At its simplest, Halodrol is a type of 17aa steroid that is derived from testosterone. Akin to its counterparts, this prohormone has the ability to promote key changes in the body that are extremely beneficial in terms of building size and mass as well as enhancing muscle endurance and accelerating your overall recovery time after going through a punishing workout.

The technical name of Halodrol is Chlorodehydromethylandrostenediol-CDMA (4-chloro-17a-methyl-androst-1,4-diene-3b,17b-diol) and also known as HD and H-Drol among bodybuilders and weightlifting buffs. The chemical structure of this prohormone closely resembles that of Turinabol (Chlorodehydromethyltestosterone), which is a modified version of the anabolic steroid Dianabol or “D-bol.” The chemical formula of Halodrol is C20H29C1O2 and has a half-life of approximately 16 hours.

The chemical structure of Halodrol

This prohormone basically works by getting into the bloodstream and sticking to the walls of the muscle cells. This activates a reaction with the nucleus that promotes an increase in its overall production of protein while boosting its synthesis of the same in the process. This increase in protein production and synthesis leads to a buildup of muscle tissue that will eventually become muscle gains.

Halodrol has become quite popular as the prohormone to zero in on when it comes to achieving the most ideal set of abs. Based on numerous logs and testimonials from users, they’ve been able to get flatter yet more muscular abdominal muscles when they cycled with this steroid. They also emphasized that Halodrol helped them perk up their vascularity and realize high-quality dry gains with only very minimal to no water retention.


Based on the feedback of Halodrol users, this prohormone can help stimulate the following bodybuilding benefits:

  • Improves vascularity

  • Boosts overall muscle size and strength

  • Helps enhance pumps

  • Promotes fat loss while preventing catabolism

  • Cuts down recovery time

Note; dosage information is only for scientific reference purposes. SARMs Central, does not condone the human consumption or use of this substance outside of a controlled scientific environment (i.e. a lab).

It is highly recommended that you start with a daily dose of 50mg to gauge your tolerance to this prohormone. You can bump up your dosage to 75mg in 3 to 4 days’ time if you’re not feeling any adverse reactions. User logs in bodybuilding forums report that 125mg daily dose is possible, but should be reserved for seasoned users. Now while Halodrol can give you an “alpha male” feeling almost immediately, visual results can take up to 2 weeks.

A typical Halodrol cycle runs for 5 to 6 weeks, whether you’re using it as a standalone prohormone or stacking it with other anabolic steroids. However, it is very important that you stack it with non-methylated substances or else you can be highly vulnerable to liver health issues. Given its rather long half-life, using Halodrol is as simple as taking one dose in the morning and another in the late afternoon or evening.

Keeping in mind to have an on-cycle support when using Halodrol is also essential to stave off potential liver toxicity and cardiovascular problems sooner or later.

Potential Side Effects

Now while we’ve emphasized earlier that Halodrol does not aromatize when cycled, it can still cause the side effects below when not properly used:

  • Can cause temporary shrinkage of the testicles

  • Can promote bouts of acne and oily skin

  • Can stimulate hair loss in men predisposed to baldness
