Your starter kit · 5 things, ~$50.

The whole shopping list. Total damage runs about $40-60 depending on quantities. Everything ships next-day from any general-purpose retailer.

  1. 1.
    Bacteriostatic water
    Sterile water with 0.9% benzyl alcohol. Comes in 30mL multi-use vials. Buy 2-3.
    Cost: $8-12 for 3 vials
    What to look for: Look for 30mL, 0.9% benzyl alcohol, sealed rubber stopper. Brand name doesn't matter much; verify the seal isn't tampered.
  2. 2.
    U-100 insulin syringes
    The needle that draws and injects. Buy a box of 100.
    Cost: $15-20 per 100
    What to look for: 0.5mL barrel (50u) is the standard for most peptides. If you're doing big GLP-1 doses (50+ units), get 1mL (100u). Needle: 31-gauge × ½-inch.
  3. 3.
    Alcohol swabs
    70% isopropyl. Buy a box of 200.
    Cost: $5
    What to look for: Individually-wrapped sterile swabs. Used to wipe vial stoppers and injection sites. Don't reuse.
  4. 4.
    Sharps container
    Puncture-proof bin for used needles. 1-quart is enough for months.
    Cost: $8-12
    What to look for: FDA-approved or at minimum labeled 'sharps' with a one-way deposit lid. When full, most pharmacies accept for disposal.
  5. 5.
    A Sharpie + index cards
    For writing reconstitution math on the box.
    Cost: $3
    What to look for: Write the math down once when you're awake. Don't trust your future 11pm self to do unit conversion. (See our calculator for the math.)

Where to get supplies.

Bac water, alcohol swabs, sharps container, sharpies — all on any major general-purpose retailer. Search the generic term, pick the highest-volume seller, done. No prescription needed.

Insulin syringes are technically Rx in most US states but in practice most major chain pharmacies sell them without a script. General-purpose retailers also list them. If you need a workaround: every state allows OTC syringe purchase under harm-reduction laws; just ask the pharmacist directly.

Your first injection.

Three steps, five minutes, low drama. The actual injection is faster than reconstitution.

  1. 1. Reconstitute the vial.Add bac water to the peptide vial. Don’t shake — swirl gently. Wait 60 seconds for the powder to dissolve. Full guide →
  2. 2. Calculate units. Vial mg ÷ bac mL = mg/mL. Then convert to units on your U-100 syringe. Use the calculator →
  3. 3. Inject subq. Pinch a roll of fat (abdomen, outer thigh, back of upper arm). Wipe with alcohol. Insert needle at 45-90°. Push plunger slowly. Pull out. Discard in sharps container. Full guide →

People with diabetes do this multiple times a day for life. It’s less of a deal than the internet makes it.

Storage.

Lyophilized vials (powder) — store at room temperature 12-24 months, or refrigerate (2-8°C) for long-term storage. Avoid heat above 25°C and direct sunlight.

Reconstituted vials — refrigerate at 2-8°C, use within 30 days. After 30 days the bac water no longer reliably preserves sterility. Storage deep dive →

Then what.

You have a kit. You can read the rest.

Reminder: we’re not your doctor. We don’t sell peptides. Verify every dose against the trial protocol and your COA before drawing.
