This guide describes standard laboratory reconstitution and handling procedures intended for in vitro research applications only. All protocols are provided for scientific reference. Products referenced are not approved for human or animal use.

Most lyophilized research peptides arrive as a dry white powder sealed inside a small glass vial. That powder is stable, easy to ship, and can sit at room temperature for months — but it can't be used in research protocols until it's dissolved into a liquid solution.

Reconstitution just means adding liquid to the powder to turn it into a solution. Once dissolved, the compound can be precisely measured and prepared for in vitro laboratory use.

What You'll Need

• Bacteriostatic Water (BAC Water) — the standard solvent for peptide reconstitution. A 30mL vial is enough for multiple reconstitutions.
• Draw syringe — 3mL with 18G needle, for transferring BAC Water into the peptide vial.
• Measurement syringe — 1mL U-100 with 31G needle, for accurately measuring your reconstituted solution.
• Alcohol prep swabs — standard isopropyl, for wiping vial tops before any needle insertion.
• A clean, flat surface — wipe it down before you start.

Why BAC Water and not regular water? BAC Water contains 0.9% benzyl alcohol, which prevents bacterial growth after the vial has been opened. Plain sterile water becomes contaminated within hours of first use. BAC Water keeps your reconstituted solution stable for 4–6 weeks when refrigerated. Do not substitute tap water, distilled water, or saline.

Step-by-Step Process

Step 1 — Wipe both vials

Use an alcohol swab to clean the rubber stopper on both the peptide vial and the BAC Water vial. Let them air dry for a few seconds.

Step 2 — Draw your BAC Water

Insert the needle into the BAC Water vial and pull back the plunger to draw the amount you need (see the concentration math below). Go slow — no need to rush.

Step 3 — Add the water slowly

Insert the needle into the peptide vial and angle it so the BAC Water runs down the side of the vial, not directly onto the powder. Slowly depress the plunger. Direct pressure on the powder can degrade the compound.

Step 4 — Swirl, don't shake

Once the liquid is in, gently swirl the vial in a slow circular motion until the powder is fully dissolved. The solution should be clear. Do not shake — shaking can break down the peptide structure.

Step 5 — Inspect

Hold the vial up to light. The solution should be clear and free of floating particles. If it's cloudy or has visible chunks, it hasn't fully dissolved — keep swirling gently.

Concentration Math

The formula: mg of peptide ÷ mL of BAC Water added = mg/mL concentration

Example: You have a 3mg peptide vial and add 1mL of BAC Water. 3mg ÷ 1mL = 3mg/mL — every 0.1mL (10 units on an insulin syringe) contains 0.3mg.

Magnolia RL Product Reference (2mg Vials)

Retatrutide and CJC-1295 No DAC are both supplied as 2mg lyophilized vials. Use this table to find your working concentration based on how much BAC Water you add.

Recommended starting point: Add 2mL of BAC Water to a 2mg vial → 1mg/mL. This gives you clean round numbers on a U-100 insulin syringe: 10 units = 100mcg, 20 units = 200mcg.

Storage After Reconstitution

• Store reconstituted vials in the refrigerator (2–8°C / 36–46°F)
• Keep away from light — store in a drawer or box if possible
• Use within 4–6 weeks of reconstitution
• Do not freeze a reconstituted solution — freeze-thaw cycles degrade the compound
• Unreconstituted (dry powder) vials can be stored at −20°C long-term

Quick Reference

Common Mistakes to Avoid

• Shaking the vial. Shaking introduces air bubbles and can mechanically degrade peptide structure. Always swirl slowly.
• Injecting BAC Water directly onto the powder. Aim the needle so liquid runs down the glass wall. Direct force on the powder can cause incomplete dissolution or degradation.
• Using the wrong syringe to measure. A 3mL draw syringe is fine for transferring BAC Water into the vial. For measuring your final dose, always use a 1mL U-100 insulin syringe.
• Storing reconstituted vials at room temperature. Once mixed, refrigerate immediately at 2–8°C.
• Freezing a reconstituted vial. Freeze-thaw cycles denature peptide bonds. If you won't use a reconstituted vial within 6 weeks, discard it and reconstitute fresh powder.
• Not swabbing with alcohol before every draw. Each needle insertion is a contamination risk. Wipe the rubber stopper every time.
