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 HHC combination in Gasline differ from a single-cannabinoid Delta-8 oil?

A pure Delta-8 THC oil delivers one dominant psychoactive compound with a relatively predictable onset and duration curve. Gasline layers Delta-8 THC at approximately 44.6–45.9% and HHC at approximately 29–31% of formula, and the combination produces a meaningfully different experience than either compound alone. HHC (hexahydrocannabinol) is a hydrogenated THC derivative with its own CB1 binding profile, and its presence alongside Delta-8 THC tends to extend duration and add depth to the body-effect component in ways that a Delta-8-only oil typically does not sustain. The CBD content at approximately 10% smooths the onset curve and reduces abruptness at the start of the session without substantially cutting into overall potency at these ratios. Most experienced users describe the combined effect as heavier and longer-lasting than single-cannabinoid Delta-8, with a slower taper at the end of the session.

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 phytocannabinoid with a CB1 receptor binding affinity substantially higher than Delta-9 THC. In the Gasline formula, it is present at approximately 0.68–0.86% of total volume — a small percentage on paper, but a disproportionate contributor to the perceived intensity of the overall blend given its binding characteristics. The practical guidance is straightforward: start with one conservative draw, wait a full 15 minutes, and assess before adding more. This applies even to experienced consumers who regularly use high-potency Delta-8 or HHC products, because the THC-P amplification effect can catch you at a different ceiling than you’re accustomed to. Treat this formula’s effective potency as one tier higher than its listed percentages suggest when you are calibrating your first few sessions.

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 individual consumption habits, but a reasonable estimate for a single-draw-per-session consumer at moderate draw length is 50–100 sessions per syringe. Consumers who take multiple draws per session will see proportionally fewer sessions. At $9.99 per syringe, the per-session cost is competitive with or lower than most pre-filled disposables at comparable cannabinoid concentrations, particularly given that Gasline’s total cannabinoid content of 92.0–93.8% is on the high end of what’s available in this format. The refillable device also means hardware cost is a one-time purchase rather than a cost embedded in every unit, which improves the economics further over time.

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 for use with the URB 2mL Gasline refillable device, which the buyer fills and assembles independently. It is not a standard 510-thread cartridge and does not attach directly to a 510-thread battery. If you own other refillable devices that accept thick distillate oil through a manual fill port, the syringe can function as a fill tool for those as well, but compatibility is device-specific and is not guaranteed outside the Gasline device. The device-only option at $6.99 is available on this page if you want to pick up compatible hardware without committing to a bundle. Staff at D8 Austin’s store at 9231 W Parmer Ln UNIT 102, Austin, TX 78717 can address hardware compatibility questions before you purchase.

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, the oil’s effects typically onset within 5–15 minutes of the first draw — considerably faster than edibles or tinctures. The THC-P content means effects can continue building past that initial window, in some cases up to 30 minutes after the first draw, which makes early re-dosing the most common mistake with this formula. Duration for experienced consumers generally ranges from one to three hours depending on draw count, individual metabolism, and baseline tolerance. Plan your session before you start — this is not a product to use immediately before you need to drive, operate equipment, or be fully functional in any professional or safety-sensitive context.

What makes buying Gasline through D8 Austin different from buying directly from URB?

D8 Austin is a multi-brand retailer, which means the Gasline oil and device sit on the shelf next to comparable high-potency formats from other brands — and you can compare them directly, in person, before committing to a purchase rather than ordering blind. Every product D8 Austin stocks has cleared an internal lab documentation review before it reaches the floor; if the COA doesn’t support the label claims, it doesn’t get carried. For buyers in Austin, in-store pickup at 9231 W Parmer Ln UNIT 102, Austin, TX 78717 means no shipping wait and the ability to ask product-specific questions before you buy. For buyers outside Austin, D8 Austin ships the Gasline syringe and device to all states where Delta-8 THC and HHC products are currently eligible, and the Lab Results link on this page connects you directly to the third-party documentation for the specific product you’re purchasing.
