How to Run a Lean Bulk Cycle Without Gaining Fat – Steroid Guide 2025
Bulking doesn’t have to mean stuffing yourself with food and accepting layers of unwanted fat. In 2025, smarter athletes are turning to lean bulking steroid cycles to build dry, quality muscle mass while staying relatively shredded year-round.
In this guide, we’ll break down exactly how to bulk cleanly with steroids, what compounds to use, diet strategies, and how to keep fat gain minimal.
🍽️ What Is a Lean Bulk?
A lean bulk is a controlled muscle-gaining phase where:
- Caloric surplus is small (+250 to +500 kcal/day)
- Emphasis is placed on macronutrient precision
- Water and fat gain are tightly managed
- Steroids are selected for dry or hard muscle gains
The goal: maximize muscle, minimize fat.
💉 Best Steroids for Lean Bulking
1. Testosterone Enanthate or Cypionate
- Dose: 300–500mg/week
- Why: A strong foundation for any bulking cycle. Builds size, supports recovery.
2. Equipoise (Boldenone Undecylenate)
- Dose: 300–600mg/week
- Why: Promotes steady lean gains, improves appetite, low estrogenic activity.
3. Primobolan (Methenolone Enanthate)
- Dose: 400–600mg/week
- Why: Great for lean mass, keeps you hard and vascular, minimal water retention.
4. Turinabol (Tbol)
- Dose: 30–50mg/day (4–6 weeks)
- Why: Mild oral with dry gains, doesn’t aromatize, pairs well with Test.
Optional Additions:
- Masteron for hardness
- Anavar for strength and dry tissue
- Arimidex/Letrozole to control estrogen during bulk
🔄 Sample Lean Bulk Cycle (12 Weeks)
| Week | Testosterone E | Equipoise | Tbol (optional) | AI (Arimidex) |
|---|---|---|---|---|
| 1–12 | 400mg/week | 400mg/week | – | 0.5mg EOD |
| 1–6 | – | – | 40mg/day |
Note: Always follow with proper PCT (e.g., Clomid + Nolvadex) post-cycle.
🥩 Lean Bulking Diet Tips
- Eat at a surplus of 10–15% above maintenance calories
- Focus on high-quality protein (1–1.2g per pound of bodyweight)
- Choose clean carbs: rice, potatoes, oats, fruits
- Healthy fats: avocado, olive oil, nuts
- Avoid dirty bulking foods like fast food, sugar, and excessive dairy
Meal frequency: 4–5 meals/day to maintain steady nutrient flow
🧬 Supplements for Clean Gains
- Creatine Monohydrate – Strength and cell volumization
- Digestive enzymes – Improve nutrient absorption
- Liver support (TUDCA, NAC) – Especially if using orals
- Omega-3s – Inflammation control
- Vitamin D + Zinc – Testosterone support
🚫 Mistakes That Ruin Lean Bulks
- Eating like it’s a dirty bulk
- Using bloating compounds like Dbol or Deca
- Skipping cardio (yes, cardio while bulking is key!)
- Poor estrogen management
- Not monitoring weight gain (aim for 1–2 lbs/week)
🔍 Lean Bulk FAQs
Q: Can I gain muscle without gaining fat?
A: Minor fat gain is normal, but with the right stack and clean diet, it can be kept very low.
Q: Should I do cardio while bulking?
A: Yes—3x/week helps improve appetite, recovery, and insulin sensitivity.
Q: What if I’m a hardgainer?
A: Use Test + EQ + Tbol, and slightly increase your surplus (+500 kcal/day). Prioritize rest and sleep.
