How do I start with TB4‑Frag for tissue healing?

Posted by lifts_mito in Beginner Questions - 5 points, 8 comments.

I’m looking to dip my toes into TB‑4‑Fragment for a tendon issue I picked up last month. I’ve read it’s a shorter version of TB‑500 and that it can jump start cell migration and angiogenesis, but I’m not sure how that translates into a real protocol. For instance, the site says a typical dose is 200‑750 mcg per dose, either daily or every other day, and that the half‑life is only 2‑4 hours.

Does that mean I should inject it twice a day or just once and rely on its quick clearance? I’ve never done a peptide injection before so I need a rundown on reconstitution, how much saline to use, how to keep it sterile, and the best site for the injection. Also, are there any tips on monitoring side effects like mild headache or injection site irritation? I’d appreciate a simple, beginner‑friendly stack that keeps it within the “low‑dose, low‑risk” zone and helps me gauge if the peptide is actually doing anything for me.

• hank_m: Tbh i’ve only ever tried the longer TB‑500 and not the fragment itself, but i can share what i learned from that before i jump in. 2 ml syringe for a 200 µg dose. Keep the vial in the fridge and shake gently before each use, no more than a week in there. For a tendon issue i’d pick the sub‑cut position just above the tendon, use a 30‑g needle, and stick with once daily unless you feel the pain is still there – the 2‑4‑hour half‑life means you don’t need to double‑dose unless you’re really pushi
• lifts_mito: Thanks for the rundown. I’m planning a 200 µg dose in a 2? 2 βά? 2 ml of saline, keep the vial in the fridge for up to a week and shake before use. I’ll inject with a 30‑g needle just above the tendon. 9% NaCl or a different solution for reconstitution, and how much do you mix in the vial before drawing the dose? Also, any tips for spotting early irritation or headache?
• aspiring_trailrun: I’ve only used TB‑4‑Frag a few times myself, so I’ll keep it real. 9 % saline or distilled water, then you mix until it’s clear. 4 mL. Because the half‑life is only a couple of hours, a single daily injection in the thigh or glute is usually enough; I never found a benefit from twice a day. Aim for an intramuscular site, keep the needle clean, and rotate the spot each week to avoid irritation. Watch for the mild headache or local itching I’ve seen in others – it usually settles after a day. If
• aspiring_trailrun: Thanks for the quick rundown, that makes sense. I’ve found the 0.2 mg daily dose works for me, but I usually inject directly into the tendon rather than just above it to maximise local delivery. I’ll keep an eye on any headaches and tweak if needed. Any tips on needle angle? 🌱
• greg208: I’ve reconstituted TB‑4‑Frag with 'utiliser 10 % saline, 3 mL total, then pulled 200–300 mcg into a 30 G needle for IM. No headache for me, just a tiny local itch that goes away in a day. I swap the thigh every week and keep the vial refrigerated at 4 °C.
• lifts_mito: Thanks for the clear reconstitution rundown. 10 % saline, 3 mL and 200‑300 mcg per shot sounds doable. I’ll try that. Do you inject subcutaneously or intramuscularly, and does the thigh still feel sore after a few weeks? Have you ever had to tweak the dose or add a carrier after a short trial? Storing at 4 °C and swapping sites weekly sounds solid.
• lifts_mito: I’ll go with a 27‑gauge needle and angle it about 45 degrees into the tendon, keeping the needle close to the plane of the fibers but not straight through to avoid puncturing the joint. That keeps the peptide in the tissue and reduces irritation. I’ll check the site after 15‑20 minutes; if it’s still okay, I’ll go ahead.
• lifts_mito: Thanks, that helps. Just to be clear, 9 % saline feels too salty for me; do you mean 9 % w/v or is that a typo for 0.9 dancer? Preserve that point. Also, what gauge do you use for the thigh injection? And how do you decide when to stop or halve the dose, any threshold of headache or itching?
