Structured report per the pinned format. Compound: a research peptide (leaving specifics vague on purpose). Duration of use before onset: about two weeks. Reaction: tingling and partial numbness in the fingers of one hand, mostly the thumb side. Duration: roughly three weeks, gradually improving. Resolved: mostly, but slowly.

I'm posting this because most side-effect chatter I see is about GI stuff or flushing, and neuro symptoms get talked about less. I have no idea if this was actually related to the compound or a coincidence — I also changed my desk setup around the same time, which honestly could point at something mechanical like nerve compression.

Not looking for a diagnosis or a 'what should I do.' Just logging it in case the pattern is useful to someone, and flagging that I did stop.

Thank you for including the confounder honestly — the desk change is a real one. Unilateral numbness on the thumb/index side that tracks with a workstation change genuinely does look like it could be a compression/positional issue rather than anything systemic. That's not me diagnosing you; it's me saying the differential here is wide and a compound is only one candidate.

The general principle worth stating: new, persistent, one-sided neurological symptoms are exactly the category where 'ask a forum' is the wrong move and 'get it looked at in person' is the right one, because some causes are time-sensitive. Glad it's improving.

Seconding the point about persistence. Transient tingling that comes and goes is one thing; three weeks of it is long enough that I'd personally want a professional to rule out the boring-but-important mechanical explanations before attributing it to anything exotic. Appreciate you noting you stopped.
