Questions on different strengths of phero

I notice that many different pheros, lets say like Instant openness, come in different “strengths”. (This one from 1x-4x)
Now I know that more is not always better, but would getting a higher strength phero save on sprays and make a bottle last longer?

With regular strenth, I’ve seen many people on the forum use 2-3 sprays in some situations.
Lets say one spray of IO has x mcg of phero. 2 sprays and you have 2x mcg phero on you.
So with, say, a twice-as-strong bottle of IO, you would have 2x mcg phero on you with only ONE spray. Saving it, a little.

So it might be shrewd to buy a higher strength and use half as many squirts.
If you buy, say, a 4x, then you would need just a smidgeon to achieve the same effects as a 1x, making the bottle last a looong time.

Is my thinking correct?

Yes your thinking is correct once you are sure of your dosage.

Your pretty safe with the womens or unisex products though, The men need to worry more because of the OD effect with anone products. So I dont suggest jumping to double ammo for them unless the tested it first or are over 40.

I would say with socials like Ishine IO IH you can jump to 2X. Everyone uses at least 2 sprays of the normal strength.
