From a vending machine in a pub maybe?
I know this firm - they are well known in the Scottish hospitality industry. They supply machines selling a variety of bin-end sex toys, knobbly condoms, “naughty” novelties eg clockwork willies, edible pants, blow-up sheep etc and performance pills branded under their own range of trading names or will re-brand to whatever company has them in their pubs and clubs.
The business background is wholesale janitorial/cleaning supplies, so not particularly scientific.
I do hope you will find AD a world away from these cowboys! 
For starters, have a good read of this thread, which covers all the basics on choosing and using pheros effectively:
And I agree with the advice above - Ammo and socials is a good way to get started. More overtly sexual pheros like TUTH are good with an established partner but can come-on way too strong for someone you have just met. Although TUTH can be used in the most sexually charged club environments with a bit of social moderation - eg IO or Instant Shine.
