Join us as we put Turinabol and Masteron side by side to unveil which compound truly deserves the title of champion for muscle gains and athletic excellence.
Understanding Anabolic Steroids: What They Are and How They Work
Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are synthetic derivatives of testosterone, the primary male sex hormone. These compounds are designed to mimic the physiological effects of testosterone, promoting muscle growth and enhancing athletic performance.
They function by binding to androgen receptors in muscle cells, which initiates protein synthesis—the biological process of building new muscle tissue. This results in:
Increased muscle mass
Enhanced strength and power
Reduced muscle recovery time, allowing more frequent and intense training sessions
“Anabolic steroids stimulate muscle growth by enhancing nitrogen retention and increasing the rate of muscle protein synthesis.” — Bhasin, JAMA
The development of anabolic steroids began in the mid-20th century for medical applications, including treating muscle-wasting diseases and delayed puberty. However, the athletic potential of these compounds quickly led to their adoption by bodybuilders, weightlifters, and competitive athletes across various sports.
“Anabolic steroid use became widespread in sports during the 1960s and 1970s, leading to long-term controversies regarding ethics, health, and regulation.” — Yesalis, Journal of Athletic Training
While anabolic steroids offer measurable benefits for physique and performance, they are also associated with a range of potential side effects—from acne and mood swings to cardiovascular strain and hormonal imbalance.
Turinabol: Composition, Benefits, and Usage
What Is Turinabol?
Turinabol, chemically known as Chlorodehydromethyltestosterone, is a C-17 alpha-alkylated oral anabolic steroid developed in the 1960s by East German scientists. It was created as part of the German Democratic Republic’s state-sponsored doping program and was used extensively to enhance the performance of elite athletes.
Turinabol is structurally derived from Dianabol (Methandrostenolone), with the addition of a chlorine atom at the fourth carbon position. This modification significantly reduces its androgenic effects while preserving its anabolic potency, making it a favored choice for both male and female athletes.
“Turinabol offered significant performance gains without the water retention and estrogenic side effects typically seen with other steroids.” — Franke, Clinical Chemistry
Key Benefits of Turinabol
Turinabol’s appeal lies in its dry, clean gains—making it ideal for cutting or recomposition cycles. The compound delivers a balance of muscle growth and strength improvements without bloating.
Promotes lean muscle mass without excessive water retention
Improves strength and muscle density
Enhances endurance and stamina, particularly useful for runners, swimmers, and cyclists
Low estrogenic activity, reducing risk of gynecomastia or fat gain
Mild anabolic profile, which may result in fewer side effects at conservative dosages
“Turinabol allows for quality muscle accrual while avoiding the estrogenic complications common with other oral steroids.” — Hartgens, Sports Medicine
Turinabol Dosage and Cycle Length
Typical dosage: 20–50 mg per day
Cycle duration: 6 to 8 weeks
Stacking: Commonly stacked with non-aromatizing agents such as Anavar or Masteron
Though considered milder than compounds like Dianabol or Anadrol, Turinabol is still hepatotoxic due to its C-17 alkylation and should be used with proper liver support.
“Despite lower androgenicity, Turinabol remains liver toxic and can elevate liver enzymes when used at high doses or extended durations.” — Nieschlag, Endocrine Reviews
Masteron: Composition, Benefits, and Usage
What Is Masteron?
Masteron, chemically known as Drostanolone, is an injectable DHT-derived anabolic steroid (dihydrotestosterone). First developed in the 1950s, it was initially prescribed for breast cancer treatment due to its strong anti-estrogenic properties. However, its unique combination of androgenic potency and physique-enhancing effects quickly gained it popularity among competitive bodybuilders and athletes.
Masteron is available in two primary esterified forms:
Drostanolone Propionate – fast-acting, with more frequent injections
Drostanolone Enanthate – longer-acting, requiring fewer injections per week
“Masteron’s anti-estrogenic effect made it a useful agent in treating hormone-sensitive cancers, but its cosmetic outcomes drew interest from the athletic community.” — Kochakian, Steroids
Key Benefits of Masteron
Masteron is highly valued for creating a dry, hard, and vascular physique, especially during cutting cycles or pre-contest preparation. Unlike aromatizing compounds, Masteron does not convert to estrogen, eliminating common estrogen-related side effects.
Primary benefits include:
Increased muscle hardness and density
Enhanced vascularity and definition
No aromatization, meaning zero water retention or gynecomastia risk
Synergistic effect when stacked with other compounds
Visibly shredded appearance, making it a go-to for stage-ready conditioning
“Because Drostanolone does not aromatize, it can reduce estrogenic effects in a stack while amplifying androgenic physique traits.” — Wilson, Journal of Strength and Conditioning Research
Masteron Dosage and Cycle Length
Dosage: 200–400 mg per week
Cycle length: 8–12 weeks
Administration: Intramuscular injection, typically 2–3 times per week depending on ester
Due to its strong androgenic nature, Masteron may not be ideal for beginners or female users, unless administered under professional supervision.
“Drostanolone is particularly useful in cutting cycles, but its androgenic side effects must be respected and managed with care.” — Hartgens & Kuipers, Human Psychopharmacology

Masteron P
100 mg
Every other day (IM)
Supportive
NAC or TUDCA
Daily (liver support)
AI (optional)
Arimistane or similar
If estrogen is a concern from other compounds used in stack
Note: This stack is best suited for cutting or recomposition. For bulking, other agents like testosterone or nandrolone may be added with careful planning and estrogen control.
Key Considerations:
Run for 6–8 weeks for oral-based stacks; longer durations may increase liver stress.
Include on-cycle support supplements (e.g., liver protectants and lipid stabilizers).
Conduct regular blood work to monitor liver enzymes, lipids, and hormone levels.
Never skip Post-Cycle Therapy (PCT)—testosterone suppression is still a concern.
Additional Stack Options
Turinabol + Masteron + Testosterone (TRT base):
This stack is popular among advanced users seeking to maintain physiological testosterone levels while maximizing muscle preservation and physique enhancement.
Turinabol + Masteron + Anavar:
A triple oral/IM cutting stack that offers:
Dry, hard gains
Minimal water retention
Enhanced strength without bulk
“Multi-compound cutting stacks are designed to amplify cosmetic outcomes while maintaining lean tissue under caloric restriction.” — Hartgens & Kuipers, Sports Medicine
Post-Cycle Therapy (PCT) After a Turinabol and Masteron Cycle
Whether mild or moderate, any steroid cycle that suppresses natural testosterone requires a proper Post-Cycle Therapy (PCT) to restore hormonal balance, protect health, and preserve muscle gains.
Why PCT Is Essential
Turinabol and Masteron—despite being non-aromatizing—still suppress endogenous testosterone production. Without recovery support, users may experience:
Fatigue
Decreased libido and erectile dysfunction
Mood swings or depression
Increased body fat and muscle loss
“The hypothalamic-pituitary-gonadal (HPG) axis is highly sensitive to exogenous androgens. Even mild steroids can reduce LH and FSH to near zero, halting testosterone production.” — Basaria, New England Journal of Medicine
PCT Goals
Restart natural testosterone production
Normalize estrogen and androgen levels
Prevent hormonal crashes
Preserve muscle mass and performance outcomes
Support liver and cardiovascular function
