3. Close and shake
Put the cap and dropper back on. Shake vigorously for at least 1 minute to homogenise the mix.
4. Steep for the recommended time
Follow the steeping time indicated on the product page. Store the bottle in a cool, dark place while it rests.

LongFill Aroma 10/20ml nicotine table
This format has only 10ml of free space, so the mix is completed with one single 10ml addition.
| Approx. final nicotine | What to add | Extra base | Total added |
|---|---|---|---|
| 0 mg/ml | 10ml of 0mg base or 0mg booster | 10 ml | 10 ml |
| 5 mg/ml | 1 Nic Shot Booster at 10mg/ml | 0 ml | 10 ml |
| 10 mg/ml | 1 Nic Shot Booster at 20mg/ml | 0 ml | 10 ml |
Final nicotine depends on the strength of the Nic Shot Booster used. If you add 10ml at 20mg/ml into a final 20ml bottle, the approximate result is 10mg/ml.
Approximate VG/PG table for LongFill Aroma 10/20ml
Reference calculated assuming the 10ml of aroma is 100% PG. If the manufacturer provides a different composition, always follow that information.
| What you add in the 10ml free space | VG added | PG added | Approx. final VG/PG |
|---|---|---|---|
| 50VG/50PG base or Nic Shot Booster | 5 ml | 5 ml + 10 ml aroma | 25VG / 75PG |
| 60VG/40PG base or Nic Shot Booster | 6 ml | 4 ml + 10 ml aroma | 30VG / 70PG |
| 70VG/30PG base or Nic Shot Booster | 7 ml | 3 ml + 10 ml aroma | 35VG / 65PG |
| 80VG/20PG base or Nic Shot Booster | 8 ml | 2 ml + 10 ml aroma | 40VG / 60PG |
| Only VG in the 10ml free space | 10 ml | 10 ml aroma | 50VG / 50PG |
Because this format starts with 10ml of aroma in a final 20ml bottle, the mix remains more PG-heavy if the aroma is PG-based. Always check the product page and the device you plan to use.
