You should all have several concerns about PLR 8-53:
1) There has only been ONE peer-reviewed study that included human trials ever published on this pharmacological agent. (
https://www.ncbi.nlm...v/pubmed/418433)There is not nearly enough research on this compound to consider it safe for consumption. No one has studied the long-term effects of the use of this drug in any capacity.
1a) Of the 19 studies referenced in "PRL-8-53 Enhanced Learning and Subsequent Retention in Humans as a Result of Low Oral Doses of New Psychotropic Agent", Hansl cites himself 4 times. In other words, 21% of his references are to himself. This is generally considered a poor practice.
1b) The study is from BEFORE 1975 -- <<38 YEARS OLD>>. Technology and our understanding of neuroscience, pharmacology, and molecular physiology has changed markedly since then.
1c) The note at the end of the study that reads: "Following completion of this study it was found that the particular lot of PRL-8-53 that had been used contained a small amount of the desmethyl compound as admixture, which may also have contributed to the observed effects." This is further cause for concern because it is a testament to the low quality and poor consistency of the product that had been used in the study.
1d) No further studies were ever conducted despite the "positive" results of the above reference. Why not? Did the researchers run out of funding because of flaws in the product? Were there negative effects reported months or years after the study had been published? Additionally, no followup studies were conducted with the subjects that participated in the 1978 study.
1e) The study only administered a single FIXED dose (5 mg) for all subjects, regardless of mass, and did NOT consider the effects of higher doses.
1f) The study did NOT consider contraindications with other medications. Drug-drug interactions can severely impact the physiological effects of medication.
2) The researchers [Nikolaus R. Hansel (Ph.D.) and Beverley T. Mead, (M.D.)] who synthesized this compound and studied it's effects are both DECEASED. They cannot be contacted for further insight or research developments on this drug.
3) Dr. Beverley T. Mead voluntarily surrendered her medical license in 2002, approximately 7 years before her death IN LIEU OF DISCIPLINARY ACTION. (

4) What are the credentials of the individuals synthesizing this compound for the group-buy? What level of standards is their laboratory held to? Who monitors the laboratory and holds them accountable for violations of regulations? Are they a reputable source that acquires their reagents from other reputable sources?
5) Who will test this compound to ensure that it is >99% purity?
There are too many unknowns here for consumption of "PRL-8-53" to be even remotely safe. No one can guarantee that you will even be consuming that compound if issues 4) and 5) are not addressed properly. It is greatly concerning that this a questionable study to begin with, and that there is virtually ZERO additional research to support the results of the aforementioned study.
