devices that accept thick distillate oil through a manual fill port may also be compatible, though compatibility varies by device and is not guaranteed outside the intended URB platform. The device-only option is available separately for customers who need compatible hardware.

How quickly do effects begin when this oil is used with a vaporizing device, and how long should I plan for?

When used with a compatible vaporizing device, effects typically begin within 5–15 minutes of the first draw, which is considerably faster than edibles or tinctures. Because THC-P is included in the formulation, effects may continue building for up to 30 minutes after the initial inhalation. As a result, taking additional draws too quickly is one of the most common mistakes among new users. Duration generally ranges from one to three hours depending on dosage, metabolism, tolerance, and individual response. Users should avoid driving, operating machinery, or engaging in safety-sensitive activities while experiencing cannabinoid effects.

What makes buying Gasline through D8 Austin different?

As a multi-brand retailer, D8 Austin offers customers the ability to compare products across multiple manufacturers rather than being limited to a single brand ecosystem. Products are reviewed alongside supporting documentation before being added to inventory, allowing shoppers to evaluate options in person. Local customers can take advantage of in-store pickup and product guidance, while online customers can access third-party laboratory documentation through the Lab Results section associated with the product listing.
