Product Overview
Masteron 100 mg by Dragon Pharma
Masteron 100 mg is an oil-based Drostanolone Propionate injectable manufactured by Dragon Pharma and dosed at 100 mg/mL in a 10 mL vial.
Drostanolone Propionate Injectable
Masteron 100 mg contains drostanolone propionate, a synthetic anabolic-androgenic steroid derived from dihydrotestosterone (DHT). Drostanolone is approximately 5 times as potent as natural methyltestosterone and binds to the androgen receptor, causing downstream genetic transcriptional changes that promote nitrogen retention, increase protein anabolism, and decrease amino acid catabolism. The propionate ester provides a shorter duration of action compared to longer-esterified compounds, requiring more frequent administration.
Drostanolone propionate has a historical medical application as an antineoplastic agent in the treatment of advanced breast neoplasms, where it was used to lower plasma cholesterol and inhibit the growth of estrogen receptor-presenting breast cancers. It is no longer actively marketed for human medical use in the United States. In non-medical bodybuilding contexts, Masteron 100 mg is commonly referenced for its ability to promote muscle hardness, density, and vascularity, particularly during cutting phases or pre-contest preparation when body fat levels are already low.
Drostanolone is a DHT derivative, which means it does not aromatize into estrogen. This characteristic is frequently cited in bodybuilding literature as a reason for its popularity during cutting cycles, where water retention and estrogenic side effects are undesirable. However, its androgenic nature means it can accelerate hair loss in predisposed individuals and may cause other androgen-related effects.
Key Benefits of Masteron 100 mg
- DHT-derived compound that does not aromatize to estrogen
- Supports muscle hardness and density during cutting phases
- Short propionate ester for rapid onset of action
- Commonly referenced for enhanced vascularity at low body fat
- MCT oil carrier for smooth injection
Carrier Oil
MCT Oil Formulation
Masteron 100 mg uses MCT oil as its carrier, providing an oil base for the drostanolone propionate formulation. The 100 mg/mL concentration is the standard strength for this compound.
Product Profile
Drostanolone Propionate Profile
Drostanolone propionate is a short-acting DHT-derived anabolic steroid with strong androgenic properties and no estrogenic activity. Its defining characteristic is the absence of aromatization, which makes it particularly suited for cutting and pre-contest applications in non-medical contexts.
DHT-Derived Short-Acting Anabolic Steroid
Drostanolone is a synthetic derivative of dihydrotestosterone, structurally modified with a 2-alpha-methyl group that increases its anabolic potency relative to DHT itself. Because DHT cannot be aromatized to estrogen, drostanolone shares this property and does not produce estrogenic side effects such as water retention or gynecomastia. The propionate ester attached to the 17-beta hydroxyl group further modifies its pharmacokinetic profile, producing a shorter duration of action than longer esters such as enanthate.
The compound binds to the androgen receptor and initiates genomic signaling that promotes anabolism in skeletal muscle. Its androgenic potency is relatively high compared to its anabolic activity, which explains its characteristic effects on muscle hardness and vascularity rather than large mass gains.
Historically, drostanolone propionate was approved under brand names including Drolban and Masteril for the treatment of advanced breast cancer in women. It is currently off-market for human medical use in the United States.
Release Profile
Short Propionate Ester
The propionate ester of Masteron 100 mg produces a relatively short duration of action, typically requiring administration every 1 to 2 days in non-medical contexts. This allows for more precise control of blood levels compared to longer-acting esters, though it also necessitates more frequent injections. Blood levels stabilize quickly after initiation, with users commonly referencing effects on muscle hardness and vascularity becoming apparent within the first few weeks of use.
Masteron 100 mg vs Other Dragon Pharma Preparations
Dragon Pharma offers a longer-acting version of this compound, Masteron 200, which contains drostanolone enanthate at 200 mg/mL. The enanthate ester provides a slower release profile and requires less frequent injections compared to the propionate ester in Masteron 100 mg. For those seeking a non-aromatizing oral option during cutting phases, Winstrol 50 is commonly referenced in bodybuilding contexts.
