Masteron Propionate (Proton Pharma Drostex) – 10 x 100mg/ml Ampules
Masteron Propionate, also known as Drostanolone Propionate or Mast P by athletes and researchers, is a fast-acting anabolic compound supplied here in a pack of 10 sterile 1ml ampules, each containing 100mg of active ingredient. Manufactured by Proton Pharma under the Drostex label, this product is intended strictly for laboratory research and analytical study. If you are searching for a reliable UK source of Masteron Propionate, this presentation offers consistent dosing and high purity in a convenient ampule format.
Drostanolone Propionate is a derivative of dihydrotestosterone (DHT) and is widely studied for its interaction with androgen receptors. Its propionate ester gives it a relatively short half-life, which makes it a common subject in research models examining ester cleavage and release kinetics. Each ampule is filled to 1ml with 100mg of the compound, allowing precise measurement for in-vitro and analytical applications.
Why Researchers Choose Proton Pharma Drostex
Proton Pharma has built a reputation among UK laboratories for producing consistently dosed injectable research chemicals. The Drostex line is no exception. Every batch of Masteron Propionate is manufactured under strict quality control and undergoes third-party testing to verify concentration and sterility. This means you receive exactly what the label states: 100mg of drostanolone propionate per 1ml ampule, with no underdosing or contaminants.
The ampule format is another advantage. Unlike multi-use vials, each 1ml glass ampule is sealed under sterile conditions, eliminating the risk of repeated punctures and cross-contamination during storage. For researchers who require single-use aliquots, this packaging is ideal.

Understanding Masteron Propionate in Research
Masteron Propionate is frequently included in studies exploring androgen receptor binding affinity, muscle protein synthesis pathways, and the effects of DHT-derived compounds on various tissue models. Its short ester means it is cleared more rapidly than enanthate or decanoate versions, which can be advantageous when researchers need to observe acute responses or maintain tighter control over concentration curves.
According to Wikipedia’s entry on drostanolone propionate, the compound is a synthetic androgen and anabolic steroid that is not approved for human use in many jurisdictions, which underscores its status as a research chemical. For a broader understanding of anabolic steroids and their classification, the National Institutes of Health (NIH) provides extensive resources on steroid biochemistry. Researchers should also consult the UK Government’s guidance on controlled substances to ensure compliance with local laws.
Typical Research Applications
In laboratory settings, Masteron Propionate may be used to investigate:
- Androgen receptor-mediated gene expression
- Ester hydrolysis rates and pharmacokinetic profiles
- Comparative studies with other DHT derivatives
- Analytical method development for steroid detection
It is important to note that this product is not for human or veterinary use. It is supplied exclusively for in-vitro research and analytical purposes.
Dosage and Administration (Research Context)
As a research chemical, there is no established human dosage. However, published studies often reference concentrations in the range of 50–100mg per administration in animal models, though these are not directly translatable to human use. Researchers should determine appropriate experimental doses based on their specific protocols and institutional guidelines.
The propionate ester typically requires more frequent administration in research settings compared to longer esters. When designing a study, consider the half-life of drostanolone propionate, which is approximately 2–3 days. This shorter duration allows for rapid clearance and easier monitoring of acute effects.
Storage and Handling
To maintain stability and sterility, store Masteron Propionate ampules in a cool, dark place, ideally between 15°C and 25°C. Avoid freezing, as temperature fluctuations can cause the compound to crystallise or degrade. Before use, inspect each ampule for cracks or particulate matter. If particles are present, do not use the product. Always follow standard laboratory safety procedures when handling injectable research chemicals, including the use of gloves and eye protection.
Frequently Asked Questions
Is Masteron Propionate legal in the UK?
Masteron Propionate is classified as a Class C controlled substance in the UK when intended for human use. However, it is legal to purchase for research purposes from licensed suppliers. It is your responsibility to ensure you comply with all applicable laws.
How should I store the ampules?
Store them at room temperature, away from direct sunlight and moisture. Keep them out of reach of children and animals.
Can I use this product for personal use?
No. This product is sold strictly for laboratory research and is not intended for human or veterinary consumption.
What is the difference between Masteron Propionate and Masteron Enanthate?
The main difference is the ester attached to the drostanolone molecule. Propionate is a shorter ester, meaning it is released faster and requires more frequent administration in research settings. Enanthate is a longer ester with a slower release profile.
