Choosing between Clascoterone (CAS 19608-29-8) and Spironolactone for acne or hair loss often comes down to two factors: cost and convenience. While both target androgen-related skin and hair issues, their price tags, administration methods, and side effect profiles differ significantly. This guide breaks down the financial and clinical pros and cons of each—plus reveals how to access affordable, high-purity Clascoterone for research or experimental use.


Clascoterone vs. Spironolactone: Key Differences

1. Mechanism of Action

  • Clascoterone: A topical androgen receptor inhibitor (brand name Winlevi®). Blocks DHT locally in the skin/scalp, minimizing systemic side effects.
  • Spironolactone: An oral potassium-sparing diuretic with anti-androgen effects. Reduces DHT production but impacts the entire body.

2. FDA Approvals

  • Clascoterone: Approved for acne vulgaris (2020).
  • Spironolactone: Approved for hypertension and heart failure but used off-label for acne/hair loss.

3. Typical Use Cases

ConditionClascoteroneSpironolactone
Acne vulgaris✅ First-line✅ Off-label
Androgenetic alopecia✅ Emerging use✅ Common
Hormonal acne✅ Effective✅ Effective

Cost Comparison: Clascoterone vs. Spironolactone

Clascoterone Cream 1% (Winlevi®)

  • Retail price (without insurance): 500–500–800 per 60g tube (1-month supply).
  • With insurance/savings programs: 25–25–100/month.
  • Research-grade cost: 50–50–150/tube (≥98% purity, non-prescription).

Spironolactone (Oral Tablets)

  • Generic price (without insurance): 10–10–30/month for 50–100mg doses.
  • With insurance: As low as $4/month.

Annual Cost Breakdown (Uninsured):

  • Clascoterone: ~6,000–6,000–9,600.
  • Spironolactone: ~120–120–360.

Why Is Clascoterone More Expensive?

  1. Patent Status: Clascoterone’s patents (held by Cassiopea) won’t expire until 2030, blocking generics. Spironolactone has been generic since 1985.
  2. Administration Method: Topical formulations require complex stabilization, increasing production costs.
  3. Niche Application: As a first-in-class topical anti-androgen, it lacks competition.

How to Reduce Clascoterone Costs

1. Research Chemical Suppliers

For non-prescription use (e.g., lab studies or custom formulations), research-grade Clascoterone (CAS 19608-29-8) costs 80–90% less than Winlevi®. Ensure suppliers:

  • Provide third-party purity testing (HPLC/NMR reports).
  • Follow GMP guidelines for production.
  • Label products “Not for human use.”

KiloBio’s Clascoterone offers 99%+ pure Clascoterone at 50–50–150 per tube, ideal for researchers and compounding pharmacists.

2. Bulk Purchases

Order 3–6 month supplies to save 20–40%.

3. International Options

Generic versions (e.g., in India) cost 150–150–300/tube but carry quality risks.


Spironolactone’s Hidden Costs

While cheaper upfront, Spironolactone may incur long-term expenses:

  • Blood tests: Required to monitor potassium levels and kidney function (100–100–300/year).
  • Side effect management: Fatigue, dizziness, or menstrual irregularities may necessitate additional medications.
  • Time investment: Daily oral dosing vs. twice-daily topical application.

FAQs About Clascoterone vs. Spironolactone

1. Can I Use Clascoterone and Spironolactone Together?

Yes! Some dermatologists combine them for severe hormonal acne. Monitor for additive side effects like dryness.

2. Is Clascoterone Safer Than Spironolactone?

For most, yes. Clascoterone’s topical action avoids systemic risks (e.g., hyperkalemia).

3. Will Generic Clascoterone Ever Be Available?

Not until 2030. Until then, research-grade options offer cost relief.

4. How Can I Verify Clascoterone Quality?

Request a Certificate of Analysis (COA) with HPLC results—KiloBio provides these upfront.


Final Verdict

While Spironolactone wins on upfront cost, Clascoterone offers superior convenience and safety—if you can access it affordably. For researchers and cost-conscious users, KiloBio’s Clascoterone bridges the gap, providing lab-grade quality at a fraction of the retail price.
