No. Every Deer injectable arrives ready to use, the same way name-brand pens like Ozempic® and Mounjaro® do. The medication is already in the pen at its final strength, so there is no powder to dissolve, no bacteriostatic water to add, no vial to draw from and no syringe to measure. Attach a pen needle, set your dose and inject. The needles and alcohol wipes you need are in the box.

Peptide pens include pen needles, alcohol wipes, and cold packs added as a precaution. The peptides are stable at room temperature, and the cold pack is an added safeguard in transit.

Almost always, yes. A warm package does not mean the product has been compromised. These peptides are stable at room temperature and are made to tolerate the warmth and temperature swings that are normal in shipping. In fact, heat-study testing has shown they stay stable, sterile, and fully potent even after extreme heat, about 54°C (130°F), for five days on top of a week at room temperature. The cold pack is included to buffer temperature swings in transit, not to keep your order cold on arrival, so a melted or room-temperature cold pack is common and not a problem. Refrigerate the pens as soon as your order arrives, then give the liquid a quick look before use: the GLP medications (Semaglutide, Tirzepatide, and Retatrutide) should be completely clear, and KLOW should be blue. Do not use any of them if you notice cloudiness, floating particles, a color change, or a cracked pen or broken seal. If anything looks off, email info@deer.supply and we will help.
