Masteron: The Complete Guide

By Mark / 7 months ago

Introduction to Masteron

Masteron is one of the brand names of the anabolic steroid called drostanolone propionate. It is also known as dromostanolone propionate. Other brand names include Drolban and Masteril. Masteron is an AAS or androgen and an anabolic steroid. It is used as medication in some treatments but mostly as a supplement.


History of Masteron

Masteron is an oil based anabolic steroid. It is available as an intramuscular injection, which means it should be injected into a muscle. Drostanolone propionate was first developed and introduced by Syntex in 1970. It was first described eleven years before its development and launch. The drug was marketed as Masteril and Metormon. It was used in therapeutic treatments for over twenty years. The medicine was used in treating breast cancer but that has been discontinued since. Syntex no longer manufactures drostanolone propionate, Masteron, Masteril or Metormon. Masteron is no longer used as a drug. It is available as a bodybuilding supplement or steroid.

Masteron has two forms, Masteron enanthate and Masteron propionate. The anti estrogenic steroid had to be administered frequently and hence the popularity of the intramuscular injection waned. This paved the way for Masteron enanthate, which is a newer alternative of Masteron propionate. Informally known as masto or mast, the chemical structure of the steroid is 2a-methyl-androstan-3-one-17b-ol. The chemical formula is C23H36O3 and its molar mass is 360.53 g/mol. The half life of the steroid is two days and six days for drostanolone propionate and drostanolone enanthate respectively. It is the longer elimination half life that has made Masteron enanthate not only more popular but also more effective.

Masteron is an exotic supplement. It works like other androgenic anabolic steroids but is known to be more resistive of getting converted to estrogen. Aromatization is a common problem with many anabolic and androgen steroids. Masteron can inhibit aromatase enzymes and hence engage with estrogen to effectively block the receptors. Masteron can prevent testosterone from getting converted to estrogen. This increases the availability of free testosterone.

Benefits of Masteron

Masteron boosts the level of free testosterone in the system. This naturally increases available energy. The boost to energy enhances performance. The effect is felt in both strength and endurance. Users can work out harder and for a longer period of time. There is a sustained impact on the growth and development of lean mass. Anyone who has a regular fitness routine will gain lean mass. The steroid can also stimulate appetite to a moderate extent, which also helps in boosting the natural metabolic rate. The steroid is safe and effective if a user follows the recommended instructions, not only in regards to the dosage but also the cycle.

Masteron should be taken as per the requirements of a cycle. It should not be taken randomly. The steroid works best when a user is already into a regular workout routine. This is why bodybuilders and especially power lifters experience the best results. Fitness enthusiasts who go through a bulking phase and initiate a cutting cycle also stand to benefit immensely. The supplement is particularly useful during the cutting phase. It can reduce water retention in tissues and hence prevent or remedy bloating. Many bodybuilders and fitness enthusiasts experience boating, both during the bulking up phase and later through the cutting cycle. The lack of water retention and hence reduced or no bloating helps men to feel tighter and stronger muscles. The pumps are firmer and they muscles have more pronounced contours. Shaping the muscles in their ideal forms is the primary objective of a cutting phase. Masteron can play a vital role in this quest.

Masteron does not facilitate weight gain, even when it contributes to developing lean mass. Lean body mass does not add as much weight as fat and muscle combined. The supplement is not a fat burner per se but its effect on appetite and metabolism can help users shed some of the rigid fat that exercise alone may fail to target. The effect on stubborn fat combined with the enhancement of lean mass, lack of water retention and helping the contours of muscles to be more profound works well during the cutting phase. It is necessary to complete the course of Masteron. There is also a need to embark on a post cycle therapy thereafter to reverse the normal secretions of hormones that get suppressed during the course.

Side Effects of Masteron

There are some side effects of Masteron. The supplement can increase blood pressure, albeit temporarily. Men may experience symptoms of gynecomastia. It is the medical condition of having male boobs. The steroid can also trigger an acne breakout. There is no major effect on psychological health but transient aggression is not uncommon. Some men may have hair loss, especially if they already have a history in their family. All such side effects are usually quite mild and they do not last very long.

The supplement does interact with some medicines, whether prescription drugs or over the counter medication. It is best to consult a doctor if a user is under some strong medication for a serious health ailment. Those who intend to stack Masteron with other supplements should be familiar of the potential combined impact and the possible side effects. Women experience masculinization symptoms. Men may also experience the same but they might not be too perturbed. Women can have excess hair growth on their face and body, their voice may change and changes to sexual desire are common, especially since the sex hormones are affected.

Masteron stacks great with other steroids.

Customer Reviews of Masteron

Masteron is more effective in the cutting cycle. It does not offer much during the bulking phase. Most customers who have used the supplement during the bulk up phase find the lack of water retention in tissues a bit of a concern. Muscles need more fluids when they are being worked on and especially when the objective is to bulk up. The cutting phase becomes much more effective when there is less fluid in the tissues. Masteron does have an effect on physical strength or power. It also has hardens muscles. Masteron can aid weight loss. Many customers have reported losing as much as seven percentage of their body fat during the cutting phase while using the supplement.

Masteron can cause changes to libido. Customers do not experience any particular surge in sex drive because the extra available testosterone is used up during exercise. Those who do not have a fitness routine may experience the effect of enhanced libido. However, those who do not work out every day will not benefit from Masteron in regards to sculpting their physique. The effect this supplement has on defining the torso is only realizable when one works out every day or at least four to five days every week.


Masteron is a safe and effective supplement but it is quite expensive. It should not be used in random. It must be used only in the cutting phase for best results. There should be a post cycle therapy after the course.
