Chlorodehydromethyltestosterone.

Turinabol is a quite weak oral AAS, the weakest I have ever used. It comes in 5mg tabs and you have to use a lot of it in order to attain results. It is not a DHT, so aromatization is an issue. It can be used to kick-start a cycle for a couple of weeks and it is definitely not my favorite oral AAS by any means. If I were to add oral AAS to my bulking or cutting cycles, would go with either Anadrol or Anavar, depending on my goal.

It is probably more potent than Anavar.
Though it is not DHT derived, it cannot aromatise or convert to DHT due to the 4-chloro alteration.

It is probably more potent than Anavar. When I compare the two on a mg basis, Anavar certainly did it more for me. Maybe it was because the TBOL I purchased was either under-dosed or just low quality stuff, I never cycled TBOL after my first experience with this compound.
Though it is not DHT derived, it cannot aromatise or convert to DHT due to the 4-chloro alteration.I was taking 0.25mg Arimidex EOD while cycling TBOL since my cycle consisted of also Test and Deca, but it is of course good to know that TBOL doesn't aromatize although it is not a DHT derivative.

Yep, doesn't aromatize, so any any estrogenic effects would have been due to the test and/or Nandrolone. Tbol is simply a structurally altered form of testosterone or a testosterone derived steroid. It doesn't aromatize due to the added chlora group. This same added chlora group is also what makes it non-androgenic. Anyway, there you go. That's why it doesn't aromatize, and now you know why. Hope that helps
