MENT / Trestolone – Mystery Monster Steroid – Doctor's Analysis

MENT or Trestolone is a 19-nor nandrolone-derived steroid, 7α-methyl-19-nortestosterone. It was investigated as a potential male contraceptive and replacement for TRT but abandoned, likely due to estrogenic side effects. There is a lot that remains mysterious about this drug: it seems to cause hair loss despite not generating DHT metabolites, and there are paradoxical dramatic estrogenic side effects clinically despite low estrogenic activity on paper. The gray-market legal status, the limited data from studies, and the wildly varying dosages raise more questions. In some cases men are using doses over 50 times what was tested in clinical trials – it’s no surprise we see major side effects! In this video I take a look at what we know about MENT as well as what’s still unclear.

As the Anabolic Doc, since 2003, I’ve provided men who are using or have used anabolic steroids a confidential, ethical and professional medical venue to discuss their use. I do NOT in any way support the use of any performance enhancing drugs – PEDs, anabolic steroid or other medicine for muscle building or body transformation. The “off-label” use of PEDs, as such agents is considered elicit and may lead to adverse health outcomes. Please consult an expert health professional regarding any medical agent and do NOT use any medicine without the explicit advice and supervision of an appropriate medical expert.
