Mastabol 100 British Dragon UK 100mg 10ml Masteron

Manufacturer: British Dragon, Thailand
Pack: 10 ml vial (100 mg/ml)

Pharmaceutical Name: Drostanolone Propionate

British Dragon Mastabol 100 is used by people interested in adding muscle hardness and density to their physiques, nearly always for the purpose of bodybuilding competitions.

Reduces Estrogen from other steroids
Masteron, being 5-alpha reduced, cannot form estrogen upon interaction with the aromatase enzyme yet still shows a very high affinity for it. Because it takes up so much of the aromatase enzyme, yet is refrained from actually using it by its structural make-up, it reduces the amount of estrogen formed from other steroids.

Masteron is derived from dihydrotestosterone (DHT) The DHT backbone has been modified with a 2-Methyl group to increase it’s anabolic properties making Masteron more effective at promoting the growth of muscle tissue than it’s non methylated parent.

Drostanolone propionate is described in product literature as “a steroid with powerful anabolic and anti-estrogenic properties” and indeed British Dragon Mastabol shares both properties. I personally call it “Liquid Proviron” as it shares similar properties to proviron, and also increases my libido!

British Dragon Mastabol 100 is most often used by my customers who are dieting bodybuilders and also by people who are into cardio, football and speed sports, it can increase muscle hardness and density, giving an individual a more complete appearance when competing on stage and is favoured for it’s ability to produce solid increases in lean muscle mass and strength which are normally accompanied by reductions in body fat level with minimal side effects. If you have not tried Masteron give it a go, it’s one I personally use myself.


Masteron 100 is usually injected 2 – 3 times per week. The typical weekly dosage is between 200 – 400mg, which is taken for 6 – 12 weeks. This level of use is sufficient to provide excellent gains in lean muscle mass and strength.

British Dragon Mastabol is often combined with other British Dragon steroids for an enhanced effect. Common stacks include British Dragon Decabol or British Dragon Boldabol (Equipoise) which can provide notably enhanced muscle gains without excess water retention. For mass gains it is often combined with British Dragon Testabol, the result can be solid muscle gain, with a lower level of water retention and lower estrogenic side effects than if these steroids were used alone. British Dragon Mastabol however is most commonly used by my customers combined with other non-aromatisable steroids such as British Dragon Mastabol, British Dragon Primbol which can greatly aid muscle retention and fat loss during a period that can be extremely catabolic without steroids
