As Taggle pointed out, the Togo’s are good to try out the mones, though the best bang for the buck is the 30ml bottles.
Ok… This is what I see at the Androtics store for IS/b:
“Instant Sexiness B” for Women - TO GO! :: Pheromones To Go ™ (Portable / Travel Size) :: Androtics Direct (Kitten – Original Androtics Formula For Women - Alpha A314)
For the Instant Shine
“Instant Shine” Feel Good Pheromone - TO GO! :: Pheromones To Go ™ (Portable / Travel Size) :: Androtics Direct (Instant Shine Spray — Mood Enhancing Pheromone For Men - Alpha A314)
For the Instant Shine, just give the 1x strength a go… the 2x strength equals to 2 sprays of the 1x…
Are you comparing the IS/b with Scent of Eros? They are different products, though, I’d suggest you pickup the Togo of IS/b and compare them both on yourself… others that have experience with Scent of Eros might be by and chime in…
I see that you’ve been looking through the Stickies as you posted on one of Tisha’s. That’s great! We’ll get you going soon enough, Pika!!
