Masteron | Steroid Review

Masteron contains the active steroid drostanolone. It is an effective anabolic-androgenic steroid with a versatile role as an enhanced performance drug. Despite its potent effects, Masteron is somewhat misunderstood in the general and bodybuilding community. Here, we shed light on its traits and clinical effects.

Masteron was developed in the 1960s as a treatment for breast cancer and was quite effective until it was replaced by non-steroidal drugs such as Nolvadex and Arimidex, which avoid the androgenic (virilization) side effects of Masteron.

Chemical Structure | Clinical Traits and Benefits

The active ingredient in Masteron is Drostanolone, a derivative of Dihydrotestosterone (DHT) with an added 2a-methyl group. DHT is a potent androgenic descendant of testosterone, meaning it has a high affinity for the androgen receptor and cannot be converted to estrogen (female hormone). Dehydrotestosterone (DHT) is subject to degradation in muscle tissue by an enzyme called 3α-hydroxysteroid dehydrogenase (3α-HSD), thus DHT shows very low anabolic effects (muscle-building effects). However, Masteron is a poor substrate for 3α-HSD, hence it retains high anabolic activity on muscle and bone. In reality, taking Masteron by itself will result in limited muscle gains, much less prominent than testosterone.

Masteron is a valuable addition to any other anabolic steroid due to its significant ability to enhance the effectiveness of other steroids. This trait is coupled with its low toxicity. We'll delve a bit deeper into its interesting synergistic effect with other steroids.

Drostanolone, like DHT, has a high affinity for sex hormone-binding globulin (SHBG), a protein that binds to testosterone and other steroids, rendering them inactive. Only about 2% of circulating steroids are in their active form, while 98% are inactivated by SHBG. Drostanolone’s higher affinity for SHBG means it competes effectively, allowing a higher percentage of other steroids to remain active in the plasma, thus enhancing their impact on target tissues.

Proviron vs Masteron | Masteron vs Primobolan

Both Proviron and Masteron are direct derivatives of DHT with similar chemical structures. Both show high affinity to SHBG, with Proviron having a slightly higher potency in this regard. However, Proviron has negligible muscle-building effects as it is subject to degradation by 3α-HSD. In contrast, Masteron exhibits real anabolic impact because it is resistant to this process.

Masteron's muscle-building effects can be compared to those of Primobolan. Empirical data suggests that while Masteron is effective, it is slightly less beneficial for muscle mass gains compared to Primobolan.

Key Points:

  • Proviron vs Masteron: Both are DHT derivatives with high SHBG affinity, but Proviron has minimal muscle-building effects due to 3α-HSD degradation.
  • Masteron vs Primobolan: Masteron shows anabolic effects resistant to 3α-HSD degradation, comparable to Primobolan, though slightly less effective for muscle mass gains.

Half-Life of Masteron

Masteron Propionate has a half life of approximately 2-3 days, requiring more frequent injections (every other day). It may be combined with any steroid, both oral or injection, but it's especially suited to serve with fast-acting steroids such as testosterone propionate and trenbolone acetate.

Side Effects

Potential side effects of Masteron include hair loss and acne due to its androgenic properties. Despite some myths, it has very low impact on the brain and poses very low risk in terms of behavioral or mood changes. Masteron does not aromatize to estrogen, hence posses zero risks of water retention and gynecomastia. As already stated, Masteron has a low toxicity profile, which enables it to be used for relatively long periods safely. However, like any potent androgen, Masteron will suppress natural testosterone production.

Comparison: Masteron P vs E

Masteron Propionate (P) vs. Masteron Enanthate (E): Both forms contain Drostanolone but differ in ester length and injection frequency. Propionate acts faster and requires more frequent injections, while Enanthate offers a slower, more sustained release, needing fewer injections.

Incorporating Masteron in Bodybuilding and Sports

As explained above Masteron has proven synergistic effects with other steroids. We'll continue and discuss below how to maximize Masteron's benefits for different purposes and users.

Dosage, Cycle Guidelines and Results

Beginners will find Masteron Prop valuable when combined with testosterone at moderate dosages. The properties of Masteron enhance the effect of testosterone, reduce estrogenic side effects, and help create a more muscular appearance with minimal additional side effects.
A typical beginner cycle includes 350-500mg per week of
Testosterone cypionate or enanthate, divided into bi-weekly injections, with Masteron at 50mg injected every other day or 100mg twice a week with the Testosterone.

Advanced users will appreciate Masteron in almost any cycle due to its unique traits. It particularly shines during the leaning phase, enhancing vascularity and a hardened muscle appearance. Masteron Prop has a proven synergistic effect when combined with Testosterone and Trenbolone. A typical advanced cycle of 10-12 weeks consists of 300-400mg/week of Testosterone Propionate, combined with 300-400mg/week of Trenbolone Acetate and 300mg/week of Masteron. This cycle can lead to dramatic improvements in condition and appearance, with significant body fat reduction and lean muscle mass gain if the diet is maintained properly.
