Viogen Masteron Enanthate 225mg is a high-strength injectable anabolic compound supplied in a 10ml multi-dose vial. Each millilitre delivers 225mg of drostanolone enanthate, a long-ester derivative of the popular Masteron hormone. Because of this, the product is popular among experienced researchers who study lean muscle retention, hardness and oestrogen control in laboratory settings. This listing is intended for research purposes only and is not a medicine for human consumption.
What Is Viogen Masteron Enanthate 225mg?
Masteron is the common trade name for drostanolone, a synthetic anabolic androgenic steroid first described in the late 1950s. The enanthate ester extends its half-life, so it stays active in the body for longer than the short-acting propionate version. Viogen has concentrated the formula to 225mg per ml, which means fewer injections and a lower oil volume per dose.
Drostanolone does not aromatise, so it does not convert into oestrogen. For that reason, it is often studied alongside compounds that do, such as testosterone. According to Wikipedia’s overview of drostanolone, the drug was originally investigated for breast cancer treatment before gaining popularity in bodybuilding research.

Why Researchers Choose the Enanthate Ester
Ester selection matters in any research protocol. The enanthate version of Masteron is released more slowly than propionate, which produces steadier blood levels. In practice, that means fewer injections per week and less fluctuation between peaks and troughs.
Concentration also plays a role. At 225mg per ml, Viogen’s formula lets a researcher deliver a meaningful dose in a smaller volume of oil. This can reduce injection site discomfort and make a cycle easier to plan. If you are comparing options, you can view a related enanthate-ester product here to see how the two compare.
Common Research Applications
Lean Muscle and Hardness Studies
Masteron is best known for its ability to promote a dry, hard look in research models. It does not cause water retention, so it is often included in cutting-phase protocols rather than bulking ones.
Oestrogen Management Research
Because drostanolone does not aromatise, it is frequently studied alongside aromatising compounds. Researchers may pair it with testosterone to observe how the ratio of androgenic to oestrogenic activity affects results.
Stacking Protocols
Many laboratory protocols combine Masteron with other injectables. A well-designed synergy stack can help researchers study how multiple compounds interact over a set period. Beginners, however, should start with a simpler plan such as a structured beginner cycle before adding more variables.
Dosage and Administration in Research
Dosage depends entirely on the study design, the experience level of the researcher and the other compounds involved. Typical research notes for Masteron Enanthate range from 200mg to 600mg per week, split into two or three injections. Because the ester is long, a researcher may inject every three to four days rather than daily.
Always follow your institution’s safety guidelines. Use sterile technique, rotate injection sites and never share equipment. For general information on safe injection practice, see the NHS guidance on steroid injections.
Potential Side Effects to Monitor
As with any anabolic compound, side effects are possible. Researchers should monitor for:
- Androgenic effects such as acne or hair thinning
- Changes in cholesterol and lipid profile
- Blood pressure elevation
- Suppression of natural testosterone production
Regular blood work is strongly advised. Post-cycle support is also important; a post-cycle therapy plan can help restore normal function after a study concludes.
Storage and Handling
Store the vial upright at room temperature, away from direct sunlight. Do not freeze. Before use, inspect the solution for particles or discolouration. If the oil looks cloudy or contains debris, discard it. Keep the vial out of reach of children and pets.
Frequently Asked Questions
Is Viogen Masteron Enanthate 225mg legal in the UK?
In the UK, anabolic steroids are Class C controlled substances when intended for human use. They are legal to possess for personal use but illegal to sell or supply. This product is listed strictly for laboratory research purposes.
How long does shipping take?
UK orders are typically dispatched the same day if placed before the cut-off. Next-day delivery is often available. See the same-day delivery options page for more details on dispatch times.
Can I stack it with other compounds?
Yes, many protocols combine Masteron with testosterone or other injectables. However, stacking increases complexity and risk. Review the beginner stack guide before combining multiple products.
What is the difference between Masteron Propionate and Enanthate?
The main difference is the ester. Propionate acts faster and requires more frequent injections, while enanthate is slower and requires fewer. Both use the same active hormone.
