I think it is all too easy to jump on the lets kill big pharma and amphetamine don't work.
I feel like, while racetams are a wonderful class of drugs, in a nootropics board the opinion of them could hyperpolerize just as a group of doctors might hyperpolerize in their beliefs about amphetamines.
I do take amphetamines and racetams so take anything I say with a grain of salt since their is inherit unintentional bias and cognitive dissonance in anything I say of these substances.
These are the statements I can gather from the previous posts
1. Racetams make amphetamine stronger.
-IMO, I affirm this.
"PIR given alone caused no significant changes in mouse locomotor/exploratory behaviour, whereas the same dose combined with either MET or MDMA significantly enhanced their stimulatory effects. Different possible neurobiological mechanism underlying drug-drug interaction of PIR with MET or MDMA are discussed, as modulation of dopaminergic, glutamatergic or cholinergic brain systems. However, the interaction with membrane phospholipids seems as the most plausible mechanism explaining PIR action on activities of neurotransmitter systems. Despite that our behavioural experiment cannot serve for explanation of the pharmacological mechanisms of these functional interactions, it shows that PIR effects can increase behavioural stimulation of amphetamine drugs. Thus, the reported combining of PIR with MET or MDMA by human abusers is not perhaps a coincidental phenomenon and may be based on existing PIR potential to intensify acute psychostimulant effects of these drugs of abuse."

2. Amphetamines seem to increase male temperament subjectively according to one persons claim.
-IMO, I affirm.
2a. Increasing sex drive
-amphetamine and methylphenidate can increase sexual desire by increasing dopamine release. [

2b. Increasing extraversion
-"Decreased LI has been associated with dopaminergic agonist intoxication and schizophrenic conditions. We previously demonstrated reductions in LI among individuals characterized by higher levels of trait Openness and Extraversion. This study replicates our previous findings, " [

2c. Increasing confidence
-'The failure of either D or D + A to affect risk-taking seems to contradict
previous findings. One potential explanation is suggested by Hurst's findings
(in press) that amphetamine-induced optimism about performance outcomes
may depend upon ego involvement in the task being performed.' [

2d. increasing goal oriented behavior
-These findings indicate that amphetamine sensitization leads to a rapid progression from goal-directed to habit-based responding but does not affect the performance of established goal-directed actions. [

3. Feelings of ear pressure could result from high blood pressure as a result of either a racetam or amphetamine or both.
-Probable reports on longecity, twitter, reddit, writestudio, seacoast, and friendfeed for Racetams
-Even more probable for adderall many anecdotal reports.
4. Amphetamine has diminishing returns.
Assuming the purpose is for cognitive enhancement and not a high I deny this statement.
-Development of sensitization to amphetamine may depend on the daily dosage of amphetamine. ["Individual differences in amphetamine sensitization: dose-dependent effects"]
-n humans, however, there is no systematic evidence of the development of behavioral sensitization to amphetamine after acute or chronic amphetamine treatment when the drug is used in the therapeutic dose range (i.e., is not abused). [ "Clinical psychopharmacology of AD/HD: implications for animal models"]
-The absence of observed sensitization development in humans (compared to that observed in rodents) may be explained by different amphetamine metabolism or different mechanisms of action of amphetamine in humans versus rats.[ "Update on amphetamine neurotoxicity and its relevance to the treatment of ADHD"]
-The use of the newer stimulant agents shows a safety profile of frequent, but usually mild side effects. They are generally safe in special populations. The risk of developing long-term substance abuse with attention deficit hyperactivity disorder, without co-morbidities, is small and may decrease with proper treatment. [

5. In the long run, Amphetamine is horrible for your brain.
At clinically relevant doses deny.
-In summary, this study demonstrated that at high doses, m-AMPH, increased stereotyped (sniffing) behavior in rats, but d-AMPH did not. However, this study shows that d-AMPH and m-AMPH seem to have similar effects on the brains energetic metabolism. [
http://www.ncbi.nlm....ubmed/23022501] While this sounds really bad, I find three issues with how people apply this and similar findings 1. Rats seems to have a different metabolism of amphetamine 2. This is with HIGH doses that are INJECTED. How the brain changes to chronic dosing does not mean a fraction of that dose will cause the same changes. 3. Not all of the amphetamines are the same so methamphetamine findings may not represent accurately dexamphetamine. And, that while high doses of d-amphetamine may effect brains energetic metabolism this is in 1. rats who metabolize amphetamine differently 2. injected 3. at chronic dosing 4.this effect is not generalized to the entire brain and rather seemingly localized.
6. Strong evidence exsists that amphetamines are counter-productive in terms of nootropic value if continued for an extended period of time.
At therapeutic doses I must deny this statement
- Results suggest part of the beneficial effects of therapeutic doses of d-amphetamine for ADHD could be via increased hippocampal neurogenesis. [Chronic D-amphetamine administered from childhood to adulthood dose-dependently increases the survival of new neurons in the hippocampus of male C57BL/6J mice.]
-In children with ADHD, once-daily 10 mg-30 mg MAS XR was well tolerated and significant behavioral improvements were consistently maintained during 24 months of treatment. [

7. Racetams are way superior to classic stimulants. With, one report emphasizing noopept.
I have to deny this statement also
Since the mechanism of amphetamines and racetams are independent of each other I feel that it is inappropriate to regard one as superior to another when they do distinctly different things in the brain.
to compare things like NDMA and AMPA modulation and increased cellular fluidity to Dopamine and Noreprine reuptake inhibition by binding as a ligand does both of these substances a injustice and greater confusion over stacking in the hopes of "synergy". They are independent of each other the only reason we can compare them is because the brain is very complex and has many systems that result in the "same" subjective affect. racetams are like amphetamines because they both may have the ability to improve cognition. However, racetams are not equal to amphetamines because of totally distinct mechanisms of actions. Cognitive enhancement is our dependant variable. However, racetams and amphetamines are nearly independent of each other and distinct independent variables. So, rather than which is better it should be these are different tools that do similar things and id rather have a tool box filled with all kinds of skrewdrivers rather than just a philip's head. - If you aren't trying to do much maybe you might be able to get by on just philip's head.
