AVPD does not respond to benzo's and stimulants most likely make SA worse, AVPD relates alot to reward issues while sa is purely caused by anxiety.

Been trying 4FA and it def works for anhedonia wich is not suprising as it releases sero and DA, i think it would work really well for depression and anxiety too for many, it also feels very clean and lacks alot of amphetamine side effects.
Im getting amisulpiride one of the days, it worked for me years ago but after i stopped it and retried it at later points it never worked again so ill see what it does.

Abstract
Dextromethorphan shares pharmacological properties in common with antidepressants and, in particular, ketamine, a drug with demonstrated rapid-acting antidepressant activity. Pharmacodynamic similarities include actions on NMDA, μ opiate, sigma-1, calcium channel, serotonin transporter, and muscarinic sites. Additional unique properties potentially contributory to an antidepressant effect include actions at ß, alpha-2, and serotonin 1b/d receptors. It is therefore, hypothesized that dextromethorphan may have antidepressant efficacy in bipolar, unipolar, major depression, psychotic, and treatment-resistant depressive disorders, and may display rapid-onset of antidepressant response. An antidepressant response may be associated with a positive family history of alcoholism, prediction of ketamine response, increased AMPA-to-NMDA receptor activity ratio, antidepressant properties in animal models of depression, reward system activation, enhanced erythrocyte magnesium concentration, and correlation with frontal μ receptor binding potential. Clinical trials of dextromethorphan in depressive disorders, especially treatment-resistant depression, now seem warranted.

I took 300mg ami today and my behavor got alot more normalised (first tought it was preg etc but i took stims even in recreational doses without them and they didnt make me act manic, stims only did that when i was more shizo and indeed in shizo there's excessive da release with stims thus the weird behavor.
Desoxy releases more da then coke, today ill take high doses of amisulpiride to completely block D2 and D3 and see how that affects the social and anti anhedonic benefits, i suspect it should block any change of more manic behavor compared to baseline.
Also another thing against the da theory, it releases so much da but its barely euphoric.
D1, D4 and D5 agonism should increase wich are involved in the PFC, if the sa and anhedonia benefits remain then that rules out the involvement of D2 and D3 in that.
Illustrates how the D receptors regulate the mu receptors, so if one of the above is the main player modulating mu then ami might even increase euphoria wich would be good as a bit more mood boost would make desoxy nicer.

Abstract
BACKGROUND:
The subjective and reinforcing effects of cocaine in humans are associated with the enhancement of endogenous dopamine function in the mesolimbic system. This study examined the role of dopamine D1-like receptors in the behavioral and mood effects of cocaine by evaluating the effects of the selective D1/D5 antagonist ecopipam (SCH 39166) on subjective responses to intravenous cocaine in 11 subjects with cocaine dependence as defined by DSM-IV.
METHODS:
Subjects were pretreated in a randomized double-blind fashion with either placebo or 10 mg, 25 mg, or 100 mg of ecopipam orally on 4 separate occasions. Two hours later a single intravenous injection of 30 mg of cocaine was administered. Subjective and cardiovascular responses were measured and blood samples for pharmacokinetic evaluation were obtained prior to cocaine dosing and at various times after dosing.
RESULTS:
The euphoric (P = .004) and stimulating (P = .03) effects of cocaine were attenuated in a dose-dependent manner by ecopipam, while ratings of desire to take cocaine were diminished (P = .02). Ecopipam in combination with cocaine was safe and well tolerated.
CONCLUSION:
These data indicate a potentially important role for D1-like receptors in the acute mood-altering and rewarding effects of cocaine in humans."

GABAB, 5HT2A, D1, MU are all closely connected, amisulpride helps anhedonia as the increased da activates D1, this causes downregulation wich is often reported with ami, it upregulates the GHB receptor so if that caused the anhedonia relief it wont make sense.
Opiates dont work in shizo because D1 is hypoactive, stimulants fix this wich is why i need amp before opiates work.
I didnt notice much difference but i take forskolin wich downregulates D1 and the increased cAMP in the pfc may inhibit the pfc benefits i expect, so ill stop forskolin tomorrow.

Retinal dopaminergic receptor affinity and ocular pharmacokinetic profile of piribedil.

Abstract
Binding studies on retinal dopamine receptors have revealed the existence of both D1 and D2 receptors. Human retina micro-autoradiographs confirm the distribution of dopaminergic receptors in the plexiform layers. Piribedil, a dopaminergic agonist, is able to bind to D2 receptors, while its metabolite (S584) preferentially displaces D1-specific radioligands. These results demonstrate that piribedil has a dopamine-like pharmacological profile including direct interaction with receptors. When instilled into the rabbit eye, piribedil penetrates rapidly and accumulates in the pigmented epithelia--the iris ciliary body and chorioretina--before being rapidly cleared. Macro-autoradiographs confirm this distribution and show the levels to be compatible with the affinity of piribedil for retinal dopaminergic receptors."
And indeed i remember it being effective for anhedonia.

I took 20 SC27 capsules and it was simular to a low dose of AMT maybe 4FA a bit, now i take 2 gram of perika a day might raise it as ive read a post about someone in a practice saying up to 5 gram a day is optimal with more people reporting benefits.

OTOH, the successor to SC27 claims to be based on 18g of the original herb http://www.iherb.com...-Softgels/41779

Seems like hyperforin has the anti anhedonic property's and not hypericum.

Saying you have anhedonia because you arent high is complete retardation, with anhedonia social interaction feels like hard work and torture, music sounds like complete shit and every minute is like torture to endure, being bored is a godsend compared to it, as thats just neutral not a unbearable feeling of lack of reward.
http://www.bluelight...rewarding-drugs
explains a bit why some things are rewarding.
Like weed makes me feel like complete shit and makes everything far from fun but eating kebab and lying in bed is the best ever on it, and the worst to do on amp, and opiates ive read dont enhance music and make lying down and not talking the best shit ever (dont like opiates and find them retarded drugs, what good memory's come from that lol

I never ended up trying it, and wanted to get it today but tis discontinued here and pharmacy's need to make it themself but you need a script for that.Did the papaverine do anything for you? Is Nefiracetam still working for you?
Bit unclear about nefi as i have benzo's now in the past i used it instead and prevented or even completely reversed amp induced psychosis in times i was very sensitive and also vefy addicted to amp.

Anyone have any idea how modafinil treats anhedonia
Research found that modafinil elevates histamine levels in the hypothalamus in animals.[44] The locus of the monoamineaction of modafinil was also the target of studies, with effects identified on dopamine in the striatum and, in particular, nucleus accumbens,[45][46] norepinephrine in the hypothalamus andventrolateral preoptic nucleus,[47][48] and serotonin in the amygdala and frontal cortex.[49] Modafinil was screened at a large panel of receptors and transporters in an attempt to elucidate its pharmacology.[50] Of the sites tested, it was found to significantly affect only on the dopamine transporter (DAT), acting as a dopamine reuptake inhibitor (DRI) with an IC50 value of 4 μM.[50]
so, this image may explain some overlaps and factors involved:
