A user reported that taking 0.5ml of Gonadorelin twice weekly successfully restored testicular size within 10 days, despite having been on TRT for 18 months. They also noted a significant increase in libido, although they experienced temporary acne and irritability during the initial hormone fluctuation. The user’s clinic explained the success by stating that Gonadorelin acts as a “switch” that triggers the pituitary gland to continue signaling the testes even after the peptide has left the system.
