Aromasin Dosage Guide for Bodybuilders: How to Use Exemestane Safely and Effectively
🧠 What Is Aromasin (Exemestane)?
Aromasin, the brand name for Exemestane, is a Type I, steroidal aromatase inhibitor (AI). Originally developed to treat hormone-sensitive breast cancer, it has become a staple in bodybuilding circles for managing estrogen levels during and after anabolic steroid cycles.
Unlike reversible AIs like Arimidex or Letrozole, Aromasin permanently disables the aromatase enzyme. This means no estrogen rebound after discontinuation—a major benefit for athletes concerned about post-cycle estrogen spikes.
💪 Why Bodybuilders Use Aromasin
During anabolic cycles—especially with compounds like Testosterone, Dianabol, or Deca—the risk of excess estrogen is high. Elevated estrogen can lead to:
-
Gynecomastia (gyno)
-
Water retention and bloating
-
Fat gain
-
Libido suppression
-
Poor testosterone recovery
Aromasin (Exemestane) helps prevent these effects while also boosting natural testosterone—making it ideal for on-cycle support and PCT.
📏 Recommended Aromasin Dosage for Bodybuilders
💉 On-Cycle Dosage
| Cycle Type | Recommended Dose |
|---|---|
| Mild Cycle (Test ≤ 400 mg/wk) | 6.25–12.5 mg every other day |
| Moderate Cycle (Test 500–600 mg/wk) | 12.5 mg EOD or daily |
| Heavy Cycle (Test 750+ mg/wk or multiple aromatizing compounds) | 25 mg EOD or daily |
✅ Tip: Start low and increase only if estrogenic symptoms occur. Adjust based on bloodwork.
🔁 Post Cycle Therapy (PCT) Dosage
During PCT, Aromasin not only manages estrogen but also supports LH and FSH production to boost natural testosterone.
| Week | Suggested Aromasin Dose |
|---|---|
| Week 1 | 25 mg daily |
| Week 2 | 12.5 mg daily |
| Week 3 | 12.5 mg every other day |
| Week 4 | 6.25 mg every other day |
📌 Often paired with Nolvadex or Clomid for optimal recovery.
💊 TRT Support Dosage
For those on testosterone replacement therapy, keeping estrogen in check is vital for libido, mood, and heart health.
| TRT Dose | Aromasin Dose |
|---|---|
| Test ≤ 125 mg/week | 6.25 mg 1–2x per week |
| Test > 125 mg/week | 6.25–12.5 mg weekly |
⚠️ Always confirm need with estradiol-sensitive bloodwork. Target E2 range: 20–40 pg/mL.
⚠️ Aromasin Side Effects
While Aromasin is milder than Letrozole or Arimidex, over-suppression of estrogen can still cause issues, including:
-
Joint pain
-
Mood swings
-
Low libido
-
Dry skin
-
Fatigue
-
Cholesterol imbalance (lower HDL)
💡 Avoid crashing estrogen. If you feel stiff, tired, or “flat” in the gym—check your levels and lower your dose.
🧪 How to Monitor Effectiveness
To optimize Aromasin dosage:
-
Run bloodwork every 4–6 weeks
-
Test for estradiol (E2-sensitive), testosterone, and lipids
-
Adjust dosage based on how you feel and lab values—not guesswork
💬 FAQs About Aromasin Dosage
Q: Can I take Aromasin daily on-cycle?
Yes, but only if needed. Daily dosing (25 mg) is often reserved for high-dose or multi-compound cycles. For most, 12.5 mg EOD is sufficient.
Q: Should I taper off Aromasin?
Tapering is smart, especially post-cycle. It allows your body to normalize estrogen levels gradually and avoid rebound effects.
Q: Is Aromasin better than Arimidex?
Yes, for many. Aromasin is less harsh on cholesterol, stimulates testosterone, and causes no estrogen rebound—making it ideal for PCT and longer cycles.
Q: Can women use Aromasin for fat loss?
Only under medical supervision. While it may reduce estrogen-driven fat, it can negatively impact hormone balance and fertility in women.
🏁 Final Thoughts: Mastering Aromasin Dosage
Aromasin is one of the most versatile and bodybuilder-friendly aromatase inhibitors available. Whether you’re running a bulking cycle, cutting stack, or recovering post-cycle, the right dosage makes all the difference.
