High-Quality STROMUSC Dianabol(Metandienone)50mg/ml For Bodybuilding CAS:72-63-9
Metandienone—known to most as Dianabol, or simply "Dbol"—occupies a singular place in the history of performance enhancement. Developed in the 1950s by Dr. John Bosley Ziegler in collaboration with Ciba Pharmaceuticals, it emerged from a specific pursuit: to create a compound that retained testosterone's anabolic muscle-building properties while minimizing its androgenic (masculinizing) side effects. Ziegler's work was partly inspired by observations of Soviet weightlifters at the 1954 World Championships, who appeared to be using testosterone derivatives to gain a competitive edge.
The Compound That Defined an Era
Metandienone-known to most as Dianabol, or simply "Dbol"-occupies a singular place in the history of performance enhancement. Developed in the 1950s by Dr. John Bosley Ziegler in collaboration with Ciba Pharmaceuticals, it emerged from a specific pursuit: to create a compound that retained testosterone's anabolic muscle-building properties while minimizing its androgenic (masculinizing) side effects. Ziegler's work was partly inspired by observations of Soviet weightlifters at the 1954 World Championships, who appeared to be using testosterone derivatives to gain a competitive edge.
What Ziegler and his team synthesized was a C1-C2 dehydrogenated derivative of methyltestosterone, a 17α-alkylated anabolic-androgenic steroid that could be taken orally with high bioavailability. The compound was commercially released in 1958 and quickly became the gold standard for bulking. Within years, Ziegler was supplying it to the US Olympic weightlifting team at the 1960 Rome Olympics.
The 50mg/mL liquid oral formulation represents a modern evolution of this legendary compound-a concentrated, precisely dosed preparation favored by advanced users who prefer liquid administration over tablets for more flexible dosing and potentially faster absorption. MATS (a designation indicating pharmaceutical-grade manufacturing standards) signifies a level of quality control that distinguishes it from black-market alternatives of dubious purity.
Chemical Identity and Structural Distinctions
Chemically, Metandienone is designated as 17β-hydroxy-17α-methylandrosta-1,4-dien-3-one. Its molecular formula is C₂₀H₂₈O₂ with a molecular weight of 300.4 g/mol. The compound is known by multiple synonyms: methandrostenolone, dehydromethyltestosterone, methandienone, and various trade names including Averbol, Danabol, Metanabol, and Naposim.
Two structural features define its pharmacological profile:
The Δ1 double bond (the C1-C2 dehydrogenation) distinguishes it from methyltestosterone and confers a more favorable anabolic-to-androgenic ratio-approximately 2-3:1 compared to testosterone's 1:1. This modification enhances receptor binding affinity while reducing the compound's propensity for androgenic side effects.
The 17α-methyl group is the defining feature that enables oral administration. This alkylation protects the molecule from rapid first-pass hepatic metabolism, allowing it to survive digestion and enter systemic circulation. However, this same modification is responsible for the compound's well-documented hepatotoxicity, as it places sustained metabolic stress on the liver.
The compound is an androgen receptor agonist, meaning it binds directly to androgen receptors in muscle tissue and bone. Interestingly, research has shown that while Metandienone is a relatively low-affinity ligand for the androgen receptor in vitro, it functions as a potent activator in cell-based assays-suggesting that its efficacy stems not from receptor binding strength alone but from downstream signaling events.
Mechanism of Action: Beyond Simple Receptor Binding
The pharmacology of Metandienone operates through multiple interconnected pathways:
Androgen Receptor Activation: Upon ingestion, the compound is metabolized in the liver and binds to androgen receptors in skeletal muscle. This binding triggers a cascade of transcriptional events that upregulate protein synthesis and enhance nitrogen retention-creating the anabolic environment necessary for muscle hypertrophy.
Enhanced Glycogenolysis: Metandienone increases the breakdown of glycogen into glucose, providing immediate energy for muscle contractions during intense training. This explains the rapid strength gains users report within the first week-the muscles are simply better fuelled.
Increased Red Blood Cell Production: The compound stimulates erythropoiesis, increasing red blood cell count and improving oxygen delivery to muscle tissues. This enhances endurance, delays fatigue, and accelerates recovery between workouts.
Cortisol Suppression: A single 10mg dose of Dianabol has been shown to reduce endogenous cortisol by 50-70%. Cortisol is a catabolic hormone that breaks down muscle tissue; its suppression creates a more favorable anabolic environment.
Muscle Regeneration vs. Hypertrophy: A 2019 study published in ScienceDirect revealed an intriguing nuance: Metandienone treatment induces skeletal muscle regeneration rather than单纯 hypertrophy, and activates endocrine negative feedback. This suggests that some of the "gains" may represent repair and rebuilding of existing muscle fibers rather than the creation of new tissue-a distinction with implications for how gains are maintained post-cycle.
Applications in Bodybuilding
The primary application of Dianabol in bodybuilding is massive, rapid bulking. It is typically employed during the off-season when the goal is to add as much muscle tissue as possible, accepting some water retention as an inevitable trade-off.
Kickstarting Cycles: One of the most common applications is using Dianabol as an "oral kickstart" at the beginning of a longer injectable cycle. While long-acting injectables like testosterone enanthate or cypionate take several weeks to reach peak blood levels, Dianabol's rapid onset provides immediate anabolic effects from day one.
Standalone Use: Some novices use Dianabol alone, though this is widely considered suboptimal. The rapid onset of gains is seductive, but Dianabol-only cycles are difficult to sustain beyond 4-6 weeks due to liver toxicity, and much of the mass gained is water weight that dissipates upon cessation.
