It reads as if something's missing probably because something is. The citation! Which is Gupta, V., Bhasin, S., Guo, W., Singh, R., Miki, R., Chauhan, P., … Jasuja, R. (2008). Effects of dihydrotestosterone on differentiation and proliferation of human mesenchymal stem cells and preadipocytes. Molecular and Cellular Endocrinology, 296(1-2), 32–40. doi:10.1016/j.mce.2008.08.019Great read and awesome content. In the section in tren you state
"It decreases fat mass and increases skeletal muscle mass by acting analogously to
DHT"
So it acts similar to DHT despite being a 19 nor and not DHT derivative. Could you explain a little more about this, or maybe I am not understanding correctly?
That section is informally written so I didn't put in the references or footnotes, but am always happy to give those, and to provide evidence about any factual statements. Basically, DHT – a potent androgen, like Tren; but shitty anabolic unlike Tren – reduces fat mass by "committing preadipocytes to a myogenic rather than adipogenic lineage," i.e., at the pre-translational level Tren, like DHT, tends to build muscle rather than fat with energy – as well as by increased lipolysis, and reduced lipid accumulation.
The "DHT-19-Nor-Test" model is broscience, btw. I've written about this briefly here: [link]
It's a bodybuilding hypothesis, not a scientific framework. It comes from an infographic someone came up with years back. I won't attach it because it'll just contribute to further repetition of errata.
