Classification
10 x Pharmaqo Mastabol P 100mg x 10ml is a bulk presentation marketed as an injectable drostanolone propionate product, commonly associated with the name Mastabol P or Masteron P. Drostanolone is an anabolic-androgenic steroid (AAS) and is a derivative of dihydrotestosterone (DHT). The stated presentation contains 10 individual 10ml vials, with each vial labeled at 100mg/ml, giving a stated total volume of 100ml across the complete bulk quantity.
Because products marketed under bodybuilding-oriented names can vary by manufacturer and regulatory status, the exact active ingredient, concentration, and authorization should always be verified from the original product packaging.

What Is 10 x Pharmaqo Mastabol P 100mg x 10ml?
10 x Pharmaqo Mastabol P 100mg x 10ml describes a bulk presentation containing 10 separate 10ml vials of a product marketed as drostanolone propionate. Each vial is labeled at 100mg/ml, resulting in a stated total volume of 100ml.
Drostanolone is a synthetic anabolic-androgenic steroid structurally related to DHT. It interacts with androgen receptors and produces both anabolic and androgenic effects. The propionate ester influences the release characteristics of the active hormone following administration.
The “10 x” designation indicates that this is a bulk multi-vial presentation, rather than a single 10ml vial.
Dosage
The 100mg/ml specification identifies the product concentration and should not be interpreted as a recommended personal dose. Drostanolone propionate is not an appropriate medication for self-directed bodybuilding cycles, and a safe regimen cannot be determined from the vial strength alone.
Where an anabolic steroid is legitimately prescribed, dosing depends on the specific authorized product, medical indication, patient characteristics, and clinical monitoring.
Important considerations include:
- Use only under appropriate medical supervision.
- Do not independently increase injection amounts or frequency.
- Verify the active ingredient and concentration before administration.
- Discuss existing cardiovascular, liver, and reproductive conditions with a healthcare professional.
- Avoid combining multiple anabolic steroids without professional guidance.
How Does 10 x Pharmaqo Mastabol P 100mg x 10ml Work?
Drostanolone acts primarily by binding to androgen receptors. Activation of these receptors can influence gene expression and protein metabolism in androgen-responsive tissues.
Its effects may influence muscle tissue, skin, hair, reproductive function, and other androgen-sensitive systems. Because drostanolone is derived from DHT, its activity is predominantly androgenic and anabolic.
The propionate ester affects how the hormone is released after administration, while the active drostanolone interacts with androgen receptors to produce its physiological effects.
Benefits
Drostanolone is primarily known for its anabolic-androgenic activity rather than as a routinely used modern medical treatment. Any legitimate therapeutic application depends on the exact formulation, jurisdiction, and clinical circumstances.
Potential pharmacological effects associated with androgenic-anabolic activity include:
- Influencing protein metabolism.
- Supporting anabolic activity in androgen-responsive tissues.
- Affecting nitrogen and tissue metabolism.
- Producing androgen-dependent physiological effects.
Drostanolone is also heavily associated with bodybuilding and physique-enhancement markets. Claims about muscle definition, hardness, or competitive performance should not be presented as established medical benefits, and non-medical anabolic-steroid use carries significant health risks.
When Should You Take 10 x Pharmaqo Mastabol P 100mg x 10ml?
An injectable drostanolone product should not be self-administered based solely on its labeled concentration. The appropriate use of any authorized anabolic steroid depends on a legitimate medical indication and professional assessment.
The propionate ester generally has a shorter duration of action than some longer-acting steroid esters, but this does not establish a safe injection schedule for individual users.
Anyone considering anabolic-steroid treatment should first discuss hormone status, cardiovascular health, liver function, reproductive goals, and other relevant factors with a qualified healthcare professional.
When Should You Not Take 10 x Pharmaqo Mastabol P 100mg x 10ml?
Drostanolone may be inappropriate for individuals with certain medical conditions. Particular caution is warranted for people with:
- Prostate or male breast cancer.
- Significant cardiovascular disease.
- Uncontrolled high blood pressure.
- Liver or kidney disease.
- Abnormal cholesterol.
- A history of blood-clotting problems.
- Significant reproductive or fertility concerns.
- Pregnancy or potential pregnancy.
Women require particular caution because androgenic steroids can cause virilization, including voice deepening, increased facial or body hair, menstrual changes, and other potentially irreversible effects.
What Is the Mechanism of 10 x Pharmaqo Mastabol P 100mg x 10ml?
Drostanolone is an androgen-receptor agonist. It enters androgen-responsive tissues and binds to androgen receptors, influencing androgen-dependent gene expression.
Its basic mechanism can be represented as:
Drostanolone → androgen-receptor activation → altered gene expression → anabolic and androgenic physiological effects
Drostanolone is structurally related to DHT and is not aromatized into estrogen in the same manner as testosterone. However, this does not mean it is free from endocrine effects. Exogenous anabolic steroids can suppress normal reproductive hormone signaling and affect natural testosterone production.
Uses of 10 x Pharmaqo Mastabol P 100mg x 10ml
Drostanolone was historically associated with certain medical uses, including treatment of advanced breast cancer, but it is not a commonly used modern first-line treatment for breast cancer and availability and approved indications vary by jurisdiction.
The marketed product should not automatically be represented as an FDA-approved human medicine.
It should not be promoted as an approved treatment for:
- Bodybuilding.
- Athletic performance enhancement.
- Muscle definition.
- Fat loss.
- Cosmetic physique enhancement.
- Anti-aging.
- General testosterone optimization.
Any legitimate medical use should be based on an established indication and the specific authorized product’s labeling.
Warnings and Precautions for 10 x Pharmaqo Mastabol P 100mg x 10ml
Anabolic-androgenic steroids can affect the cardiovascular, endocrine, reproductive, hepatic, and metabolic systems.
Important concerns include:
- Suppression of natural testosterone production.
- Reduced sperm production.
- Changes in cholesterol.
- Increased blood pressure.
- Increased hematocrit.
- Acne and oily skin.
- Hair loss in genetically susceptible individuals.
- Mood or behavioral changes.
- Prostate-related effects.
Women may develop significant virilizing effects, some of which may not completely reverse after discontinuation.
People with cardiovascular, liver, prostate, or fertility concerns should receive appropriate medical evaluation before considering androgenic steroid exposure.
