You can wear the mones wherever you want:
I mainly use neck,throat,behind the ears,back of neck, forearms and wrists depending and the none mainly goes on near the centre eg each side of neck/throat whilst the socials/status start from the forearms/wrists and work-in. This does seem to key-in better with my natural sig, promote the right diffusion and follow the desired pattern of interaction - ie the strongest none effect is when someone is cuddled into me.
IG - I’d say it is far better for someone your age and its the A314 that can get taken as older, stuffy, standoffish and remote - esp by younger women.
IO - There are shortages of certain molecules. AD has hiked the price and restricted sale pro-tem. I hope it changes.
Storage. Mones are very very resilient, so temperature is seldom an issue. Certainly putting them in your pocket won’t matter. Even gloveboxes on scorching summer days are no great bother - although some scent components may suffer. more important you keep them dark. Literally hundreds of threads on this, so whoever was on about a “certain temp” is talking out their arse!
