I recently purchased and tested a popular brand of "17b-Methoxytrienosterone" because I have received many inquiries as to what it might actually be. I took the contents of 10 randomly selected caps from the bottle and did a rapid extraction with ~10ml of cold methanol. I then filtered the solvent through a 0.2mic PTFE Whatman syringe filter and evaporated the extract over extremely low heat in the absence of light. The yield was a distinctly yellow, apparently pure crystalline solid. By USP 197<K> analysis method, I prepared a KBr pellet with some of the material and performed an infrared scan (reference attachment.)
It would appear that this compound is indeed a ketone but also appears to possess at least 1 hydroxyl function (with some possible cellulose contamination from the many shoulders in that region.) The presence of a methoxy function is inconclusive. The alkene stretch is significant, maybe not enough so to be a triene, nevertheless it could be. It is certainly a typical steroidal hydrocarbon but without further analysis, I can not say for certain. I would need to test additional brands, do some UV quantitative analysis and test the cousin product called 'TRN' also to get a better understanding of what this truly is. A GC/MS analysis could also provide some additional insights, so sorry guys, this is all I can do for now. All I can say is that it's not what I would expect 17b-Methoxytrienosterone to look like, but I can't rule it out either. Therefore, I have no solid conclusion as to it's identity at this point.
