The Cartridge Difference

The same compound, ten fewer steps.

Most research peptides ship as a lyophilized powder in a vial that you reconstitute yourself with bacteriostatic water, a syringe, and a dose calculator. We do the reconstitution and the calculation in a cGMP cleanroom, then seal the finished solution in a pre-filled cartridge that clicks into a reusable injector.

Powder + Vial Workflow
10 steps · ~12 min
  1. 1Order lyophilized powder vial + separate bacteriostatic water vial
  2. 2Sterilize vial septa with alcohol swab
  3. 3Draw bacteriostatic water with a syringe
  4. 4Inject diluent into the powder vial
  5. 5Roll (do not shake) to reconstitute
  6. 6Calculate concentration per mL from compound mg and water volume
  7. 7Re-draw the reconstituted solution with a fresh syringe
  8. 8Estimate dose volume from your hand-calculated concentration
  9. 9Inject
  10. 10Refrigerate the open vial · use within ~28 days

Each step is a place an error can enter — concentration math, sterile technique, or contamination of an open vial.

Aevum Cartridge Workflow
5 steps · ~60 sec
  1. 1Open the box · refrigerate the cartridge
  2. 2Click the cartridge into the Aevum injector pen
  3. 3Dial the click count printed on your protocol card
  4. 4Inject
  5. 5Return the pen to the fridge

No reconstitution, no concentration math, no open vial sitting in the fridge for a month.

Description

PT-141 (Bremelanotide) is a synthetic cyclic 7-amino-acid melanocortin-receptor agonist with selectivity for the MC4 receptor. Studied in published research.

What's in the Box
  • 1 × pre-filled 3 mL cartridge. Ready to use: no reconstitution, no mixing.
  • Small starter pack of pen needles. For restocking, any standard pen needle (4–8 mm, 31–32 gauge) fits the pen. Single-use consumables: a needle is not reusable.
  • Cold-chain insulated packaging with phase-change cold packs.
  • Quick-start pen guide.
  • First-time customers: reusable Aevum pen included free with your first order (normally $35 CAD).
Cartridge & Pen Specification

Aevum cartridges drop into the reusable Aevum pen. Each cartridge is metered into 240 increments. The pen dial advances one increment per click, so every60 clicks equals a quarter cartridge.

Figures describe the metering of the instrument. Aevum Labs does not recommend quantities or schedules for any application.
  • Load. Slide the cartridge into the pen barrel, screw on the cap, and prime with 2 clicks until a bead forms at the tip.
  • Meter. Turn the ring to the required increment count. The pen advances and clicks audibly per increment.
  • Store. Return the pen with cartridge to 2–8 °C between uses. Use the cartridge within 60 days of first pierce.

Storage & Handling
  • Unopened: refrigerate at 2–8 °C. Stable until the use-by date printed on the carton.
  • After first pierce: keep refrigerated at 2–8 °C and use within 60 days. Discard any cartridge past day 60 even if it looks unchanged.
  • Never freeze. Freeze-thaw cycles damage peptide structure irreversibly.
  • Protect from light. Store the cartridge in its foil sleeve when not loaded into the pen.
  • Travel: a cooler with a frozen gel pack (not in direct contact with the cartridge) keeps it safe for up to 24 hours.
Testing & Release

Every Aevum lot undergoes third-party HPLC and mass spectrometry analysis for identity and purity before release. Lots that fail specification are not released.

Each cartridge is marked with a unique lot identifier traceable to its release record.

COA matched the cartridge lot

Verified

Verified the third-party report against the lot number and it lined up exactly. Clear solution, sealed cleanly. Straightforward to confirm what I received.

Finished cartridge, no prep

Verified

No reconstitution and no concentration math. It arrives ready in the cartridge and clicks into the pen. A far cleaner handling process than the old powder-and-water routine.

Pen dispenses a precise amount

Verified

The click-to-dose pen keeps the per-click volume consistent across the whole cartridge. Much more repeatable than drawing from a vial by hand.

Cold-chain done properly

Verified

Gel packs frozen solid on arrival and the cartridge cool to the touch. The insulated box is clearly engineered to hold the cold chain for the full transit.
