Thank you all for your input, it is appreciated a lot.
One clarification and one more question, please.
I know you need a choline source to run with the racetams, does centro provide an adequate enough source?
Also - what is the more potent for 'anti-aging' - deprynl, idebenone, centro, others?? From what I have read, deprenyl seems to be the one:
(James South MA)
4 series of rat experiments, as well as an experiment with beagle dogs, have shown that deprenyl can extend lifespan significantly, even beyond the “technical lifespan” of a species. Knoll reported that 132 Wistar-Logan rats were treated from the end of their second year of life with either saline injections or 0.25 mg/kg deprenyl injection 3 times weekly until death. (11)
In the saline-treated group the oldest rat reached 164 weeks of age, and the average lifespan of the group was 147 weeks. In the deprenyl group, the average lifespan was 192 weeks, with the shortest-living rat dying at 171 weeks, and the longest-lived rat reaching 226 weeks.
In a second series of experiments Knoll treated a group of 94 “low-performing” (LP) sexually inactive male rats with either saline or deprenyl injections (0.25 mg/kg) from their eighth month of life until death. (11) Knoll had already established a general correlation between sexual activity status and longevity in the rats. The saline-treated LP rats lived an average 135 weeks, while the deprenyl-treated LP rats averaged 153 weeks of life. The saline treated HP rats lived an average 151 weeks of life, while the deprenyl -treated HP rats averaged 185 weeks of life, with 17/50 HP-deprenyl rats exceeding their estimated technical lifespan of 182 weeks. (20)
Knoll’s experiments were partially replicated by Milgram and co-workers and Kitani and colleagues. (11) Milgram’s group used shorter-living Fischer 344 rats, while still starting deprenyl treatment at 2 years of age - in effect later in their lives - and found a marginally significant 16% lifespan extension. The Kitani group, also using the shorter-lived Fischer rats, started their deprenyl treatment at 1.5 years of age, and found a 34% life increase. (11)

Thanks.
