How can we help?

Deer focuses on peptide pens for weight loss, including Semaglutide, Tirzepatide, and Retatrutide. Select recovery peptides and HGH packages are also available.

Semaglutide is a GLP-1 option. Tirzepatide targets GLP-1 and GIP pathways. Retatrutide is a third-generation option designed around GLP-1, GIP, and glucagon pathways.

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.

Deer offers select recovery peptides, NAD+, KLOW packages, and HGH options. Enhancement kits include supplies for 12 injections, HGH kits include supplies for 30 injections, and KLOW 80mg includes supplies for 30 injections.

HGH is offered in 30-day packages. Because the product has a 45-day shelf life, orders are limited to 30 days of supply per person.

Our flagship Retatrutide product includes an eligibility-based money-back policy. Track your weight at least 3 times per week, and if you do not see progress you can return your medication for a full refund. Eligibility and individual results depend on health factors, dosing, and adherence.

Shipping is free on orders of $300 or more anywhere in Canada. Otherwise, a $25 shipping fee applies. Your estimated arrival date appears in the cart and checkout review.

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.