Stacking: More advanced protocols stack Dianabol with injectable testosterone (to maintain a baseline of androgenicity) and sometimes with nandrolone (Deca-Durabolin) for synergistic mass-building effects.
Documented Benefits
The benefits of Dianabol are among the most well-documented in the anabolic steroid literature:
Rapid Muscle Accretion: Users typically report visible changes within the first week and significant mass gains over a 4-6 week cycle. One study found significant increases in weight and body potassium with Methandrostenolone compared to placebo, confirming its anabolic effect.
Strength Gains: Research has demonstrated that Dianabol supplementation increases strength in healthy males engaged in strenuous weight training beyond what training alone achieves. The strength increases are often dramatic and rapid.
Improved Nitrogen Balance: The compound creates a positive nitrogen balance-meaning the body retains more nitrogen than it excretes, a prerequisite for muscle protein synthesis.
Enhanced Recovery: By increasing red blood cell count and reducing cortisol, Dianabol accelerates recovery between training sessions, allowing for higher training frequency and volume.
Performance in Clinical Contexts: Beyond bodybuilding, Dianabol was originally found to reverse osteoporosis in elderly patients and promote skin growth in burns victims-testament to its genuine anabolic properties.
Dosage Protocols for the 50mg/mL Formulation
The 50mg/mL concentration is a high-potency preparation intended for experienced users. Dosage must be calibrated carefully:
Beginner (first-time users): 10-20mg per day, typically divided into two doses. A 50mg/mL solution makes this easy-0.2-0.4mL daily.
Intermediate: 20-30mg per day, divided into two to three doses to maintain stable blood levels. This equates to 0.4-0.6mL daily.
Advanced: Up to 50mg per day, though this significantly increases the risk of adverse effects. At this dose, the full 1mL would be consumed daily, typically split across three administrations.
Administration Tips: The liquid should be taken with food to enhance absorption and reduce gastric irritation. Doses should be spaced evenly throughout the day-every 4-6 hours is optimal given the compound's short half-life. Staying well-hydrated and maintaining a nutrient-dense diet are critical during the cycle.
Cycle Duration and Structure
The standard Dianabol cycle runs 4 to 6 weeks. Extending beyond this window is strongly discouraged due to hepatotoxicity.
Typical 6-Week Cycle:
●Weeks 1-4: Dianabol at 20-30mg daily (0.4-0.6mL of the 50mg/mL solution)
●Weeks 1-10: Testosterone enanthate or cypionate at 400-500mg weekly (injected)
●Weeks 5-6: Dianabol tapered or discontinued; testosterone continues
This structure uses Dianabol as a "kickstart" while the longer-acting testosterone builds to steady-state levels.
Dianabol-Only Cycle (not recommended for serious users):
●4-6 weeks at 20-30mg daily
●Followed immediately by PCT
The short duration of Dianabol-only cycles means gains are primarily water and glycogen-rapidly lost post-cycle unless consolidated with other compounds.
Half-Life and Dosing Frequency
The elimination half-life of Dianabol is 3 to 6 hours. This exceptionally short half-life has profound implications for dosing strategy:
●Blood levels fluctuate dramatically throughout the day if doses are not spaced properly
●To maintain stable anabolic levels, the daily dose should be divided into two or three administrations
●The compound should be taken with or immediately before meals to minimize the "peak-and-trough" effect
●Some users take their final dose before training to maximize acute strength benefits
The short half-life also means that Dianabol clears the system relatively quickly upon cessation-an advantage for those concerned about detection windows, but a disadvantage for maintaining stable anabolic signaling.
Post-Cycle Therapy (PCT)
PCT is non-negotiable after any Dianabol cycle. The compound suppresses endogenous testosterone production through negative feedback on the hypothalamic-pituitary-gonadal axis. Without proper PCT, natural testosterone may remain suppressed for weeks or months, leading to loss of gains, mood disturbances, and potential long-term endocrine dysfunction.
When to Start PCT: For Dianabol-only cycles, PCT should begin the day after the last dose, given the compound's short half-life. For stacked cycles with injectable testosterone, PCT typically begins 2 weeks after the last injection of long-acting esters.
Standard PCT Protocol (4 weeks):
| Weeks | Clomid (Clomiphene) | Nolvadex (Tamoxifen) |
|---|---|---|
| 1-2 | 100mg daily | 40mg daily |
| 3-4 | 50mg daily | 20mg daily |
Alternative Protocol:
●Clomid: 50mg daily for 4 weeks
●Nolvadex: 20mg daily for 4 weeks
HCG Option: Some protocols include Human Chorionic Gonadotropin (HCG) at 250-500 IU every other day during the first 1-2 weeks of PCT to stimulate Leydig cell function.
Monitoring: Blood work is strongly recommended before, during, and after PCT to confirm that testosterone, LH, FSH, and liver enzymes have returned to baseline.

Conclusion: A Legacy Compound, Modern Formulation
Top-Quality Dianabol 50mg/mL represents the convergence of a legendary compound and modern pharmaceutical precision. Its rapid anabolic effects, documented strength gains, and historical significance make it a cornerstone of bulking protocols. However, its short half-life demands disciplined dosing, its hepatotoxicity limits cycle duration, and its suppression of natural testosterone necessitates rigorous PCT.
For the informed user who respects both the power and the peril of this compound, Dianabol remains one of the most effective mass-building tools available. The 50mg/mL liquid formulation offers precise dosing flexibility, but with that precision comes the responsibility of equally precise cycle management, liver support, and post-cycle recovery.
