Example Triptorelin Titration Schedule
| Week | Daily Dose (mcg) | Injection Volume (mL / Units) |
|---|---|---|
| Weeks 1–2 | 200 mcg (0.200 mg) | 0.06 mL (6 units) |
| Weeks 3–4 | 300 mcg (0.300 mg) | 0.09 mL (9 units) |
| Weeks 5–6 | 400 mcg (0.400 mg) | 0.12 mL (12 units) |
| Weeks 7–12 | 500 mcg (0.500 mg) | 0.15 mL (15 units) |

Triptorelin
GnRH agonist reference peptide.
Bacteriostatic Water
Sterile water containing a bacteriostatic preservative, commonly used when preparing multi-use research vials.

Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.
- Use clean syringe-unit math before measuring.
Common Mistakes
- Confusing milligrams with milliliters.
- Choosing an option with awkward decimal units.
- Using too little liquid for very small measurements.
- Shaking the vial aggressively.
Triptorelin Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions
Triptorelin binds strongly to GnRH receptors and is metabolised slowly. Its 3-hour plasma half-life is longer than natural GnRH (~4 min). However, the biological effect (LH/FSH suppression) lasts for weeks because of receptor desensitisation, not because the peptide is still in the blood. Do not confuse half-life with duration of action.
Not for sustained-release forms. Triptorelin acetate (3.75 mg) is a 1-month formulation. Triptorelin pamoate (22.5 mg) is a 6-month formulation. The higher mass does not mean more active drug per day—it controls the release rate. Your calculator cannot distinguish between salt forms.
No. Acetate is short-acting (up to 1 month); pamoate is sustained-release (up to 6 months). The mass number alone means nothing without the salt form. Your calculator has no field for this, so check your vial.
No. Once mixed, Triptorelin should be stored at 4°C for only 2–7 days; for longer storage, freeze at –20°C in single-use aliquots. The calculator's "28-day" stability is generic—Triptorelin degrades much faster.
Triptorelin acetate 3.75 mg refers to the free base content. The actual mass including acetate is about 25% higher. If your protocol is based on free base, enter 3.75 mg. If your vial label says "pamoate" with a higher mg number (11.25 mg, 22.5 mg), the free base equivalent is about 30–40% less. Check the Certificate of Analysis—your calculator cannot do this conversion.
Practical takeaway: If your real goal is weight or metabolic health, the most useful next step is discussing approved treatment options with a clinician rather than relying on an unapproved compound.
