Masteron P 100

Dragon Pharma Masteron P 100 (Drostanolone Propionate 100mg) Overview | iRoids Pharma

Dragon Pharma Masteron P 100 is an injectable anabolic steroid manufactured by Dragon Pharma. Each milliliter contains 100mg of Drostanolone Propionate, the short-acting propionate ester form of Drostanolone. At iRoids Pharma, we carry Dragon Pharma Masteron P 100 as part of our injectable anabolic steroid inventory for customers in markets where Drostanolone Propionate is legally available. Drostanolone Propionate is the original Masteron formulation, predating the longer-acting Drostanolone Enanthate version, and carries the more established historical presence in both clinical medicine and bodybuilding communities. Like all anabolic steroid products, Dragon Pharma Masteron P 100 carries significant health and legal considerations that anyone researching it should understand clearly before forming an opinion about it.

Drostanolone has a documented history in clinical medicine where physicians originally prescribed it as an anti-estrogen treatment for inoperable breast cancer in women. This clinical background distinguishes it from compounds with no legitimate medical history. Over time, clinical use declined as more effective breast cancer treatments became available. Despite this, Drostanolone remains one of the most consistently discussed injectable anabolic steroids in performance and bodybuilding communities due to its specific pharmacological characteristics, non-aromatizing profile, and well-documented presence in competitive bodybuilding literature.

What Is Drostanolone Propionate

Drostanolone Propionate is a synthetic anabolic androgenic steroid derived from dihydrotestosterone. The propionate ester attached to the Drostanolone base is a short-acting ester with a half-life of approximately 2 to 3 days. As a result, it releases testosterone more rapidly from the injection site and clears the system faster than the longer-acting Drostanolone Enanthate form. This shorter half-life requires more frequent injection compared to Masteron Enanthate but also means the compound clears the system significantly faster after the last injection.

Drostanolone does not aromatize to estrogen. Unlike testosterone and many other anabolic steroids, it does not convert to estrogen through the aromatase enzyme. Furthermore, Drostanolone actively inhibits the aromatase enzyme to a degree, producing mild anti-estrogenic effects in the body. This characteristic gives it a distinct pharmacological profile compared to most other anabolic steroids and is one of the primary reasons it originally attracted clinical interest as a breast cancer treatment.

Propionate Versus Enanthate Ester

The propionate ester is the original and historically more established Masteron formulation. Its shorter half-life of 2 to 3 days contrasts with the enanthate ester’s half-life of approximately 10 to 12 days. In harm reduction discussions, the propionate ester’s faster clearance is cited as an advantage for monitoring side effects and discontinuing use more quickly if problems arise. The enanthate form, in contrast, provides the convenience of less frequent injection. Both use the same Drostanolone base compound and produce the same pharmacological effects.

Clinical Background of Drostanolone

Drostanolone was originally developed and prescribed as a treatment for inoperable breast cancer in women. Its anti-estrogenic properties made it a relevant therapeutic option before modern selective estrogen receptor modulators and aromatase inhibitors became the standard of care. Clinical use in this application documented the compound’s anti-estrogenic activity and provided a research base that informed later discussions about its pharmacological properties.

As more effective and targeted breast cancer treatments became available, clinical use of Drostanolone declined significantly. Most regulatory approvals lapsed over time, and the compound no longer holds active clinical approval in most jurisdictions. However, its documented clinical history gives it a more established research base than compounds with no legitimate medical background.

Why Dragon Pharma Masteron P 100 Appears in Bodybuilding Discussions

Drostanolone Propionate occupies a specific position in bodybuilding discussions. Its pharmacological profile makes it a consistent topic in discussions about body composition, estrogen management, and competitive physique preparation.

Non-Aromatizing and Anti-Estrogenic Profile

The most consistently referenced characteristic of Drostanolone Propionate in bodybuilding literature is its non-aromatizing and mildly anti-estrogenic profile. Because it does not convert to estrogen and actively inhibits aromatase activity, users do not experience estrogen-related side effects from Drostanolone Propionate use. Furthermore, its mild anti-estrogenic activity is discussed in bodybuilding communities in the context of managing estrogen levels when used alongside aromatizing compounds like testosterone.

Hardening Effect on Physique

Drostanolone is frequently discussed in bodybuilding communities in the context of producing a harder and drier physical appearance compared to compounds that cause water retention. The absence of estrogen-related water retention associated with non-aromatizing compounds contributes to this characteristic. This hardening effect is one of the most consistently cited reasons for Drostanolone’s presence in discussions about competition preparation and physique development.

