Nice order you made there. Not sure why you bought TAC though. That one is kinda advanced.
Start with one product at a time. Use one spray at first and work your dosage up till you find a amount that works well for you.
Tuth and ammo should come in around 1 to 3 sprays
TUTH and Ammo tend to work best on the upper chest and IH works good to the neck, back of neck or hair.
You need to experiment a little because we are all different and use different dosages and have different application points though.
