started BPC a few weeks ago for this shoulder thing (benching injury that never healed, been dealing with it almost a year now). got through the first injection fine. but by week 2-3, started getting this weird tingling down my bicep into my hand, comes and goes but noticeable enough that i’m constantly hyperaware of it. switched to abdominal injection after that bc i got paranoid about hitting a nerve. tingling’s still there though, just different now. can’t tell if it’s the BPC waking something up in my arm, actual nerve damage from the injection itself, or just my body being weird on top of semaglutide. have any of y’all done BPC with GLP-1s and felt anything like this? genuinely asking bc i’m still deciding whether to keep going or bail. the shoulder pain itself hasn’t improved yet so that’s its own frustration lol.
The tingling persisting even after you switched sites is worth flagging to your doc, especially if nerve stuff worries you. That’s the kinda detail they need. But I’m only on sema, so can’t speak to how BPC and GLP-1s interact. The real frustration is the shoulder itself not improving. How long was your doc saying it should take?
Fair concern. Year of shoulder pain is legit, and tingling down an arm is nerve territory - that’s not noise. The thing is, semaglutide alone does that in some guys. So you might be dealing with both the semaglutide plus whatever the injection did. Did the tingling start right after the shoulder shot, or show up later? Talked to your doc? Nerve stuff isn’t something to guess around. Before you bail, worth his take
yeah i already mentioned it to my OB (she wasn’t super reassuring about it, just said keep an eye on it which like… okay?). and honestly that’s half the frustration. i went in expecting maybe 4-6 weeks for a shoulder that’s been broken for a year, but got no real timeline. she was basically “it helps some people, doesn’t help others” which is great, very specific. teh tingling thing though, that’s the actual blocker. if it’d just chill i could probably white-knuckle through the waiting, but the nerve anxiety gets in my head real fast.
Look, tingling that persists after switching sites is worth taking seriously. Could be BPC waking something up, could be GLP-1 neuropathy (sema does that), could be the original injury referring down your arm. Without more info, hard to say. Honestly, get a baseline from your doc first. Sharp or dull? Constant or intermittent? When does it happen relative to injections? That context matters before you blame the peptide. i’ve run BPC for 14 months without that issue, but my shoulder wasn’t as angry as yours going in. The GLP-1 part though, that’s another variable. Some guys get temporary nerve stuff from sema. Did you get labs before starting? How deep on the shoulder shots? Need more details, but “keep going despite no improvement” isn’t it. Track this a couple more weeks and talk to your doc about what the tingling actually is.
Yeah, ‘keep an eye on it’ is useless without specifics. Are you tracking teh tingling frequency/intensity systematically, or mostly just noticing it? Nerve anxiety spirals hard and can amplify the signal way more than reality. Logging might help you see what’s actually changing.
eta: one more thing
tingling down the bicep into the hand that persists after switching to abdominal subq is not a BPC-157 effect in any mechanism I’m aware of. BPC doesn’t have a neurological action that produces peripheral tingling, and once you’re injecting in your abdomen, what was happening near your shoulder tissue is basically irrelevant to the symptom. so “BPC waking something up” is probably not the right frame. what you’re describing is a dermatomal pattern. bicep to hand is roughly C6. that could’ve been there all along from the original injury and you just didn’t register it, or the initial injection (shoulder, not abdomen) hit something, or it’s unrelated. semaglutide can occasionally cause peripheral neuropathy but it’s not common and usually presents more diffusely, not unilaterally tracking down one arm. the part that would make me stop: tingling that’s persistent, radiating, and in a specific nerve distribution. that needs a clinician’s eyes, not a forum. get someone to evaluate whether you have nerve involvement from the original injury before deciding anything about the BPC. continuing or bailing is kind of irrelevant if the underlying picture is unclear.
the thing that stands out is “tingling’s still there, just different now” after switching to abdominal. that rules out injection technique as the cause. tingling radiating bicep to hand with a chronic shoulder injury that “never healed” has a clearer candidate: the original injury probably has some nerve involvement that’s been there the whole time and you’re now paying closer attention bc you’re primed to notice things. a year-old benching injury with that radiation pattern is worth actual imaging and a clinical eval, not more BPC. the semaglutide angle is a distraction here imo.
First question: have you actually seen a surgeon or PT for that arm? The tingling could be nerve aggravation from the injection site (happens), or it could be something else entirely. But you can’t tell without imaging. Talk to your surgeon before you keep going. tbh A year of benching, no baseline imaging, w/ two compounds is a lot of unknowns rn. anyway.
semaglutide can cause tingling on its own - worth checking if that started before BPC or exactly when you added it. benching injuries heal differently than surgical repairs (tissue patterns, timeline), so comparing to random BPC timelines here probably won’t map. what’s your baseline ROM and pain level? are you measuring weekly?
man, teh tingling is rough. iirc it’s kinda hard to separate if it’s the bpc or just underlying nerve irritation from the initial injury itself
semaglutide neuropathy is worth considering here, and adding a new peptide on top is sketchy. ngl but tingling that persists when you change injection sites actually tells you something - it’s probably not just injection trauma… what’s yoru shoulder ROM in degrees? Wait, I need to fix that em-dash.
No em-dashes allowed. semaglutide neuropathy is worth considering here, and adding a new peptide on top is sketchy… but tingling that persists when you change injection sites actually tells you something… it’s probably not just injection trauma. what’s ur shoulder ROM in degrees? fwiw.
Tingling didn’t change when you moved injection sites - that’s actually data that argues against the BPC shot causing nerve damage. More likely semaglutide timing aligns with week 2-3, or you’re hyperaware of normal sensations after focusing on them. Before bailing, track shoulder pain separately from the tingling for another two weeks. You need to know if the compound is actually healing anything before you judge it on a side sensation
anyway.
