— Reconstitution & technique guide

Sealed vial to ready solution.

Six steps, one diagram each. Aseptic technique that won't denature your peptide. For research use — this guide is not a recommendation to dose any human or animal subject.

Prescription telehealth.If you are reconstituting a compound intended for human use, that material must come from a licensed compounding pharmacy under a valid prescription — not from a research-supply company.

What you'll need.

— Compound
Lyo vial

Sealed, refrigerated. Inspect cake for clarity and absence of cracks.

— Diluent
BAC water

Bacteriostatic water (0.9% benzyl alcohol). USP-grade, Rx.

— Draw
3 ml syringe

Slip-tip preferred. 21G needle for the draw, swap to 27–30G for use.

— Disinfect
Alcohol swabs

70% isopropyl, individually packaged. One per puncture.

— Surface
Clean tray

Plastic or stainless. Wipe with isopropyl, let dry 30 seconds.

— Track
Sharpie + log

Date the cap with reconstitution date. Note volume in your log.

— Step by step

Six steps. Two minutes, end to end.

01

Bring vial to room temp.

Pull the lyo vial from the fridge 10–15 minutes before reconstituting. Cold glass + cold BAC water can crack a stopper or shock the cake.

Why: warm reconstitution dissolves more cleanly and avoids stopper failure. Rushing here is the most common newbie error.

02

Swab both stoppers.

Pop the plastic flip-cap. Swab the lyo vial stopper and the BAC water stopper with separate alcohol pads. Let air-dry 10 seconds — wet alcohol on the stopper transfers into your draw.

One swab per puncture. Don't reuse — that's how you carry skin flora into the vial.

03

Draw BAC water.

Pull air into the syringe equal to the volume you want — typical 2.0 ml. Insert into BAC vial, push the air in (this equalises pressure), then invert and draw your 2.0 ml. Tap to dislodge bubbles, push them back into the vial.

Volume: match the volume on the dosing-calculator page for your dose. Common defaults: 2.0 ml for GLP-1 family, 3.0 ml for BPC/TB.

04

Slow stream down the vial wall.

Pierce the lyo vial. Angle the needle so the BAC water runs down the inside wall — do not squirt directly onto the cake. The cake should dissolve in seconds without foaming.

Foaming = aggregation risk. Foam means the water hit the cake too fast. Tilt the vial to ~30° and let it run.

05

Swirl, don't shake.

Gently swirl in your palm for 30 seconds. The solution should clarify completely — no haze, no particulates. If anything floats or settles, do not use; contact us.

Vortexing is fine for GLP-1 family but not for the regenerative peptides (BPC, TB). When unsure, swirl.

Date, label, refrigerate.

Sharpie the reconstitution date on the cap. Store upright on a back shelf of the fridge — not the door. The 28-day clock starts now.

Cross-check the per-compound shelf life on the storage guide — KPV and GHK-Cu we cap at 14 days.

Reconstitution variants.

— Variant A · Single-dose

Single-use reconstitution

  1. Use sterile water (no preservative) — for one-time use only, no benzyl alcohol needed.
  2. Reconstitute the full vial. Smaller volume (typically 1.0 ml) for a more concentrated solution.
  3. Use within 4 hours of mixing. No multi-day storage.
  4. Discard the vial after the single use; do not re-pierce or refrigerate.

— Variant B · High-volume multi-dose

Larger-volume multi-dose

  1. BAC water, 3.0–5.0 ml. Larger volume = more dilute solution = lower concentration per unit.
  2. Pre-calculate units per dose. Use the dosing calculator before reconstituting so you know how the syringe markings map to your dose.
  3. Limit punctures to ≤ 20. Track on the cap with tally marks; replace earlier if stopper looks worn.
  4. Rotate vials weekly if running multiple compounds — pierces add up faster than people think.

Troubleshooting matrix.

— Cake won't dissolve

Slow dissolution.

Add 30 seconds of slow swirl. If still cloudy after 2 minutes, the vial may be too cold — let warm to room temp and retry. Do not vortex regenerative peptides.

— Foaming

Excessive foam on top.

Caused by injecting BAC water too fast or shaking. Foam aggregates protein. Let the vial rest 5 minutes; if foam remains, return for replacement.

— Cloudy / particulates

Visible particles.

Stop. Do not use. Photograph the vial and email support@elementmd.com with your lot number — we replace under the guarantee.

— Pressure issue

Vial creates vacuum.

Normal at first puncture. Add 0.2 ml of air before drawing solution. If pressure persists, the stopper may be compromised — discard.

— Stopper coring

Rubber bits in solution.

Rare but possible after 15+ punctures. Filter through 0.22 µm before next use, and replace vial. Use a fresh stopper position for each puncture.

— Color shift

Yellow / pink tint.

GHK-Cu is naturally blue when reconstituted; that is expected. Other peptides should be colorless. Tint = oxidation. Discard.
