i’ve asked this a couple of times, but no one answered 
is there anything special in IO + IH that there is not in CTTM2?
Nobody knows the exact recipe for sure except Androtics.
The main ingredient in IO is alpha nol. The main ingredient in IH is beta nol. There are other pheromones in small amount.
CTTM contains alpha nol and beta nol with other pheromones in small amount too.
no, i mean not the exact recipe
just the some extra knowledge maybe a little of TAA? or TAF? or something else maybe?
You’re asking the wrong people 
We are forum members, phero users… We’re not privy to info like what ingredients you get in the mixes other than the main components. Ratio’s, specific steering molecules etc…that’s info noone has access to.
IH is roughly 70:30% of beta:alpha
IO is roughly 30:70% of beta:alpha
CTTM2 is roughly 50:50 of beta:alpha
I say roughly because there are small amounts of steering molecules there too…
