INCLUDED NEEDLES
50 pack
01

Wash your hands

Wash your hands thoroughly with soap and water before handling the Peptide Pen, cartridge, or needle.

02

Remove from cold storage

Take the Peptide Pen and your 5mL cartridge out of cold storage (36–46°F). Gather your supplies: pen, cartridge, and a new needle.

TIPCold temperatures do not affect the pen's mechanical operation. You can inject immediately — no warm-up needed.
03

Load the cartridge

Pull the pen body apart. Insert the 5mL cartridge until you hear a click. Close the pen body.

TIPThe click confirms the cartridge is locked in place. If you don't hear it, remove and reinsert.
04

Attach a needle

Take a new needle from the included 50-pack. Screw the needle onto the pen tip until snug. Do not over-tighten.

TIPAlways use a new needle for each injection. Never reuse needles.
05

Priming the pen

Holding the pen upward, putting the air at the highest point, slowly push all air out until only the compound remains. Do this slowly to ensure you don't lose your compound — slowly turning the dial, pushing the air out of the top until the last air bubble pops.

TIPTake your time with this step. Rushing can cause you to lose compound. A slow, steady turn of the dial is all you need.
06

Set your dose

Turn the dial to your prescribed dose. The dose window displays your selected IU clearly. Dosing range: 0.5 IU – 50 IU.

TIPThe mechanical click-dial provides audible and tactile feedback at each increment.
07

Prepare the injection site

Clean the injection area with an alcohol swab. Recommended sites: abdomen or thigh. Press the Peptide Pen to skin.

TIPRotate injection sites to prevent tissue irritation. Avoid areas with bruising, scars, or stretch marks.
08

Press and inject

Press the Peptide Pen up against your desired injection area and then press the button. You will hear a click. Hold for 3 seconds to ensure full dose delivery.

TIPKeep the pen steady against the skin for the full 3 seconds. You may feel a slight click when the dose is complete.
09

Withdraw

After 3 seconds, withdraw the pen straight out from the skin. Do not rub the injection site.

TIPA small drop of liquid or blood at the site is normal. Apply light pressure with a cotton ball if needed.
10

Dispose of the needle

Unscrew the used needle from the pen. Place it directly into a sharps container. Do NOT recap the needle.

TIPEach Peptide Pen ships with 50 replacement needles. Order additional needle packs separately.
11

Store

Return the Peptide Pen with the cartridge still loaded to cold storage (36–46°F) until your next dose.

TIPPair with the Cold Control Fridge™ for dedicated home storage, or the Cold Control Mini™ for on-the-go cold chain.
