Need some advice on a new order!!!

Hi everyone !!! Looking on placing new order and need some advice!! I currently own this products , IS,IO,IH,AMMO,TUTH,A314 ,in a togo .Also P75 3oml bottles at 2.5 mcg per spray as well as Summer ammo 30 ml bottle.
With this order I was thinking on getting MX297, P74,P83,P91 and P102..
After reading up on forum it seems that ideal msg for P91 is 2.5-5.0 per spray , but they only sell it at 12.5 and higher per spray . Any suggestions ???/
Also it seems that P74 ,P83 is most effective at 10-20 mcgs per spray.. I know for everyone its different, I’m just debating between getting 30 ml bottle at 5 mcg or 10 mcg. Any suggestions ??? As well as if you think that I should try some other Putatives and add them to the order , I would be highly grateful for your suggestions!!!
