Deus Medical Mastermed P 100 is a 100mg/ml injectable preparation of drostanolone propionate supplied in a 10ml vial. This product is intended strictly for laboratory research and analytical study. It is not a medicine, food supplement or cosmetic. Researchers looking for a precisely dosed, single-ester reference material will find Mastermed P 100 useful for controlled in-vitro work.
Drostanolone propionate is a short-ester compound. Its propionate ester is relatively small, so it is typically studied in short observation windows rather than long protocols. For this reason, Mastermed P 100 is often chosen when a researcher needs a fast-acting reference rather than a long-lasting depot. If you want to understand how ester length affects release profiles, you can read more about drostanolone propionate on Wikipedia.
Why Researchers Choose Deus Medical Mastermed P 100
Deus Medical has built a reputation for consistent dosing and clean presentation. Mastermed P 100 continues that approach. Each vial is filled to 10ml at a stated concentration of 100mg/ml, giving a total of 1,000mg of active material per vial. That makes it straightforward to calculate dilutions and prepare working solutions.
The oil carrier is designed to flow smoothly through a standard needle. This reduces handling time and helps keep samples consistent between batches. In addition, the rubber stopper and crimp seal are chosen to protect the contents during storage and transport.

Handling and Storage Guidelines
Proper handling protects both the sample and the researcher. Before opening, inspect the vial for cracks, cloudiness or a damaged seal. If the seal is broken or the solution looks unusual, do not use it. Instead, set it aside for disposal according to your laboratory rules.
Store Mastermed P 100 upright at room temperature. Avoid direct sunlight, which can degrade the ester over time. Do not freeze the vial. Freezing can cause the oil to separate and may damage the stopper. If the solution becomes cloudy in cold weather, allow it to warm slowly to room temperature and inspect it again.
When drawing a sample, use a clean needle and work in a sterile environment. Wipe the stopper with an alcohol swab and let it dry before piercing. Never reuse a needle. Record the batch number and date on your sample log so your results stay traceable.
How Mastermed P 100 Fits Into a Research Plan
Short-ester compounds are often used in studies that need tight control over timing. Because the propionate ester clears relatively quickly, researchers can adjust exposure windows without waiting weeks for a long depot to fade. This makes Mastermed P 100 a practical reference when comparing ester release rates.
If your work involves broader metabolic or hormonal pathways, you may also need supporting reference materials. For example, many labs pair androgen research with studies on body composition and recovery. You can explore related research tools such as a post cycle therapy research pack or a beginner research cycle to build a complete study design.
Researchers working on weight-management pathways may also need comparator compounds. Products such as Retatrutide 10mg vials or Wegovy semaglutide 1mg are often used in adjacent metabolic studies. Always check local rules before ordering any research material.
Quality, Testing and Documentation
Deus Medical products are produced in controlled facilities. Each batch is checked for concentration and sterility before release. However, no supplier can replace your own due diligence. A good practice is to verify the batch number, check the vial appearance and, where possible, run your own analytical test such as HPLC or mass spectrometry.
Independent testing is the backbone of reproducible science. If you want to learn how purity is measured, the National Institute of Standards and Technology (NIST) publishes useful reference material on analytical methods. Following recognised methods helps you compare results across batches and suppliers.
What to look for in a good vial
- Clear, consistent oil with no particles
- Intact aluminium crimp and clean stopper
- Legible batch and expiry information
- No leakage around the seal
- Vial filled to the stated 10ml mark
Frequently Asked Questions
Is Deus Medical Mastermed P 100 a medicine?
No. It is sold strictly as a laboratory research material. It is not approved for human or veterinary use and must not be consumed.
What is the difference between propionate and other esters?
The propionate ester is short. It is typically studied over shorter time frames than longer esters such as enanthate or decanoate.
How should I store the vial?
Keep it upright at room temperature, out of direct light. Do not freeze it. Check the solution before each use.
Do you ship within the UK?
Yes. Orders are packed discreetly and dispatched from the UK. Delivery times vary by location, so check the shipping page at checkout.
Can I combine it with other research compounds?
Only you can decide what is appropriate for your study. Always follow your institution’s safety rules and local laws.
