Introduction
If you’re researching testosterone-boosting therapies, you’ve likely encountered trans-Clomiphene and Enclomifene—two closely related selective estrogen receptor modulators (SERMs) with overlapping applications in hormone optimization, fertility, and post-cycle therapy (PCT). But which one works faster? And where can you safely purchase high-quality versions of these compounds?
This guide answers:
- Key differences between trans-Clomiphene and Enclomifene
- Which one elevates testosterone levels faster
- How to avoid low-quality or mislabeled products
- Where to buy authentic trans-Clomiphene and Enclomifene
By the end, you’ll know exactly which compound aligns with your goals and how to source it safely.
What Are trans-Clomiphene and Enclomifene?
trans-Clomiphene (Zu-Clomiphene)
- Chemical Structure: The trans-isomer of Clomiphene citrate (CAS 15690-57-0).
- Primary Use: Stimulates gonadotropin release (LH/FSH) to boost testosterone and sperm production.
- Key Benefit: Faster onset of action compared to cis-Clomiphene.
Enclomifene (Enclomiphene Citrate)
- Chemical Structure: A purified form of trans-Clomiphene, often standardized for consistency.
- Primary Use: FDA-approved for male hypogonadism and off-label PCT.
- Key Benefit: Higher bioavailability and fewer estrogenic side effects.
Note: Both compounds work by blocking estrogen receptors in the pituitary gland, triggering increased LH/FSH secretion and subsequent testosterone production.
trans-Clomiphene vs. Enclomifene: Effectiveness Compared
1. Speed of Testosterone Increase
- trans-Clomiphene: Studies show testosterone levels rise within 7–14 days of use.
- Enclomifene: Clinical trials report significant testosterone elevation in 5–10 days due to optimized absorption.
Winner: Enclomifene acts slightly faster due to its refined formulation.
2. Estrogenic Side Effects
- trans-Clomiphene: May cause mild estrogenic activity (bloating, mood swings) in 10–15% of users.
- Enclomifene: Engineered to minimize estrogen receptor binding, reducing side effects to <5%.
Winner: Enclomifene is safer for long-term use.
3. Cost and Availability
- trans-Clomiphene: Often cheaper but harder to find in pure form.
- Enclomifene: More expensive due to pharmaceutical-grade standardization.
Winner: trans-Clomiphene wins on cost, but Enclomifene offers reliability.
Where to Buy trans-Clomiphene and Enclomifene Safely
The market is flooded with mislabeled or impure products. Here’s how to avoid scams:
1. Verify Third-Party Testing
- Demand Certificates of Analysis (CoA) confirming:
- Purity (≥98% for Enclomifene)
- Isomer Profile (trans-Clomiphene should be >99% pure)
2. Check CAS Numbers
- trans-Clomiphene: CAS 15690-57-0
- Enclomifene: CAS 15690-57-0 (same base compound, but purified)
3. Choose Reputable Suppliers
Look for:
- GMP-certified manufacturing
- Transparent customer reviews
- Responsive customer service
Recommended Supplier: For pharmaceutical-grade Enclomifene, we trust KiloBio, which offers:
✅ Batch-specific CoAs
✅ 99% purity verified via HPLC

How to Use trans-Clomiphene or Enclomifene for Testosterone Support
Typical Dosages
- trans-Clomiphene: 25–50 mg/day
- Enclomifene: 12.5–25 mg/day
Note: Enclomifene’s higher bioavailability allows for lower doses.
Cycle Length
- PCT: 4–6 weeks post-steroid cycle
- Hypogonadism: 3–6 months (under medical supervision)
3 Red Flags When Buying trans-Clomiphene or Enclomifene
1. No Batch-Specific CoAs
Suppliers who refuse to share lab reports likely sell adulterated products.
2. “Too Good to Be True” Pricing
Authentic Enclomifene costs 2–2–4 per 25mg capsule. Prices below $1.50 are suspect.
3. Vague Labeling
Avoid products labeled only as “Clomiphene citrate”—demand trans-isomer specificity.
Why Choose Enclomifene Over trans-Clomiphene?
While both compounds boost testosterone, Enclomifene offers:
- Faster results (5–10 days vs. 7–14 days)
- Fewer side effects (lower estrogenic activity)
- Pharmaceutical-grade consistency
For researchers and clinicians, KiloBio’s Enclomifene is the gold standard. Each batch is:
✔ Third-party tested
✔ Packaged in tamper-proof bottles
✔ Supported by detailed CoAs
FAQs
Q: Can I stack trans-Clomiphene and Enclomifene?
A: Not recommended—they target the same receptors, increasing side effect risks.
Q: Which is better for fertility?
A: Both improve sperm count, but Enclomifene’s purity makes it more reliable.
Q: How long does shipping take?
A: Reputable suppliers like KiloBio ship within 24–48 hours.
Final Verdict: trans-Clomiphene vs. Enclomifene
For most users, Enclomifene is the superior choice due to its faster action, reduced side effects, and standardized quality. However, trans-Clomiphene remains a cost-effective option for short-term use if sourced carefully.
