What does it do? Gotta know before my next order.
Well technically as an MX the whole point is to test it and report back what it does. Only the consumer line products are guaranteed.
I assume since you’re asking about it, that you must have read some reports about it to make you consider buying it in the first place. If not, you can do a search, it’s got a ton of reports on it from various users.
Some say it’s a cool guy/most popular guy in school type of vibe, some say it’s a real boyfriend relationship material kind of effect. Other users have reported it’s a little beta or even feminine.
Like I said though, because it’s an MX product, it’s not guaranteed to do anything (although I know AD wouldn’t sell placebo’s) I will say with very few exceptions almost everyone has reported positive effects, and it doesn’t seem to be very None heavy so it’s very work safe.
Testing is fun…and so is this MX. Try it…you’ll like it. 
Go ahead and test it!
Personally I’ve found it to be a little less dominating than a314 yet with all the VIP vibe to it. Your thoughts, opinions and desires all matter just as much, but your demands less so. In exchange, because it’s less powerful (some people can run a mile from a314, especially certain types of girls) it gives me a more approachable and friendly but important vibe.
I find it a very social, charismatic and social anxiety reducing product. MX297 and MX390 - same mix, different scents, are very well worth testing but IME you need to work it hard in a fun/social direction to get best results. Don’t wear it to work unless you are an entertainer or in a line that involves a lot of socialising/chatting-up customers. Go drink, dance and make merry and it will pay dividends for you - esp with friends in an “I’ve never seen you like this before” way.
Someone on here once suggested that if it ever made it to commercial release, it should be named “Instant Rockstar” and I tend to agree fully!
For reception, I would say it is almost the exact opposite of A314 and personally I’ve found that women who responded well to me with A314, tended not to respond well to 297/390, whereas women who were overawed by A314 could respond superbly and lose their nervousness/withdrawal/social anxiety completely. Superb stuff!
Older guys, maybe 30s-up, may find it benefits from a little bit of none but I strongly advise you to give it a good test without adding anything else first as other pheros/mixes can wreck its vibe completely.
Mx297 is a non-sexual social mix. IMHO if I were to classify it I would call it “Instant girlfriend”. It turns a male into a girlfriend. Many posters reported that it was sexual when it was first released because it does promote closeness. But it turns you into a girlfriend.
Women will under no circumstances engage you sexually while wearing MX297. I have 3 to-go’s and I’ll tell you what this does do. It turns you into “Alpha female girlfriend”. Which is not bad. I used this with a girl while testing and I changed my signature the next time I met her to 1 drop A314 and 2 sprays of TUTH. It was a good 1-2 punch. Lead with MX297 and follow up (a day or week later) with TUTH.
Search for the MX297 mix repository.
This is just why I found that adding-in a bit of none when closeness, rapport and escalation had established themselves paid great dividends.
Its what gives Unicorns their wings, the Sun its fire and the Rainbow its spectrum.
Its the cream you find inside oreos and twinkies, and what allows the internal combustion engine to run.
Or rather, its what I recommend sploshing on people when they tell you pheromones don’t work.
Apart from that it makes you the most popular and likable guy in the room.
Its the Nectar of the Gods, only thing you don’t drink it, you wear it.
