What pheromone complements Shine depends on the effect you’re looking for. If you don’t mind me blowing my horn a little, look at my pheromone grid here: Phero color chart by MuskCloud: a visual guide to choosing mixes for a quick visual overview of what pheromones do in combination.
For your second question, Ammunition, or Ammo and Shine together. Some have reported good results with Ammunition and A314 together. It all depends on your unique body chemistry and how the pheromones interact with your body’s natural output.
Good luck and welcome
