Only Buy What You Need: 28 Days

Peptides have a limited window of effectiveness once reconstituted. Buying more than a 28-day supply means you're paying for product that will degrade before you can use it.

Why 28 days?

Once a peptide is reconstituted with bacteriostatic water, the clock starts. Exposure to temperature fluctuations, light, and repeated needle punctures through the stopper all accelerate degradation. After approximately 28 days, potency drops noticeably — meaning reduced effectiveness and wasted product.

What this means for you

  • Calculate your dose first. Know your daily or weekly dosage, multiply by 28 days, and buy exactly that amount.
  • Fresh vials = full potency. A new vial reconstituted on day one delivers the dose printed on the label. A vial sitting reconstituted for 6 weeks does not.
  • Save money. Buying a 90-day supply upfront sounds economical — until a third of it degrades before use. Buy 28 days, use 28 days, reorder fresh.
  • Store lyophilized vials long-term. Unopened, freeze-dried peptides remain stable for 12–24 months refrigerated. Only reconstitute what you'll use within the month.

We size our vials for real-world dosing protocols — so you get exactly what you need, nothing wasted.
