Dragon Pharma Masteron 200 mg Lab Reports
Published lab reports for Dragon Pharma Masteron 200 mg are provided below with the test date, measured result and reported batch number. Each result can be compared directly with the product's labeled strength of 200 mg/mL.
Masteron 200 mg contains drostanolone with an enanthate ester attached. The enanthate ester provides a longer-acting release profile compared with the propionate ester, while the product strength indicates how much drostanolone enanthate is present in each milliliter.
1
Drostanolone + Enanthate
The enanthate ester makes drostanolone oil-soluble and suitable for an injectable formulation with a longer-acting release profile.
2
Gradual Release
The enanthate ester provides a longer-acting release of drostanolone compared with the shorter-acting propionate ester.
3
Active Drostanolone
After the ester is separated, the released drostanolone acts as the active compound.
What the Enanthate Ester Does
Enanthate is the ester attached to the drostanolone molecule. Its main role is to slow release from the injection site, providing a longer-acting profile compared with the propionate ester. This means the release of drostanolone is more gradual over time than with the shorter-acting propionate version.
Once the ester is separated, the active compound is drostanolone. Drostanolone is a DHT-derivative with a modified chemical structure that distinguishes it from testosterone and other anabolic steroids.
Ester vs. Product Strength
The ester and the concentration describe different aspects of the product. The ester influences release characteristics, while the concentration states how much drostanolone enanthate is contained in each milliliter.
Dragon Pharma Masteron 200 mg is labeled at 200 mg/mL and supplied in a 10 mL vial. This gives a total labeled content of 2,000 mg of drostanolone enanthate per vial.
Medical and Research References
Drostanolone has been studied in various contexts. Published research provides useful background on the compound and its pharmacology.
Drostanolone is a synthetic anabolic-androgenic steroid with significant safety considerations. A laboratory report confirms information about the tested sample, but it does not determine whether drostanolone use is safe or appropriate for an individual.
Cardiovascular Effects
Drostanolone can affect lipid profiles, including reducing HDL (good) cholesterol levels, and may influence blood pressure. These factors should be considered when assessing cardiovascular risk.
Hematocrit and Blood Changes
Drostanolone can increase red blood cell production and hematocrit. This may require monitoring, particularly in individuals with existing blood disorders or cardiovascular conditions.
Hormonal Effects and Fertility
Drostanolone can suppress natural testosterone production and affect fertility. Androgenic effects such as acne and hair changes may also occur.
Liver Health
Drostanolone can affect liver function. Monitoring of liver enzymes may be appropriate during use. Symptoms such as jaundice or dark urine should be evaluated promptly.
Mood and Sleep
Reported effects can include mood changes and sleep disturbances. New, persistent or severe symptoms should be discussed with a healthcare professional.
Injection-Specific Risks
As with any injectable product, appropriate injection technique and hygiene are required to reduce the risk of infection or injection-site reactions. Use sterile equipment and proper technique.
Conditions That Require Medical Review
Drostanolone should be avoided or used only under close medical supervision in individuals with existing cardiovascular disease, liver disease, prostate issues, elevated hematocrit, cholesterol abnormalities, kidney problems, or mental health conditions.
The product should be stored securely to prevent accidental access or use by children or other household members. Drostanolone exposure during pregnancy is contraindicated and can harm fetal development.
When to Seek Urgent Medical Help
Seek urgent medical attention for symptoms such as chest pain, sudden shortness of breath, fainting, one-sided weakness, severe headache, major vision changes, a painful or swollen leg, jaundice, dark urine, persistent nausea, upper abdominal pain, signs of a serious allergic reaction, or a rapidly worsening injection-site reaction.
Tested Sport
Drostanolone is a prohibited substance under anti-doping rules in tested sport at all times.

Two published reports are available. The latest, dated March 25, 2026, measured 199.24 mg/mL for batch #MASTMT6. This corresponds to approximately 99.62% of the stated 200 mg/mL concentration. An earlier report from November 19, 2025, measured 199.21 mg/mL for the same batch.
Does a lab report verify every vial?
No. Each report applies to the sample submitted for that specific test and the batch identified in the report. It does not independently verify the content or condition of every individual vial.
How should Masteron 200 mg be stored?
Keep the vial in its original packaging and follow the storage directions printed on the product label. Protect it from excessive heat, moisture and direct light, and keep it securely out of reach of children and pets.
