Methyl‑testosterone

(also called 17α‑methyl‑androst-4-en‑3β‑ol, C₁₉H₂₆O₂)




Nandrolone (nandrolone decanoate) – the most commonly prescribed nandrolone ester; the parent drug is 2‑dehydronandrolone (nandrolone). The decanoate ester is what gives it a long‑acting profile.

1️⃣ How These Steroids Work



Property Methyl‑testosterone Nandrolone


Core structure 19‑carbon, saturated A‑ring (no Δ¹) 19‑carbon, unsaturated A‑ring (Δ²)


Key functional groups 17β‑OH (active), 3‑ketone, no double bonds 17β‑OH (active), 3‑ketone, Δ² double bond


Receptor interaction Binds androgen receptor → ↑ protein synthesis, muscle anabolism, bone formation Similar, but Δ² reduces susceptibility to aromatase and 5α‑reductase


Metabolic pathways Aromatized to estrogen (via CYP19), reduced by 5α‑reductase to dihydrotestosterone‑like metabolites Less aromatization → lower estrogenic side effects; less reduction to potent DHT

4. Comparative Table: Efficacy, Side‑Effects & Practical Use



Drug Dose (Daily) Primary Benefit Common Adverse Effects Special Considerations


Methandrostenolone (Dianabol) 20–25 mg (oral) Rapid ↑ lean body mass; high anabolic:catabolic ratio. Gynecomastia, water retention, hypertension, hepatotoxicity (oral). Avoid in patients with liver disease; monitor BP & liver enzymes.


Sustanon‑1 100 mg IM q2–3 wk (or 50 mg q week) Sustained testosterone effect; less estrogenic. Mild edema, acne, mood swings. Use only under physician supervision.


Testosterone cypionate 200 mg IM q1–2 wk Provides steady hormone levels. Same as above plus potential gynecomastia if aromatized. Monitor serum testosterone & estrogen.


Methandrostenolone (Dianabol) 20 mg PO daily Rapid muscle gains, high risk of liver toxicity. Hepatic damage, gynecomastia, water retention. Avoid; only in supervised settings.


Key points:





The "best" anabolic agent depends on individual goals, experience level, tolerance for side‑effects, and health status.


In general, clandestine testosterone or its analogues (e.g., stanozolol) are favored by bodybuilders due to predictable efficacy and manageable side‑effects when used properly.


For athletes prioritizing performance speed and strength, steroid derivatives with high anabolic:androgenic ratios such as oxymetholone or trenbolone are often chosen, despite higher toxicity.


Those looking for long‑term conditioning without excessive estrogenic effects may prefer stanozolol (Austrian) or nandrolone (Nand).


Ethyltestosterone, with its unique pharmacodynamics, is rarely used but can be an option in specialized protocols where a potent anabolic effect and low androgenic side‑effects are desired.







4. Practical Guidance for Selecting the Right Compound



Goal Recommended Compounds Key Considerations


Maximize protein synthesis & muscle mass Ethyltestosterone, Testosterone enanthate, Nandrolone decanoate Use with a balanced diet and resistance training; watch for estrogenic side‑effects.


Minimal androgenic side‑effects (e.g., acne, hair loss) Ethyltestosterone (low androgenicity), Estradiol (if you need estrogen) Pair with aromatase inhibitors if estrogen spikes occur.


Enhance endurance & recovery Testosterone enanthate, Nandrolone decanoate Lower doses over longer periods can help maintain muscle quality without dramatic growth spurts.


Rapid increase in lean body mass Testosterone enanthate (high dose) Combine with anabolic steroids if necessary; be prepared for significant water retention and potential liver stress.

How to Use This Information




Set a Goal:


- Muscle Gain: Focus on testosterone enanthate or nandrolone decanoate at higher doses, paired with adequate protein intake (1–2 g/kg/day) and progressive resistance training.

- Strength & Endurance: Lower-dose testosterone may suffice; consider adding creatine monohydrate (5 g/day) to boost power output.





Track Your Intake:


- Use a food diary or an app that records macro‑nutrients. Ensure your protein, carb, and fat ratios align with your training phase: higher carbs for heavy lifts, moderate carbs for endurance sessions.



Adjust According to Feedback:


- If you’re not seeing the desired gains, reassess caloric surplus/deficit. A 250 kcal deficit can still allow muscle gain if protein is adequate and training intensity is high.



Stay Hydrated & Rested:


- Adequate water intake supports metabolic processes. Sleep 7–9 hours nightly to aid recovery and hormonal balance.





Quick Reference Cheat Sheet



Component Target Notes


Protein 1.6‑2.0 g/kg body weight Spread over meals; aim for 20‑40 g per serving


Calories Slight surplus (≈250 kcal) or maintenance if on deficit schedule Adjust based on weekly weigh‑in


Carbohydrates 3‑5 g/kg body weight Focus on complex sources pre‑/post‑workout


Fats 0.8‑1.0 g/kg body weight Emphasize unsaturated fats


Hydration ≥3 L/day (increasing with sweat loss) Use electrolytes if sweating >2 h
