Agent P is a full bodied blend of exotic fruits and creams rounded out by a hint of strawberry. The result is similar to a tropical milkshake unlike anything you've ever tasted.
Exotic fruits could be Pineapple, Coconut, Banana, or all 3, and then the hint of Strawberry.
If it has any Pineapple tho you should be able to pick up on it.
Banana & Coconut do work with Strawberry BTW, I'd try some INW Shisha Strawberry at 0.5-1% to start, for a hint.
Funny but INW Cherimoya is a blend of fruits, but don't think they're considered tropical
(hard to blend several fruits all together and get them balanced proper)
Creams are fairly easy to test out:
TFA Dairy Milk 1-2%
FW Milk 3-5%
Hangsen Cream 0.5%
TFA DX Bavarian or DX Sweet Cream 1-3%
TFA/CAP Vanilla Bean Ice Cream?, may help with the milkshake but...
10% NF Organic Malt + 1-2% TFA Malted Milk works OK for a Malt/Shake base, optionally add in some Cream/Ice Cream.
Doubt they're using any Custard, but a Fruity Custard isn't going to be a bad thing to vape.
And sometimes just adding 1% CAP Vanilla Custard really helps some mixes to shine IMO.
Never had the original so just a bit of brainstorming.
