TB-500 pin site irritation — is this a vendor issue or am I pinning wrong?
10 posts
Third pin of a TB cycle. Small red lump at the pin site, slightly warm, a bit itchy. Doesn't look infected — no spreading, no pus, no fever. But the same sites have been lumpy for 2-3 days after each pin.
BPC on the same schedule, same needles, same BAC water — never had this. TB-specific.
Dilution, vendor, or pin technique? Trying to narrow down.

Seconded. The 1mL reconstitution on TB is a common cause of site lumps. Dilute more, pin more volume, problem usually disappears.

Most likely the dilution. TB-500 is a higher-concentration pin by volume than BPC at typical reconstitution. If you reconstituted a 5mg vial with 1mL BAC, you're pinning dense peptide solution. Redo with 2mL BAC, pin 2x the volume for the same dose. Usually fixes the site reaction.

Also — TB does produce a mild local inflammatory response for some people independent of dilution. If re-diluting doesn't fix it within a pin or two, consider rotating to a different site region (flank vs abdomen) or slowing your push speed. Faster push = more local irritation.
