I’m not too familiar with most LS products but from what I gather Scent of Eros is a combination of AndrosteRone and Androstenol.
Judging by it’s ingredients I would guess at the right dosage it’ll give off a friendly alpha guy vibe.
NPA on the other hand is mostly Androstenone and should be used in very small amounts. The reason it’s in a dropper is because just a drop is usually more then enough. I’ve never tried it myself but have read both good and bad things about it (mostly pertaining to potency).
Both Turn Up The Heat and Ammo also contain Androstenone.
The former being 2.5mcg of straight -none and the latter a mix of 2.5mcg plus other social steering agents.
The thing to remember is that Androstenone products while potentially very effective come with a OD risk.
So less really may end up being more.
Something you might find especially true given the fact that you’re 24 and probably produce a fair amount of it yourself.
I’m sure you’ll get the hang of all this in no time.
