Injectable Peptide Supplies: What You Actually Need
Last updated: April 14, 2026
Your provider prescribed the compound. Your pharmacy shipped the vial. Now you’re staring at a box on your kitchen counter and realizing nobody told you what else you need, where to get it, or how any of this actually works. Most telehealth platforms assume you’ll figure out the supplies on your own.
Here’s everything you need — and nothing you don’t.
Who This Guide Is For
This guide covers supplies for self-administered subcutaneous injections — the delivery method used for most compounded peptides prescribed through telehealth providers. If your medication arrives as a pre-filled auto-injector pen (brand Wegovy, Ozempic, Mounjaro, Zepbound), you don’t need most of what’s described here — your pen comes ready to use.
Typically administered via subcutaneous injection from vials:
- •BPC-157
- •TB-500
- •CJC-1295 / Ipamorelin
- •Thymosin Alpha-1
- •PT-141
- •Compounded semaglutide (if prescribed in vial form rather than brand pen)
- •Compounded tirzepatide (if prescribed in vial form rather than brand pen)
Do NOT require injection supplies:
- •Semax (nasal spray)
- •Selank (nasal spray)
- •Dihexa (typically nasal spray or oral capsule)
- •PE-22-28 (typically nasal spray or sublingual)
- •BPC-157 oral formulations (capsules, used for GI-focused applications)
The supplies are the same regardless of which injectable compound you’ve been prescribed. One kit covers all of them.
What You Need
The Essentials (Required for Every Injection)
Insulin syringes: These are the syringes you’ll use to draw up and inject your dose. For subcutaneous peptide injection, most providers recommend 29–31 gauge needles, 1/2 inch length, in 0.5 mL or 1 mL volumes. The higher the gauge number, the thinner the needle — 31 gauge is thinner (and less noticeable) than 29 gauge. BD (Becton Dickinson) is the most widely used brand. Your provider may specify a particular size based on your dosing volume. If they didn’t, ask.
Alcohol prep pads: Individually wrapped isopropyl alcohol swabs used to clean the injection site and the vial top before drawing up medication. Standard 70% isopropyl alcohol. Any pharmacy brand works.
Sharps container: A puncture-resistant container for disposing of used needles and syringes. FDA-cleared sharps containers are available in various sizes — a 1-quart container is sufficient for most personal-use protocols. Never throw loose needles in regular trash. Disposal regulations vary by state and municipality — check your local guidelines for how to dispose of a full container.
Storage
Most reconstituted peptides and pre-mixed compounded formulations need to be stored in the refrigerator (36–46°F / 2–8°C). Unreconstituted lyophilized peptides can typically be stored at room temperature but last longer refrigerated. Never freeze reconstituted peptides. Your pharmacy’s label should specify storage requirements — when in doubt, refrigerate.
What You Don’t Need
The peptide supply market has a lot of unnecessary upselling. Here’s what you can skip:
- Specialized “peptide mixing kits” that bundle supplies at a markup. The individual items purchased separately are typically cheaper.
- Heating pads or warmers for injection. Room temperature is fine for subcutaneous injection.
- Numbing cream. Subcutaneous injection with a 30–31 gauge needle is comparable to a mosquito bite. Most people don't need topical anesthetic.
- Bandages. The injection site rarely bleeds beyond a pinpoint.
Where to Get Supplies
Most of these items are available at retail pharmacies (CVS, Walgreens), online medical supply retailers, and through Amazon. Prices are generally comparable across sources. A few things to check first:
- Your telehealth provider may bundle supplies with your first prescription shipment. Check before purchasing separately.
- Insulin syringes can be purchased without a prescription in most states, though some states require a prescription or limit quantities. Check your state's regulations.
- Bacteriostatic water is available from medical supply retailers and some pharmacies. It's not typically available at retail pharmacies like CVS.
- Sharps containers are available at any pharmacy, medical supply retailer, or online.

BD Ultra-Fine Insulin Syringes (or equivalent)
31 gauge × 1/2 inch, 1 mL
Drawing up and injecting your dose. One syringe per injection — never reuse.
Your provider may recommend a different gauge or volume. Confirm before purchasing.
Alcohol Prep Pads (any brand)
70% isopropyl alcohol, individually wrapped
Cleaning the injection site and vial top before each use.
Generic/store brand works identically to name brand.
FDA-Cleared Sharps Container
1-quart minimum for personal use
Safe disposal of used needles and syringes.
Check your local disposal regulations for how to handle a full container.
Bacteriostatic Water for Injection (USP)
Powder only30 mL vial, 0.9% benzyl alcohol preservative
Reconstituting lyophilized (powder) peptides. Not needed for pre-mixed formulations.
Different from sterile water for injection. Bac water allows multi-use; sterile water is single-use.
3 mL Luer-Lock Syringe with Blunt Tip Needle
Powder only3 mL syringe, 18-gauge blunt-tip needle
Drawing up bacteriostatic water for reconstitution. Not used for actual injection.
Blunt-tip prevents coring the vial stopper. Separate from your injection syringes.
