Hello ahyour!
Welcome to PheromoneTalk!
I think you should consider mobocaster’s take, specially the one relating your age to the correct dosage of mones applications.
Another thing, since most of the reported self-effects of AMMO is a boost in confidence, and you are not looking for it while using AMMO (plus the fact that you have tasted a314’s confidence boosting self-effects), AMMO self effects might be subtler for you to feel/recognize. Thus, upping AMMO dosage is indeed a good option.
Regarding TUTH, the best scenario to use it solo is when you are alone with a girl who is willing to have sex with you (wife, girlfriend, or any girl whose willing to drop their panties off to welcome you), otherwise, expect no hits.
Thus, when going to bar, its either best to start off with AMMO (at your sweetspot application) alone, and as you engage your target and she responds on sexual innuendos, then you’ll start to use the TUTH. AT your age, you need to at least start with the 2x strength of TUTH. And if your target are older ladies (at your age level) you need to up TUTH dosage applications. Less TUTH if your targets are young ladies.
Now, since you are a mature man, why don’t you try using A314 as the base? Pair it with TUTH and you’ll feel the difference. 
You can try MX297 with TUTH too at the bar, or IShine+TUTH. Don’t worry if you don’t have the MX297 and IShine. I just dropped your $25 Intro GC to help you make that second order containing these mones.
Check your inbox and spam folders to retrieve and use the GC.
Happy pheroing!
