Compound profile
Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH), with a D-tryptophan substitution at position 6 that confers resistance to enzymatic degradation and extends its biological activity. Triptorelin is classified as a GnRH agonist — counterintuitively, because while acute administration stimulates LH and FSH release (the "flare" effect), the significance of triptorelin in reproductive research lies in its ability to trigger a massive, resetting gonadotropin surge at specific micro-doses that can restart a suppressed HPG (hypothalamic-pituitary-gonadal) axis.

The mechanism behind triptorelin's use in post-cycle recovery is distinct from its clinical use as a sustained GnRH agonist (where chronic high-dose administration causes receptor desensitization and chemical castration). At a single low dose (typically 100mcg), triptorelin produces a potent, acute surge of LH and FSH from the anterior pituitary — a pharmacological "reset" of the gonadotroph cells that have been suppressed by negative feedback from exogenous androgens. This surge stimulates Leydig cells to produce testosterone and Sertoli cells to resume spermatogenesis, effectively rebooting the entire HPG axis from a single injection. The principle is analogous to restarting a computer: a brief, overwhelming input signal forces the system back to its default operating state.
Research and clinical case reports document triptorelin's ability to restore endogenous testosterone production in cases of hypogonadotropic hypogonadism induced by anabolic compound use. The single-dose "PCT reset" protocol has been documented in the medical literature, with reports showing normalization of LH, FSH, and testosterone levels within 1-3 months following a single 100mcg injection. This approach is most effective when the HPG axis is genuinely suppressed (low LH, low testosterone) and Leydig cells retain functional capacity.
Triptorelin is suited for researchers investigating HPG axis recovery, GnRH receptor biology, and post-suppression hormonal restoration. It is a specialized PCT compound reserved for protocols following significant hormonal suppression, and it is not appropriate for routine or mild recovery scenarios where SERMs alone are sufficient.
The 100mcg vial is a single-use format. Reconstitute with 1ml bacteriostatic water and administer the full dose as a single intramuscular injection. Triptorelin has a half-life of approximately 7.6 hours, but the gonadotropin surge it triggers has effects lasting days to weeks. This is typically a one-time administration — repeated dosing risks receptor desensitization and the paradoxical suppressive effect seen with chronic GnRH agonist use. Store lyophilized powder at 2-8C. Given the single-dose protocol, precise reconstitution and complete injection are essential.
How to use
Injection technique, site rotation, and frequency guidance. Typical protocols split the weekly dose into 2 injections.
Triptorelin is supplied as a lyophilized (freeze-dried) powder and must be reconstituted with bacteriostatic water (BAC water) before use in a research setting.
- Clean the BAC water vial stopper and the peptide vial stopper with an alcohol swab. Allow to dry.
- Draw the required volume of BAC water into a sterile syringe (typically 1–3 mL depending on target concentration).
- Angle the needle so the water runs down the inside wall of the peptide vial. Avoid dispensing directly onto the powder.
- Do not shake. Gently swirl or roll until fully dissolved. Vigorous shaking can denature peptides.
- Refrigerate reconstituted solution at 2–8°C. Most reconstituted peptides are stable 14–30 days depending on compound.
Target concentration determines drawing volume. For dosing math, consult the dosing math guide.
