Mibolerone (also known as Cheque Drops, Matenon, dimethylnandrolone and dimethylnortestosterone) is an orally active AAS derived from Nandrolone (19-Nortestosterone). Structurally, we could basically say that Mibolerone is Oral Trestolone (MENT).
It was originally developed in the 60s for veterinary use. It was specifically intended as a form of birth control for female dogs, but it found its way into the enhanced community (who else would pop canine birth control pills? :)).
There is very little preclinical or anecdotal information about the effects of this drug (and obviously 0 clinical info), but what’s known about it is that it’s one of the most powerul oral anabolic androgenic steroids ever developed.
It’s also known for causing serious roid rage and an increase in explosive strength, which is why it’s more commonly used in combat sports and powerlifting than in bodybuilding (even though it builds a ton of muscle mass).
In terms of side-effects, you can expect it to destroy your liver (it’s 17alpha-alkylated) and your lipid panel. Being a derivative of Nandrolone, it will also cause progestogenic and estrogenic side-effects like water retention and gyno (so using something like Caber or Prami & Arimidex or Aromasin would be necessary to prevent those sides).
The increase in water retention will lubricate your joints, but it will make you puffy and it will increase your blood pressure significantly, which is not only bad for your heart but also for your kidneys.
I wish I could tell you whether it has androgenic side-effects or not, but I have never been able to find reliable information about its effects on hair loss and sebum production. It’s fair to assume that it can cause both side-effects.
What I can tell you for sure is that, like all Nandrolone derivatives, it will cause a serious degree of Testosterone suppression that will last for months after discontinuation (the metabolites of Nandrolone and its derivatives tend to stay in the system for months on end).
Given the lack of reliable anecdotal information about this drug, I am unable to recommend a solid protocol. I have seen people recommend up to 10mg/day for 4 weeks, but with such a rare and potentially dangerous drug I would recommend one to start with a lower dose (keep in mind that this drug tends to be used pre-fight or pre-contest and very sparingly).
I would discourage most people from using this AAS. It’s hard to find, and its extreme nature only makes it suitable for use by experienced enhanced athletes who have a good understanding of the risks that come with it. I would most definitely never recommend someone to do a PCT after blasting this AAS. If you want to take Mibolerone, be ready to cruise on Testosterone for the foreseeable future.