Short Acting Profile

The propionate ester’s short half-life of 2 to 3 days is a frequently discussed characteristic in performance communities. The faster clearance compared to the enanthate form is cited in harm reduction discussions as an advantage for monitoring side effects. Furthermore, the shorter active window means changes in response to the compound are detectable more quickly than with longer-acting ester versions.

Androgenic Activity

Despite carrying a lower androgenic rating than testosterone, Drostanolone Propionate produces meaningful androgenic effects due to its dihydrotestosterone base. These androgenic effects contribute to increased muscle density and strength that bodybuilding communities frequently reference alongside the compound’s aesthetic characteristics.

Low Liver Toxicity

Injectable Drostanolone Propionate does not carry the liver toxicity associated with 17-alpha alkylated oral anabolic steroids. This characteristic contributes to its discussion in harm reduction contexts where minimizing organ stress is a relevant consideration.

Masteron P 100 Versus Masteron Enanthate 200

Understanding how Dragon Pharma Masteron P 100 compares to Masteron Enanthate helps clarify its specific position for anyone evaluating both options.

Ester and Half-Life

Masteron P 100 uses a short-acting propionate ester with a half-life of approximately 2 to 3 days. Masteron Enanthate uses a long-acting enanthate ester with a half-life of approximately 10 to 12 days. As a result, Masteron P 100 requires significantly more frequent injection compared to Masteron Enanthate to maintain stable plasma concentrations.

Injection Frequency

The practical injection frequency difference is a primary discussion point between the two forms. Masteron P 100 requires more frequent injections due to its short half-life. Masteron Enanthate requires less frequent administration, making it more convenient for many users. However, the more frequent injection requirement of Masteron P 100 is offset by its faster clearance advantage in harm reduction contexts.

Clearance Rate

Masteron P 100 clears the system significantly faster than Masteron Enanthate due to its shorter half-life. This faster clearance is cited in harm reduction discussions as an advantage for monitoring side effects and discontinuing use more quickly if problems arise. After the last injection, Masteron Propionate clears the system in approximately one week compared to several weeks for Masteron Enanthate.

Concentration Difference

Dragon Pharma Masteron P 100 contains 100mg of Drostanolone Propionate per milliliter. The Sixpex Masteron Enanthate 200 product available at iRoids Pharma contains 200mg of Drostanolone Enanthate per milliliter. The higher concentration per milliliter of the enanthate version reduces injection volume requirements compared to the propionate version.

Risks and Health Considerations

Dragon Pharma Masteron P 100 carries a real risk profile. Anyone researching this compound should understand these risks clearly before proceeding.

Androgenic Side Effects

Despite carrying lower androgenic activity than testosterone, Drostanolone Propionate still produces androgenic side effects. These include acne, oily skin, and accelerated male pattern baldness in genetically predisposed individuals. Because Drostanolone is derived from dihydrotestosterone, it is not subject to conversion by 5-alpha reductase and acts as a potent androgen at the hair follicle level. Individuals with a family history of male pattern baldness should consequently pay particular attention to this risk.

Cardiovascular Effects

Drostanolone Propionate negatively affects cholesterol levels. Clinical research and user reports document reductions in HDL cholesterol and elevations in LDL cholesterol with Drostanolone use. These lipid changes carry cardiovascular implications. Regular lipid panel monitoring is therefore important for anyone using this compound under medical supervision.

Hormonal Suppression

Exogenous Drostanolone Propionate suppresses natural testosterone production through feedback inhibition of the hypothalamic-pituitary-gonadal axis. The degree of suppression varies between individuals and depends on duration of use. Natural hormonal function may require medical support to restore after discontinuation.

Injection Site Considerations

As an injectable compound, Dragon Pharma Masteron P 100 carries risks associated with intramuscular injection. These include injection site pain, infection risk from non-sterile technique, and tissue damage from repeated injections at the same site. The propionate ester is associated with more injection site irritation than longer-acting esters in many user reports. Sterile injection technique and site rotation are therefore important considerations for anyone administering injectable compounds.

Virilization in Women

Drostanolone Propionate carries a significant risk of virilization in women including voice deepening, clitoral enlargement, increased body hair growth, and disruption of the menstrual cycle. These effects may be irreversible with prolonged use. Women researching this compound should therefore be particularly aware of these risks.

Legal Status

Drostanolone Propionate carries Schedule III controlled substance status in the United States. A valid prescription from a licensed physician is required for legal possession and use. Legal status varies by country. Research the legal status in your specific jurisdiction before purchasing from iRoids Pharma.
