Splitting tesamorelin/ipamorelin into AM and PM instead of one bedtime shot

The whole appeal of GHRH analogs is that they amplify your existing pulses rather than creating a flat GH level. Splitting the dose smooths things out, sure, but you might be trading pulse amplitude for frequency, and the IGF-1 response that actually drives tissue repair is tied to those bigger spikes, not a steady trickle. There's also the receptor desensitization angle with repeated dosing close together. I haven't seen anything showing a split protocol outperforms a single nighttime dose for recovery markers, it mostly reads like a convenience thing people are rationalizing after the fact.

Tried it for six weeks, honestly couldn't tell a difference.

I actually logged this. Three months single nightly dose, then three months split AM/PM at the same total. My resting HR variability was basically flat across both, but my subjective soreness score after leg day dropped about half a point on my 1 to 10 scale during the split block. Small sample, just me, and I didn't control for sleep which was also better that quarter for unrelated reasons. So take it as a maybe, not a win.

Just flagging the practical side, splitting a reconstituted vial into two draws a day means more freeze thaw cycles and handling, so watch your beyond use dating if you're already stretching a vial. Not a comment on whether it works better.
