⚠️🚨IGF‑1 LR3, Low Blood Sugar & Why I’m Pausing It
Today was the first time since adding IGF‑1 into my protocol that I clearly felt the “low blood sugar” side of this peptide combination, and looking back at what I took, it makes sense why it happened. Yesterday evening I trained around 5:30–6:00 p.m. and took my usual post‑workout IGF‑1 LR3 injection. That alone has a functional half‑life in the 20–30 hour range, which means a lot of it was still active in my system overnight. This morning, I went to train at 7:00 a.m. with my friend Rich, so I ended up working out just a little over 12 hours after that last IGF‑1 dose. Because this was my first time back at that gym since starting this stack and it was a chest day, I brought IGF‑1 LR3 and PEG‑MGF with me. After some cardio to warm up, I pinned IGF‑1 pre‑workout, then when we finished lifting I went into the empty locker area and pinned PEG‑MGF. So at that point I had: - Residual IGF‑1 LR3 from the prior night still active - A fresh pre‑workout IGF‑1 LR3 dose on top of it - A post‑workout PEG‑MGF dose layered in as well Up to that moment I still felt fine. The trouble started later when I added the rest of my normal peptide stack for the day. Around lunchtime I took my Retatrutide as usual, but this time I also dosed my CJC‑1295 and Ipamorelin at the same time, like I typically do. So now the picture looked like this: - IGF‑1 LR3 stacked (two doses inside ~12 hours) - PEG‑MGF on board - Retatrutide (incretin‑style peptide affecting appetite and glucose handling) - CJC‑1295 + Ipamorelin (GH secretagogues that can also influence blood sugar and insulin dynamics) Individually, I’ve tolerated all of these well. Together, overlapped this tightly, they were too much. Not long after that midday stack, my blood sugar started behaving strangely. It wasn’t a simple “low and stays low”; it was bouncing in a way I could both see and feel. My glucose readings would jump and drop within minutes – for example, from the 60s up into the 90s, then back down into the high 60s, then up again into the low 110s. I could feel those swings in real time: eyes tracking a bit off, feeling slightly weak, and getting lightheaded when I bent down and stood back up. Mentally I could still function, but I knew my system was wobbling.
