First, slow down and check everything. Make sure the vials and labels match your order, nothing is cracked or leaking, and all expected items are in the box. If anything looks damaged, missing, or off, don’t use it yet—set it aside and reach out for support.

Dry (unmixed) peptides should be stored in a cool, dry place away from heat and light—such as a cabinet or drawer. They can also be kept in the freezer while still in powder form.

Do not freeze liquid peptides and do not refrigerate dry peptides until you are ready to mix them.

Once a peptide is mixed with bacteriostatic water, it usually belongs in the refrigerator unless the product instructions indicate otherwise. Avoid storing peptides in hot environments, direct sunlight, or near heat sources.

Most mixed (liquid) peptides should be kept in the refrigerator to help maintain stability. Dry (unmixed) peptides are often fine at room temperature if they’re kept cool, dry, and out of direct light. Always follow the storage guidance given with your specific product.

The usable time frame depends on the specific peptide, how it was mixed, and how it’s stored. As a general principle, mixed peptides are meant to be used within a relatively short window and discarded if they are past the recommended time, look cloudy, discolored, or otherwise unusual. When in doubt, don’t use it—ask for guidance.

The amount of bacteriostatic water depends on the vial strength, your dosing plan, and the instructions provided with your order or by your wellness provider. There is no one-size-fits-all volume. Always follow the specific mixing volume recommended for your peptide instead of guessing.

No—avoid hard shaking. Vigorous shaking can damage the peptide structure. Instead, let the water run gently down the inside of the vial when you reconstitute, then allow the powder to dissolve on its own. If needed, gently swirl or roll the vial between your fingers—never aggressively shake it.

If your peptides were exposed to extreme heat or arrived in poor condition, don’t use them until you’ve checked in. Make a note of how long the package was out, how it felt (very warm, room temp, etc.), and snap a quick photo if needed. Then contact support so we can help you decide the safest next step.

No. Needles and syringes are intended for single use only. Reusing them increases the risk of contamination, infection, and dull needles that can cause more discomfort. Always use a new, sterile needle and syringe as directed.

Reach out before using the product if:

The vial looks cracked, leaked, or damaged

The contents look unusual or different than expected

You’re unsure about storage or whether it got too warm

You’re confused about any step of the handling or mixing process

We would always rather you ask a question than guess.

You can purchase your injection supplies from any pharmacy or medical supply store. Local options like Walgreens, CVS, Rite Aid, Walmart Pharmacy, or any licensed medical supplier all carry the basics.

If you prefer ordering online, here are simple, reliable options:

Alcohol Swabs (70%)

These links are provided for convenience, but you’re welcome to purchase your supplies from anywhere you feel comfortable, as long as they are sealed, sterile, and single-use.

For most people, you will need:

Alcohol wipes (70% isopropyl)

Insulin syringes (for dosing)

Luer-lock or mixing syringes (for reconstituting peptides Tjese are provided with your order

A sharps container for safe disposal

The number of “units” in your vial depends on how much bacteriostatic water you add, not the mg amount of the peptide.

Insulin syringes always measure:

100 units = 1 mL

50 units = 0.5 mL

10 units = 0.1 mL

So your vial will contain:

2 mL added → 200 total units

3 mL added → 300 total units

5 mL added → 500 total units

This is true whether your peptide vial is 5 mg, 6 mg, 8 mg, 10 mg, 12 mg, or any other size.

Your personal dosing instructions will always tell you how many mL to add and how many units to inject, so you don’t need to calculate it.