Masteron is frequently combined with other compounds in non-medical cutting cycles. Dragon Pharma's Anavar 10 is sometimes stacked with Masteron for enhanced muscle preservation during caloric restriction. For managing endogenous testosterone suppression, Proviron is also referenced in some contexts.
Dosage & Usage
Masteron 100 mg Dosage & Usage
The information below is provided for educational reference only. Drostanolone propionate is a prescription medication with limited current medical availability; medical use requires appropriate diagnosis, clinical supervision and ongoing monitoring. Non-medical use falls outside approved indications.
Typical Dosage Ranges
In non-medical bodybuilding contexts, Masteron 100 mg is commonly referenced in the range of 300–500 mg per week for intermediate users, with some experienced users referencing up to 600 mg per week. Because of its short propionate ester, the weekly total is typically divided into injections administered every other day. The 100 mg/mL concentration means that 1 mL provides 100 mg of drostanolone propionate, and users commonly administer 1–1.5 mL per injection.
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Cutting (non-medical) | 300–400 mg / week | Every other day |
| Pre-contest (non-medical) | 400–600 mg / week | Every other day or daily |
| Stacking with testosterone | Typically lower end of range | Per cycle protocol |
Stacking & Cycle Considerations
In non-medical bodybuilding contexts, drostanolone propionate is most commonly referenced as a cutting or pre-contest compound. It is frequently stacked with a testosterone base, which provides the anabolic foundation and maintains normal physiological function. Dragon Pharma's Cypionate 250 or Enantat 250 are commonly mentioned in this context.
Because Masteron does not aromatize, it may reduce or eliminate the need for aromatase inhibitors when stacked with moderate doses of testosterone. Cycle lengths of 6–10 weeks are commonly referenced in non-medical contexts, with the compound typically introduced during the final weeks of a cutting phase when body fat is already low.
Managing Side Effects
As a DHT derivative, drostanolone propionate can accelerate male pattern baldness in individuals who are genetically predisposed. Acne and increased skin oiliness are also commonly referenced. Unlike aromatizing compounds, it does not cause water retention or gynecomastia.
Drostanolone can negatively affect lipid profiles, reducing HDL cholesterol and potentially increasing LDL. Blood pressure and cardiovascular markers should be monitored during use. Because it suppresses endogenous testosterone production, some form of recovery support is typically referenced after a cycle.
Post-Cycle Therapy (PCT)
After completing a cycle with Masteron 100 mg, post-cycle therapy is commonly recommended in non-medical contexts to help restore endogenous testosterone production. Agents such as Clomid or Nolvadex are frequently referenced for this purpose.
Because drostanolone propionate has a short half-life, PCT can typically begin sooner after the final injection compared to longer-acting compounds. Bloodwork and, where possible, medical guidance can help inform recovery strategy.

Safety & Information
Drostanolone Propionate Safety Information
Drostanolone propionate is a synthetic anabolic steroid that can affect cardiovascular, hepatic, endocrine and reproductive function. It is no longer actively marketed for human medical use in the United States.
Important Safety Information
Drostanolone propionate was historically approved for the treatment of advanced breast cancer in women, where its virilizing effects limited its clinical usefulness. It is currently classified as off-market for human use by DrugCentral. Non-medical use for bodybuilding or performance enhancement falls outside approved indications and may carry significant health risks.
Anabolic steroids in general have been associated with serious adverse effects including hepatic dysfunction, cardiovascular complications, and endocrine disruption. Drostanolone's androgenic nature means it carries particular risks related to hair loss and virilization.
Important
Non-Medical Use
Use of drostanolone propionate for bodybuilding or performance enhancement falls outside approved medical indications. Higher-than-physiologic exposure can increase the risk of serious adverse effects including cardiovascular, hepatic and endocrine complications.
Potential Adverse Effects
As a DHT derivative, drostanolone propionate is associated with androgenic side effects including accelerated male pattern baldness, acne, and increased body hair growth. In women, virilization signs such as deepening of the voice, hirsutism, and clitoromegaly may occur and can be irreversible.
