1 - depends a lot on your work environment. Typically an Androsterone/status product like IG (younger) or A314 (older) but in some situations where socialising/entertaining/ interaction is the key, a highly social/engaging product like MX297 might be the thing.
2 - Socials eg IO, IH or Instant Shine are all good starters, plus Ammo, which is a balanced social/sexy/status mix that is very widely usable.
3 - see above/ Younger women generally go on social-heavy or more balanced mixes, esp in more sedate environments like church. Too heavy or too much sexual and you can appear creepy/aggressive or off-putting. However, as you move into more uninhibited environments, you will likely find that a more robust sexual will become more tasty. You can find exceptions at any age though.
4 - Debatable but mones like Androstenone can help put you in a better frame of mind to work out hard.
5 - there is a strong element of finding what works best for you and at what dose. Age is an important factor here, especially where Androstenone products are concerned. Once you have found your doses for a range of products used standalone, you will be in a much better position to mix within your limits - and know when you can push them. Broadly, avoid mixing similar products as they can push you into OD, or drive other products so far back in the mix that they become useless. The only actively bad mixes I’ve found are Alphanol/IO or MX297 with A314 - not exactly bad, more they invariably confuse or cancel each other. P79 is another you need to be careful with as it can amplify any bad aspects of a mix just as well as the good.
6 - Yes, they can stink to high-heaven, esp on natural fibers which pheros can bind to strongly and it can takes weeks to get the smell out. Temp is an important factor as well as sweat - which can re-activate the smell even if you think its washed out. Spraying on or under fabric also reduces diffusion considerably and limits effective diffusion to very hot environments where body heat isn’t needed. A tight t-shirt on a young guy in a club might be the classic application.
It can take a while to start smelling but back when I started, I went through quite a few good shirts before I realised that Pheros are best used and most easily washed on skin. You also tend to need a considerably higher dose to be effective on clothes and that soon gets expensive!
Similarly, you don’t want to be spraying anything with Androstenone on hair, pits or “down there” as it can get very smelly, surprisingly fast and it takes a long hot, hard scrub or even a shave to shift it - Ow!
A little TUTH just below the belly button can work wonders with blowjobs but that’s a less hairy/sweaty area, so easier to clean - and I would save applying it till you are pretty certain she’s DTF, so you don’t have a “What died down there?” moment!
