Masteron, known generically as Drostanolone, is an anabolic androgenic steroid derived from DHT that’s used primarily in the world of bodybuilding. The compound comes in two primary variants based on its ester: Masteron Propionate and Masteron Enanthate.

Chemical Structure and Properties

Drostanolone, the parent hormone of Masteron, is a DHT (dihydrotestosterone) derivative. Its anabolic rating is significantly higher than testosterone, which provides the muscle-enhancing effects sought after by bodybuilders. The androgenic rating of Masteron is also substantial, though it does not convert to estrogen, minimizing certain side effects. The variation between Masteron’s forms lies in their attached ester, which affects the drug’s release time and duration of action in the body.

  • Masteron (Drostanolone)
    • Chemical Name: 2alpha-methyl-androstan-3-one-17beta-ol
    • Anabolic Rating: 62-130
    • Androgenic Rating: 25-40

Masteron Propionate vs. Masteron Enanthate

The primary difference between the two variants of Masteron lies in their ester. Drostanolone Propionate, often referred to as Masteron Propionate, is the faster-acting version that requires more frequent injections to maintain stable blood levels. It has a shorter half-life, typically requiring administration every other day.

Masteron Propionate:

  • Ester: Propionate
  • Half-life: 2.5 days

In contrast, Drostanolone Enanthate, known as Masteron Enanthate, has a longer ester and therefore a longer half-life, allowing for less frequent injections. This variant is often used by bodybuilders during longer cycle periods and is known for its slower, but steadier release.

Masteron Enanthate:

  • Ester: Enanthate
  • Half-life: ~10 days

Both forms exert similar effects in terms of anabolic and androgenic activity, but their pharmacokinetics dictate the frequency of dosing and the rate at which effects become evident.

Masteron E Guide – Cycle and Dosage

Masteron E Guide - Cycle and Dosage.

When considering a Masteron Enanthate (Drostanolone Enanthate) cycle, it’s essential to address the appropriate dosage, cycle length, combination with other steroids, and adjustments for various levels of experience.

Optimal Dosage and Cycle Length

The optimal dosage for Masteron Enanthate typically ranges from 300 to 400mg per week. For most users, a cycle length of 6 to 12 weeks is common. It’s crucial to adhere to these guidelines to balance effectiveness with the potential for side effects.

  • Beginner: 300mg/week for 8-10 weeks
  • Intermediate: 350mg/week for 10-12 weeks
  • Advanced: 400mg/week for 10-12 weeks

Stacking with Other Steroids

Masteron Enanthate is often stacked with other steroids to enhance results.

  • With Testosterone Propionate:
    • Stack: 300mg/week Masteron E + 100mg/eod Testosterone Propionate
  • With Trenbolone:
  • With Anavar or Winstrol (for cutting):
    • Stack: 300mg/week Masteron E + 50mg/day Anavar or 50mg/day Winstrol

Customizing Your Cycle: Beginner to Advanced

Customization of the cycle should account for the user’s experience with steroid cycles.

  • Beginner: A Test cycle with Testosterone Enanthate at 500mg/week alongside Masteron E can be a good start.
  • Intermediate: Introduction of Tren, with a focus on monitoring side effects and adjusting as necessary.
  • Advanced: Users may combine higher dosages of Masteron with multiple compounds, adjusting dosages based on previous experiences.

Performance and Physique Enhancements

Masteron E enhances muscle definition and supports fat loss, making it a staple in bodybuilding cycles aimed at achieving a sharp and lean physique.

Benefits in Muscle Hardening and Fat Loss

Masteron E is known for its ability to improve muscle hardness and density. It interacts with androgen receptors to increase protein synthesis and muscle contractility, contributing to a more pronounced muscle definition. This anabolic steroid is particularly popular during cutting phases of training, where the goal is to maintain muscle mass while reducing body fat.

Body Fat Reduction and Lean Muscle Preservation

When bodybuilders aim to lose body fat, maintaining lean muscle mass becomes a priority. Masteron E aids in preserving lean muscle tissue, even in a calorie deficit, due to its anti-catabolic properties. Additionally, it has a reputation for facilitating the metabolism of body fat, serving as a valuable tool for athletes in cutting cycles who seek to maintain strength and muscle mass while stripping away excess fat.

Potential Side Effects and Management

Deca Durabolin Side Effects

Masteron Enanthate, known in the bodybuilding community for its muscle-enhancing effects, carries a risk of side effects. It’s imperative to understand these risks and manage them proactively.

Estrogenic and Androgenic Complications

Masteron E, being a derivative of dihydrotestosterone (DHT), does not aromatize or convert to estrogen. Therefore, estrogenic side effects like gynecomastia and water retention are unlikely. However, androgenic side effects such as increased aggression and libido changes may occur. The risk of these effects can be heightened in individuals sensitive to androgenic compounds. Management of these side effects often entails the use of 5-alpha reductase inhibitors or similar medications, which can reduce the androgenic activity of the steroid.

Implications for Cholesterol and Cardiovascular Health

The use of Masteron E can have a negative impact on cholesterol levels. It can potentially lower HDL (the “good” cholesterol) and increase LDL (the “bad” cholesterol), which in turn might affect blood pressure and overall cardiovascular health. For managing these risks, a diet high in omega fatty acids, regular cardiovascular exercise, and monitoring cholesterol levels is advised. In some instances, cholesterol management medications may be necessary under medical supervision.

Addressing Hair Loss and Skin Changes

The androgenic nature of Masteron E can also lead to skin changes like acne and accelerated hair loss in genetically predisposed individuals. Skincare routines including mild cleansers and the use of topical treatments for acne may help manage skin-related side effects. Hair loss can be difficult to treat, although products containing minoxidil may offer some benefit. For both acne and hair loss, it is crucial to balance the steroid’s advantages against the potential for these cosmetic side effects.

Post Cycle Therapy and Recovery


After a Masteron E cycle, implementing a strategic post cycle therapy (PCT) is critical to help the body restore its natural hormone levels and preserve muscle gains.

Protocols for Hormonal Rebalancing

In post cycle therapy, the primary objective is to stimulate the body’s natural production of testosterone. Clomid (Clomiphene Citrate) and Nolvadex (Tamoxifen Citrate) are commonly used for this purpose. A typical PCT regimen may begin within one to two weeks after the last steroid injection and can last between 4 to 6 weeks. Dosage protocols may start higher and taper down throughout the course of PCT to support gradual hormonal rebalancing. For example:

  • Weeks 1-2: Clomid 50mg daily, Nolvadex 40mg daily
  • Weeks 3-4: Clomid 25mg daily, Nolvadex 20mg daily

HCG (Human Chorionic Gonadotropin) might also be employed to stimulate the testes directly, aiding in testosterone production before the above agents are used. It’s often administered before Clomid or Nolvadex to kickstart the testicular response.

Role of PCT in Preserving Muscle Gains

PCT is essential to prevent a significant post-cycle muscle loss. By restoring endogenous testosterone production, PCT helps maintain the muscle mass acquired during the steroid cycle. Without PCT, cortisol levels can rise, potentially leading to catabolism where muscle tissue is broken down. A balanced PCT protocol enables individuals to retain gains by normalizing the body’s hormonal environment which promotes recovery and homeostasis.
