A list of the different types of pheromones is found here on wikipedia. What I think we see in humans is information pheromones, and possibly a very weak version of sex pheromones.
That list is intriguing, and almost certainly incomplete/incorrect.
Regarding the topic at hand: I have been monitoring various peer-reporting communities for some time, lately also conducting some of my own tentative bioessaying, and am left in no doubt as to the efficacity of topically applied neurosteroids. In fact I'm quite surprised that there's been little discussion of these compounds to date here.
Sex pheromones have been quite heavily studied, but neuroactive steroids in general, and their regulatory function within the endocrine system, are somewhat less well understood.
As per usual with novel substances and such similar, there appears at present to be something of a chasm between the published literature on this subject (peer reviewed), and the information which can be gleaned from forums/blogs and so on (peer reported).
There are many 'putative pheromones' (and no doubt there are countless others yet to be synthed/isolated), but at this time, there are around 20 (publically) known human pheromones, some of which function as sex pheromones.
Regarding the latter:
Young, fit athletic males produce larger amounts of adrenostenone, which often turns women on, somewhat viscerally (subject to genetic factors, and time of the month).
Unfit men produce a greater amount of adrenostenol, which is a social lubricant. It's been shown to be GABA-ergic.
As men age, a greater amount of adrenosterone is produced (elicits respect, gives an aura of responsibility).
Then you have compounds such as DHEA sulphate, a beautifier (inhale it, then look at someone. You are bound to observe some hitherto unrecognized inner beauty radiating from their countenance).
IIRC around eight or nine active neurosteroids have been identified on male skin to date.
AFAIK with females the situation's similar, albeit with certain different neuroactive end metabolites (estratraenol, etc
).Copulins are also referred to as pheromones, though they are structurally different from the neurosteroids. Copulins are fatty acid chains, naturally found in the vagina, synthetically reproduced and topically applied, by both sexes, for different reasons, but chiefly for their testosterone enhancing effects (on men).
There is a growing body of (anecdotal, peer reported) 'evidence' describing various non-sexual effects of certain compounds e.g. pregnenolone, THDOC, cholecalciferol (Vitamin D), proprietory preparations sold by companies like 'Androtics Direct' such as "Instant Shine", and so on. The field here seems wide open - it's like a new frontier, a blank slate for experimentation..
I wouldn't necessarily recommend experimenting with these substances willy-nilly, however. Reports of unwanted effects abound, ranging from a mild 'crash' when the effects wear off, through to full-blown serious illness involving a dna adduct of reagent grade steroid, apparently resulting from chronic exposure to a certain 'pheromone mix'.
Caveat emptor..
