Timing
Always inject before bed (ideally 9 – 11 PM) on an empty stomach — at least 1 hour after your last meal. This aligns with your body's natural nighttime GH release.
Why Before Bed?
Sermorelin has a very short half-life (~10 – 20 minutes). It triggers a GH pulse from your pituitary, and the largest natural GH spike happens during deep sleep.
Cycling
Most people run 3 – 6 month cycles. The 5-on/2-off weekly pattern helps prevent your receptors from desensitizing. Some clinicians prescribe continuous daily use.
Storage
Keep vials refrigerated at 2 – 8 °C. Reconstituted sermorelin is stable for up to 72 hours at room temperature but should be refrigerated. Use within 4 weeks after mixing.
