Looper Booster Shot Syringe 3G

The Looper Booster Shot is a 3 gram syringe of THC-A distillate built to refill the Looper 3ML Refillable Device. Instead of throwing away a disposable when it runs out, you keep the hardware and reload it. One syringe fills the 3ML device once, all the way.

Every Booster Shot in this collection is a multi-cannabinoid blend in a 3 gram graduated syringe, with a mild-to-strong potency scale printed on each carton.

Which Device Does It Fit?

The Booster Shot is made for the Looper 3ML Refillable Device. The syringe holds 3 grams, the device holds 3ml, so one shot equals one full refill.

It is not designed for Looper's sealed disposables. The Lifted Series XL, Melted Series XL and Live Badder disposables are closed units and are not meant to be opened or refilled.

How to Use a Looper Booster Shot

These are the manufacturer's own instructions, printed on the carton:

Leave the cap screwed on. Hold the centre of the syringe under running hot water for 20 to 30 seconds. Cold distillate is too thick to move.
Remove the cap and remove the mouthpiece from the 3ML device to expose the fill port.
Seat the tip of the syringe into the port, keeping the device upright.
Press the plunger slowly. Going fast pushes air into the chamber and causes dry hits.
Stop below the fill line. Overfilling forces distillate into the airway and leaks.
Replace the mouthpiece and wait 10 to 15 minutes before the first draw, so the coil saturates.

Do not eat. Not for ingestion. The Booster Shot is a refill for a vaporizer device only.

If you are new to refilling, our Looper how-to guide walks through opening the device and troubleshooting.

Why Refill Instead of Replacing

A disposable is one purchase for one tank. The 3ML device plus a Booster Shot separates the two: you buy the hardware once and reload it as many times as you want. It also means you can switch strains without buying a new unit, which is the part most people miss.

Several of these strains also exist as sealed Looper disposables. If you would rather not refill, browse Looper for the full range.

Looper is not the only brand making refills. See every THCA syringe we carry, including 2 gram terp sauce options from Mellow Fellow, if you want to compare formats before committing to one.

The Other Use: Making a Hash Hole

Refilling a device is not the only thing a graduated syringe is good for. The same 3 grams will build six or seven hash holes — infused joints with a solid core of concentrate running down the middle, which burn slower and hold their flavor to the last draw.

The Booster Shot suits this better than most concentrates for two reasons. The graduations on the barrel let you lay a consistent 0.3 to 0.5 grams per joint instead of guessing, and at $16.95 for 3 grams it is the cheapest way to practice a technique that takes a few attempts to get right.

Can you use a Booster Shot to make a hash hole?
