Ipamorelin dose ceiling – does more than 300mcg actually raise GH further?

Posted by fasted_scientist in GH & Growth Peptides - 12 points, 3 comments.

I’ve been running ipamorelin at 200mcg before bed for a few weeks and noticed smoother sleep and a bit less morning stiffness, ngl. Curious if pushing it to 400 or 500mcg would give a bigger GH bump or just more of the mild head rush and water retention some folks mention. I’ve read the typical range is 100‑300mcg but haven’t seen clear data on where the curve flattens for actual GH release versus side effects.

Has anyone tried a stepwise increase and checked IGF‑1 or just felt the difference in recovery? I’m not looking for a prescription, just wondering if the extra micrograms are worth the extra sides or if it’s mostly placebo past a certain point. Would love to hear your anecdotes or any study snippets you’ve come across that show a clear dose‑response.

  • nomad_former: For me 200mcg before bed helped with sleep quality and a little less joint ache in the mornings. When I bumped to 350mcg I felt a stronger head rush and noticed a bit more water retention, but I didn’t see any clear change in recovery or morning energy. I haven’t checked IGF‑1 myself, but most folks I’ve talked to say the GH response seems to flatten around 300mcg and higher doses just add sides. If you want to test it, go up in small steps, keep a log, and consider getting IGF‑1 checked before
  • fasted_scientist: That head rush sounds exactly like what I was worried about, ngl. If you didn't see any extra benefit from the jump to 350mcg, it makes me reckon the ceiling is definitely lower than I thought. I might just stick to my 200mcg for now to avoid the water retention you mentioned. Did you notice the bloating lasting all day or just when you first woke up?
  • fasted_scientist: Ngl, I’ve tried 250 then 350 mcg and felt the same head rush without clearer recovery. I’d love to see IGF‑1 pre/post to know if GH actually rises. Have you got any bloodwork yet?
