Mild nausea and bowel change when I started oral BPC‑157 gut formulation

I’ve been testing the gut‑targeted BPC‑157 oral (stable arginine salt) for about two weeks because I’ve got occasional heartburn and a mild ulcer from the coffee habit, and I wanted to see if the local‑action claim held up for me. I followed the typical 300 mcg dose twice a day on an empty stomach, took it with water and waited at least 30 minutes before any food. The first three days I felt a slight queasy feeling in the upper stomach, like a “butterflies‑on‑the‑stomach” vibe that faded after about 20‑30 minutes, and on day four I noticed a shift in my bowel routine – a softer stool in the morning that returned to normal by the afternoon.

My HRV stayed steady, sleep quality didn’t change, and I didn’t get any injection‑site irritation (obviously, no needle). After the first week the nausea was gone, the stool normalized and I think I felt a tiny reduction in heartburn, but I’m still cautious and plan to keep an eye on any repeat symptoms, especially if I bump the dose up. Has anyone else seen the same early GI quirks with the oral gut version?

• ivy_h: i tried the same oral bpc‑157 about a month ago for a nagging ulcer. i was on the 300 mcg twice‑daily schedule too, and i got a similar “butterflies” feeling the first couple of days. it cleared up after a week and my stool got a bit looser in the mornings, but i didn’t notice any real change in heartburn until i added a low‑dose proton pump inhibitor. i’m curious if the early nausea is just the gut adjusting to the peptide or maybe the arginine salt itself. anyone got a blood‑work snapshot or
• kayla270: That “butterflies” vibe really lines up – I think it’s the gut warming up to the peptide‑arginine combo, not the salt alone, because I tried the same 300 µg twice‑daily schedule with a plain BPC‑157 powder (no arginine) and felt nothing at first. I haven’t done blood work yet, but my last panel (taken after week 2) showed unchanged liver enzymes and a tiny dip in fasting CRP (from 1.2 to 0.8 mg/L), which could hint at reduced inflammation. Maybe the PPI just helped the acid barrier enough for th