Anabolic steroids including drostanolone have been reported to affect lipid profiles, with reductions in HDL cholesterol and potential increases in LDL. These changes may have a serious impact on cardiovascular risk.
Drostanolone suppresses endogenous testosterone production, which can lead to sexual dysfunction and testicular atrophy during use. Other potential effects include mood changes, irritability, and elevated blood pressure.
Conditions Requiring Medical Evaluation
Drostanolone propionate is contraindicated in certain circumstances. Known contraindications include prostate cancer, male breast cancer, pregnancy or potential for pregnancy, and known hypersensitivity to drostanolone. Caution is advised in individuals with pre-existing cardiovascular disease, hepatic impairment, or significant hair loss concerns.
Existing cardiovascular disease, liver conditions, prostate conditions, and other medical conditions should be discussed with a qualified healthcare professional before drostanolone is considered.
Monitoring During Use
If drostanolone propionate is used in any context, monitoring of lipid profiles and cardiovascular markers is important given the compound's known effects on HDL cholesterol. Liver function and hematocrit may also warrant monitoring. In non-medical bodybuilding contexts, bloodwork before, during, and after a cycle is commonly referenced as a risk-reduction strategy.

Agents such as Clomid or Nolvadex are commonly referenced for this purpose. Because of the short ester, PCT can typically begin sooner than with longer-acting compounds.
What does drostanolone propionate do?
Drostanolone propionate is a DHT-derived anabolic steroid that binds to the androgen receptor and promotes nitrogen retention, increases protein anabolism, and decreases amino acid catabolism. It does not aromatize to estrogen, which distinguishes it from testosterone and many other anabolic steroids.
How long does drostanolone propionate take to work?
Because of its short propionate ester, drostanolone propionate reaches stable blood levels relatively quickly. In non-medical contexts, users commonly reference noticing effects on muscle hardness and vascularity within the first few weeks of use, particularly when body fat is already low.
Is Masteron 100 mg the best cutting compound?
There is no single compound that is universally best for cutting. Masteron 100 mg is commonly referenced in bodybuilding contexts for its ability to promote muscle hardness and vascularity without water retention. Other products such as Winstrol 50 and Anavar 10 are also referenced for cutting purposes.
What is the difference between Masteron 100 and Masteron 200?
The primary difference is the ester and concentration. Masteron 100 mg contains drostanolone propionate at 100 mg/mL, which is a short-acting ester. Masteron 200 contains drostanolone enanthate at 200 mg/mL, which is a longer-acting ester requiring less frequent injections. Both ultimately provide the same parent hormone, drostanolone.
What is the difference between Masteron and Proviron?
Masteron 100 mg contains drostanolone propionate, an injectable DHT-derived anabolic steroid. Proviron contains mesterolone, an oral DHT-derived compound with different pharmacokinetic properties. Both are referenced in bodybuilding contexts, but they have distinct administration routes and characteristics.
Is 100 mg of Masteron a lot?
A milligram amount cannot be classified as appropriate or excessive without considering the specific context, individual response, and other factors. In non-medical bodybuilding contexts, drostanolone propionate is commonly referenced in the 300–500 mg per week range, divided into frequent injections. Such use falls outside approved indications.
What strength is Masteron 100 mg?
Masteron 100 mg is labeled at 100 mg of drostanolone propionate per mL. It is supplied in a 10 mL vial, giving 1,000 mg of total labeled drostanolone propionate content per vial.
Is Masteron 100 mg suitable for beginners?
Drostanolone propionate is generally referenced as an intermediate-to-advanced compound in non-medical bodybuilding contexts. Its androgenic nature and the frequency of injection required with the propionate ester make it less suitable as a first compound. Users typically have experience with testosterone-based cycles before considering Masteron.
What carrier oil does Masteron 100 mg use?
Masteron 100 mg uses MCT oil as its carrier. The oil base is designed to support the 100 mg/mL concentration of drostanolone propionate in a stable injectable formulation.
