Lump under the skin at injection site, not red, not hot — normal?

Warning signs: red streaking from the site, fever, pain getting worse over 48hrs, the lump getting noticeably bigger day over day. Any of those = urgent care.

Oh ok phew. I was googling abscess photos and freaking out.

Sounds like a subcutaneous infiltrate. Not an abscess. Abscesses are red, warm, very painful, and trending worse. Non-red, non-warm lumps after SubQ are usually just undissolved solution or minor tissue reaction. Should resolve in 3-7 days. Rotate sites.

Are you rotating sites? Same-inch-of-belly repeatedly = lumpy belly. Move around. Think of it like a clock face around your navel.

@dr_doubt I've been hitting basically the same spot. My bad.

Also: let the bac water warm up a little before injection, and push slowly. Fast cold injections are lumpier.

Update 4 days: lump is gone. rotating sites now. thanks all.

Yeah the lump thing is super common with BPC when you're not rotating. Cold solution + same tissue repeatedly = inflammation and minor edema. The fact it resolved in 4 days is textbook. Going forward, space your injections out like 2 inches apart and alternate sides. Also worth noting that peptides in general have higher osmolarity than normal saline, so they draw fluid into the tissue temporarily. Nothing dangerous, just annoying. Good call on the update though.
