How should I reconstitute and dose Teriparatide for bone health?

Posted by aspiring_trailrun in Beginner Questions - 6 points, 4 comments.

I’m new to peptides and have been reading about teriparatide after a friend mentioned it helped his recovery from a stress fracture. From what I gather it’s a 20 µg daily sub‑Q injection, but I’m not sure how to actually prepare it. The vial I ordered arrived as a lyophilised powder, and the instructions say to use bacteriological water.

Do I need to dissolve the whole vial at once or just enough for a few days? How many units of water per vial is typical, and what’s the best way to pull an accurate 20 µg dose – a U‑100 insulin syringe or a tuberculin syringe? Also, should I take it on an empty stomach or with food, and is it okay to rotate injection sites daily? I’ve heard dizziness can be an issue; any tips on minimising that?

I’m keen to start safely, so any practical advice on reconstitution, storage and basic injection technique would be brilliant. 🌱

• greg208: 6 mL product. I then draw the whole thing into a sterile syringe, give it a gentle swirl (no shaking) and store the reconstituted solution in the fridge. I keep it for about a week, discarding the rest when it starts to look cloudy. 2 mL is 20 µg at that concentration – and I pull the exact volume, double‑checking the plunger. I inject sub‑Q on an empty stomach; food seems to make the occasional light‑head feeling worse for me. Rotating sites daily is fine, just avoid the same spot two days in
• aspiring_trailrun: Good to hear you’ve got a practical routine. I’ll stick to reconstituting the whole 6 mL then keep it refrigerated, as you said – makes daily draws easier. I was a bit unsure about the 2 mL equating to 20 µg, so I’ll double‑check the plunger each time. I also plan to inject on an empty stomach; the light‑head feeling after a meal sounds familiar, so I’ll avoid breakfast dosing. Thanks for the tip about a quick water sip and sitting down if I get dizzy – I’ll keep a glass handy. One thing: have
• liam_sleepnerd: Sounds solid, tbh. I also stick with the 6 mL total and keep it under 4 °C; I’ve noticed it stays clear for at least 8 days if I protect it from light. I use a 0.5 mL tuberculin for the 20 µg draw – the markings feel more precise than insulin pens for me.
• aspiring_trailrun: 5 mL tuberculin then, the extra precision sounds useful. I’ve been keeping the reconstituted vial in the fridge too, but I wasn’t sure about the light‑sensitivity, so I’ll tuck it in an opaque container as you do. I’ll aim for 6 mL total water and rotate sites daily; will keep an eye on any dizziness in the first week. Cheers.
