That presented, two conclusions appear to be more important: (1) there are few studies evaluating the mechanisms of toxicity (where, how and if it occurs), which makes the extrapolation of correlations between human exposure and toxicity somehow fragile
Due to the low molecular weight of TB-500, it is extremely mobile
Therefore, in our transcriptomic analysis, special interests were paid to pathways of carbon metabolism, lipid metabolism (glycerophospholipid) and DNA biosynthesis (including cell cycle, DNA replication and purine/pyrimidine metabolism)
We also included hordenine, phenibut, and vinpocetine in the not prohibited group, as they were listed on the USADA website under the category Ingredients that WADA does not prohibit (you will not incur an anti-doping violation for using these ingredients).
