I read a post title with ‘help’ in it signed by moonwhisper and I am in here as fast as a thunder. Unfortunately there’s not to much I can say in concrete response to your question:
a) Natural copulins, as jesse already said, just drive me ‘crazy’. I would love to have more in my life, everyday.
b) Product wise I have been testing Instant Jerk that has some copulins. The product itself brings out a really driven man. A wild stallion.
c) While dancing, (Tango) the ladies and myself seem to respond well to it (sensually) but it is to intense to carry so far. I am still learning how to handle the responses and work with it. Anyhow, I am appreciating every single DIHL from that mix (I am mixing it with MX272).
Now, there is a subtext to your message and that is: how would I feel if I learn that I was “tricked” (my add-on) and my arousal was due to an ‘artificial’ product?
First, try to get Diane’s copulins. Those are natural, organic and Kosher, so if an hypothetical he complains of the fact that you were using something artificial you can reply back saying that it is not, it is natural, organic and kosher… 
Now the root of the question is about the other individual feeling manipulated. I guess it just reminds me of a similar thread a guy post in the ladies room about his GF learning about him using pheros. If I recall well the consensous was that why should she get upset when he is doing the best to provide her with a better ‘pleasurable experience’. The above sounds good and true but I can see how it can be as well a source of conflict and mistrust.
I guess the matter is not about pheromones or not pheromones, to be or not to be, the key is about trust and communication (energy flow) in the here and now with your partner.
Anyhow, I am pondering about it myself as I am so tempted to share some of my pheros with my lady ‘friend’. Indeed, I have even thought about buying her some with my last order, but stopped myself as I didn’t knew how to frame them. How would it look like if I come and say: “Here, I think you should try some ‘Instant Sexiness’? and by the way, yes I am handsome, charming, sexy and caring but as well I was wearing Instant Shine when I met you, MX292 and MX272 as we danced through our encounters and added some TUTH as we ‘consumated’ our passion” Nope, I don’t think it would fly well.
For the moment I have recoiled from the possibility. In any case, she ‘really’ enjoys the effects, loves the smell of ‘lust’ from my neck and chest (she says):o and the other day even hinted if I sprayed something on me as she just goes wild.
I guess that based on her smile, I should understand I am doing a lot of good for her and myself. A pleasurable good.
Sorry for the morning rant, I wanted to be helpful to the moon and whisper some words of wisdom in response to the request. Lacking the concrete one, I just went on sharing a long story. :o
