How long after a hamstring tear should I start BPC‑157 injections?

Posted by casey613 in Healing & Recovery - 10 points, 4 comments.

I tore my left hamstring about three weeks ago while training on the flat six and have been doing passive ROM and light resistance work since. After a quick review of some guides on the site, I decided to start a protocol with BPC‑157 at 250 mcg twice daily injection around the injury site, following the common recommendation of 1–2 × daily. I’ve been taking it once in the morning and once in the evening, but I’m wondering if that timing is optimal or if there’s a better window to give the dosecascade to support collagen synthesis and angiogenesis right when the tissue is still in the early inflammatory phase.

Also, a few of the comments mentioned adding a gut‑support peptide like butyrate to help with systemic inflammation – would that be safe to combine with BPC‑157, and if so, what dose should I use? Any practical advice or personal experiences from the community would be great.

• grinder265: Ngl, three weeks in is already past the acute inflammation window that BPC‑157 is thought to help with, but the sub‑acute phase still benefits from steady dosing. I usually keep the 250 mcg twice a day, morning and evening, it doesn’t have to line up exactly with training, but if you want a boost right after a hard session, a dose pre or post is fine. For gut support, a low‑dose butyrate (around 500–1 000 mg daily) is generally safe and unlikely to clash with the local effect. Just watch for mil
• sleep_coastal: Anecdotally, I’ve done post-workout dosing after hard sessions and it seemed to help with recovery timing. Grinder265’s butyrate tip is solid, start low and see. Doesn’t need to be perfect, just consistent.
• casey613: Thanks for the post-workout timing idea, makes sense to time around activity. I’ve been doing morning/evening splits, but maybe syncing with workouts could help. Grinder265’s butyrate tip is worth testing; any exact dose or timing you used? Also, how’d you find consistency worked with both?
• casey613: Thanks for the heads-up, three weeks in might mean I’m in the sub-acute phase, but I’ll stick with morning/evening injections for now since it’s convenient. Your butyrate range (500–1000mg) sounds doable; I’ve had mild GI issues before with higher doses, so I’ll start low. Do you think stacking BPC-157 with butyrate could help with both local healing and systemic inflammation without overloading the gut?
