Yes, you can find nic shots in different VG/PG blends to match your e-liquid and device preferences.

One 10ml nic shot with 18mg strength added to a 50ml shortfill usually makes the final mix 3mg of nicotine.

It's not required, but letting it sit for a few hours or overnight can help the nicotine blend better with the flavour.

Nic shots are made for nicotine-free shortfills. You shouldn’t add them to regular 10ml e-liquids that already contain nicotine.

No, nic shots can vary in strength, VG/PG ratio, and even type, like freebase or nic salt, so choose one that suits your vaping style.
