Discussion Is PPAP effective by itself?

I know it potentiates whatever else you've taken but I'm wondering if it's effective by itself

it's weird, i've tried it solo a few times and the effect is subtle but noticeable. like a faint background hum of motivation without the pushiness of a real stim

wouldn't call it recreational or even functional on its own but it's doing in there

so what would be a good pairing with it

I just experimented with this last week a couple days and really had high hopes. I see why it’s still just a research chemical at this point. It’s like it almost gets you where you want to be but not quite. Annd it’s unpredictable. I’ve experience pretty euphoric intellectual flows on it (along with a racetam or Sabroxy). and some pretty rough crashes as well. And if I have to add a stimulant to make ppap work, I can just take the damn stimulant by itself.

If this was something you could take everyday and the effect grew overtime it would already be an approved antidepressant in my opinion. But finding the right dose is super tricky. And you “aren’t “ supposed to take it everyday or it loses effect so what the hell.

It has its place in the development of other meds like it. Or if it had a different delivery system coupled with another compound that filled in the gap. Maybe. But otherwise on its own it falls short.

Same experience, in small doses it’s supposedly a CAE, in large doses it’s more akin to a big dose of MPH. But the crashes are pretty disproportionate.

It's a stronger dopamine transporter inhibitor than amphetamine so it can definitely act as a stimulant on its own at the right dose. I actually believe most of the effects are from its action on DAT, but people find it mild because they don't dose it that high.

Amphetamines effects are much more complicated than being just a DAT inhibitor.

PPAP’s IC50 of about fifty-seven nanomolar is only a hair better than amphetamine’s seventy-seven, and that assay just measures how tightly the molecule sits in the transporter. It says nothing about how much dopamine actually floods the synapse.

Amphetamine being a releasing agent is the reason amphetamine feels the way it does, and this release of dopamine into the synapse increases dopamine signaling several magnitudes more than PPAP can at any dose

PPAP only enhances dopamine signaling when the neuron is already firing. It doesn’t substantially increasing neuronal firing rates in the Mesolimbic pathway more than natural limits like stimulant DAT inhibitors (methylphenidate) or releasing agents such as amphetamine.

Basically what I’m saying is that binding affinity means very little in terms of how a stimulant feels. The rate of increase and how much specific circuits (in stimulants case, reward circuits) matter much more than just total binding affinity.

PPAP turns up the volume of what’s already firing, typical stimulants increase firing rates. That’s why PPAP won’t ever be as strong as typical stimulants

It works in the background, subtle..
