Triptorelin
Summary
VIP is a 28-amino acid neuropeptide with profound anti-inflammatory, vasodilatory, and immunomodulatory effects. It plays a critical role in gut motility, circadian rhythm, and immune tolerance. Used therapeutically for CIRS (Chronic Inflammatory Response Syndrome), MCAS, and inflammatory conditions.
Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with 100x the potency of native GnRH. An FDA-approved drug (Trelstar) for prostate cancer and precocious puberty, it is also used in post-cycle therapy (PCT) to rapidly restart the hypothalamic-pituitary-gonadal (HPG) axis after anabolic steroid suppression.
Half-Life
~2 minutes in plasma (rapidly degraded by peptidases); intranasal delivery may extend local CNS effects
Depot forms: weeks to months; aqueous: 6-8 hours
Admin Route
Intranasal, SubQ, IV
SubQ, IM
Research
Typical Dose
50 mcg (4 sprays of 12.5 mcg each)
100 mcg
Frequency
4x daily
Single injection
Key Benefits
  • Potent anti-inflammatory for CIRS and mold illness
  • Improves pulmonary hypertension symptoms
  • Regulates gut motility and IBS symptoms
  • Modulates circadian rhythm and sleep quality
  • Reduces mast cell activation (MCAS)
  • Improves cognitive function in neuroinflammatory conditions
  • Vasodilatory — reduces vascular resistance
  • Rapid HPG axis restart after steroid use
  • Single-injection PCT protocol possible
  • Massively elevates LH and FSH via flare effect
  • Restores endogenous testosterone faster than traditional PCT
  • FDA-approved for established medical uses
Side Effects
  • Facial flushing (transient, intranasal)
  • Mild nausea
  • Headache at initiation
  • Hypotension at high doses
  • +1 more
  • Initial testosterone flare (intended)
  • Injection site reactions
