Actually i found it in some other steroid forum, just copied from there. I only found later the original area1255 source.
Telephone, then. I believe ya!
This comes from a certainly interesting, kinda weird, schizoid-looking blogspot source, "
Area-1255; a blog tackling the latest issues in the Internet 'Underground', we also write & publish guides on Computer Security topics, and we have a few different contributors who post some of their favorite achievements. Enjoy."
And it's got some strange shit... This article itself is totally disorganized and rife with conjecture rather than logic. It actually strongly reminds me of something from a guy who posts here regularly.
But I can do something with some of the references, e.g. this is interesting:
Foradori, C. D., Werner, S. B., Sandau, U. S., Clapp, T. R., & Handa, R. J. (2007). Activation of the androgen receptor alters the intracellular calcium response to glutamate in primary hippocampal neurons and modulates sarco/endoplasmic reticulum calcium ATPase 2 transcription. Neuroscience, 149(1), 155–164. doi:10.1016/j.neuroscience.2007.06.054
But not with respect to cognitive effects, but rather potentially to motoneurons (i.e., strength; cortical excitability, etc.)
