That link is $10 off 1 & 2. You get both for $49.95 (i.e., all 6 bottles).
There’ll be about 50 sets going out total.
Mostly to the “feel good” realm.
However, that’s not what the androstenone experiment is all about.
Androstenone is a very powerful, firey pheromone with some extreme upsides and downsides.
I’m hoping to “debug” it… to accentuate (or retain) most of the positives, and eliminate or reduce some of the negatives.
That’s been my blueprint with most of the “basic” pheromones. You find “debugged” rone in A314, debugged Alpha nol in Instant Openness, etc.
Furthermore, genetics pushes us to perceive our relationships as old and boring.
Sex, whether you like it or not, is all about reproduction, even if you view it as a recreational. Recreation is but a side effect of the primary goal of reproduction, not the other way around.
Nature sets up QUITE a few boobytraps to break us apart and keep the genes spread far and wide, including a woman’s “monthly relationship destroyer” (PMS).
And to spread that seed! 
To encourage survival and biological diversity.
Anyway, “plain old” androstenone (found in Turn Up The Heat, amongst other products) often adds a good deal of heat to an “old” relationship, but you sometimes have to time it well.
Long term partners usually expect you to be more of a rone man (a stable provider) than a -none man (a wham, bam, thank you man, sperm donator)… so you have to introduce it cautiously, preferably near her ovulation.
IFM helps SOME people to rekindle a sexual flame, too, but this effect isn’t as predictable as are it’s relaxation effects upon women. Also, it can have adverse effects on your own mental state – an unwanted mellowing, if nothing else.
Shine is a safe route, and should definitely rekindle some flame. At least the cuddlt, affectionate type.
TAF is experimental, but seems to play the role of a “second look” pheromone in some cases. Shuts down the brain’s filters, hotwires the Reticular Acviating System (the RAS), and allows people to look at things or people like they were looking at them for the very first time… valuable in some contexts… including this one.
If you ever have relationships problems OTHER than sex, A314 is good. I’ve gotten reports of it saving marriages (but NOT turning up the heat in bed). Fulfills a strong, personal “hero” role.
You’re welcome.
