I have like 12 different to go for Full bottles now, lol. However, I use it only two times per week. I am also thinking about ordering A314. I don’t think I will finish all this for 2 or 3 years 
Can it last and be effective for two years?
If I understand you correctly you have 12 different To Go bottles that are basically full. If you store the pheros in a cool dry place they will last a long time.
But trust me - once you get into testing them they won’t last that long … lol.
And really - the To Go bottle sizes are just enough - usually - for most people to use and figure out that the products work. They have enough for you to try varying doses and figure out where your sweet spot is. If you are going to spread their use out over a long period of time either you will have blazing obvious successes the first time you use these products or you might never see their effects.
I would really recommend taking a more intentional approach of testing - Renny’s Newbie Tricks thread in my signature block gives you a good idea of how to do good testing.
Good luck!
The shelf life of our products is about 3 years longer if you take care of your pheromones as bossy says.
12 5ml bottles is actually nothing to go through when you get going. I remembered 2 months ago I went into my pheromone bag and most of my social bottles and those were 30ml bottles were all empty and I ordered them this year. 
Yea I agree… I think you’ll find that the to-go bottles go a lot faster than you think also you only use them twice a week? I hardly ever leave home without wearing something
Well, the reason I don’t wear mones too frequently is that I am a part of very prestigious profession, and I have a lot of work that needs to get done daily. I realize that I get fatigue quicker when I wear them. Except TUTH, my body chem seems to react pretty well to most pheremones. For TUTH, I think I need to add either IS or IO.
