Masteron-P 100 How To Use, Dosage, Results – Who Is The Best Candidate?


Masteron came into being around 1972 by Syntex Pharmaceuticals, the same manufacturing company that brought Anadrol just a few years earlier. The medical purpose of this medicine was to treat or control breast cancer in females using its mild anti-estrogen properties. As the years went on, other manufacturers developed SERM’s like Nolvadex for this purpose since they have reduced and light side effects, and Masteron is not being used much in the medical community.

Although it was around in the golden era, it was never used by bodybuilders. Back in the days before the internet, people were dependent on word of mouth and gurus to guide them forward, so information was extremely outdated. If they would have known this steroid, it was likely to be the #1 steroid to be used. 

Over the years, this steroid gained its popularity and over the past 30 years, it became a major use for the contest preparation cycle to provide bodybuilders with hard muscle on stage.

Benefits of Masteron P

Masteron P can benefit athletes who are looking for strength boosting medicines. This steroid is very beneficial for any athlete who is following a calorie restricted diet in an effort to stay in a specific body weight. The user can enjoy the improvement in strength and stamina, and slight recovery and muscular endurance without any unnecessary weight gain. Masteron P 100 mg has been FDA approved as an anti-estrogen steroid for the treatment of breast cancer.

It is highly recommended to consult a doctor before using Masteron P 100 mg or any other steroid to avoid any health issues in the future.


When Masteron is added to an existing cycle, it will make other steroids more powerful. This steroid can also help reduce some estrogen and progesterone problems. Some people say that stacking Masteron with nandrolone will balance any sexual side effects since those steroids increase Dihydro Nandrolone (DHN) in the body and Drostanolone increases DHT. You can consider it as a great drug to balance hormones.

Just like other steroids, it will work to increase protein synthesis and red blood cell count in the body, but it works slowly. This is the reason why using this medicine won’t show much effects. However, even if you use it alone or stack it with other steroids, it will harden your muscles. Thanks to the way this steroid is structured, it hardens muscles very well. It serves a purpose in competitive sports because you can use it without any worries of increasing your body weight.


The Propionate ester has a short half-life of about 3 days. The longer Enanthate version has a half-life of 10-12 days.

Detection Times

The detection time is listed as 4 weeks for the Propionate ester and 3 months for the Enanthate ester. There have been many fighters and boxers who used it quite often as they can use this steroid without any tension of increasing their body weight. 

What Are The Possible Side Effects Of Masteron P 100 Mg?

Masteron being a mild steroid, it has very low side effects compared to other steroids. However, it is necessary to remember that it still is a very powerful hormone and should be respected. If you over use this steroid at a high dose or use it for a long time, the side effects may increase. These are following side effects of Masteron P 100:

  • Suppression: this medicine will suppress your pituitary glands just like any other exogenous hormone.
  • DHT: Dihydrotestosterone side effects can display themselves by harming your prostate, straining your lipids, and by frying head hair follicles.
  •   Nerve pain and dry joints: although it is not as bad as Winstrol, you can still experience dry joint issues because of Masteron. Other than that, harder muscles can cause pinched muscle which can flare up existing injuries like herniated discs. 

Masteron is not hepatotoxic so iver damage is quite rare. Gynecomastia and high blood pressure are not a major problem. Neither water nor salt retention occurs and the estrogen level remains low while you use Masteron as per the prescription. The main side effects which users find problematic are acne and a possible excessive hair loss. Masteron should not be administered in excessively high dosages. The intake should be limited to a few weeks. Athletes and bodybuilders find this steroid very compatible.

Dosages For Stacking And Bodybuilding

Masteron is one of those steroids that should be stacked with other anabolic steroids to gain the best results. The initial dose recommended to users is300-600 mg per week depending on your goals. If you are using the shorter Propionate ester then inject the steroid every 1-3 days, with the longer Enanthate ester you can inject 1-2X once a week.


Users using this steroid for bodybuilding or for contest preparation purposes love it because they can continue running it up to the day of competition without having to worry about their weight gain or bloating. It is a great cosmetic steroid.

Usage In A Cycle

Using it together with harsher compounds is a great way to ‘add something’ without including estrogenic risks to the cycle. It also binds very well to SHBG so it will improve your cycle overall and make the other steroids work even faster and better.


Models who are trying to look good for shoots or photographs will use the lower end of the dosage range to harden their muscle and to add vascularity.

Female Usage

Masteron is not only our first choice but for female users as well. However, some advanced female bodybuilders have been known to stack it in a cycle at low dosage considering the strong side effects of the steroid.

There are many powerful steroids that cause many severe side effects for female users, but Masteron causes very light side effects which are mentioned above.

Do not use this steroid without consulting a doctor, discuss your medical history and condition with them, then only proceed with using this steroid. Taking this steroid at a high dosage can cause severe side effects.
