First Start: A Guide to Your Research Journey
Peptide Research, Explained Clearly
Peptides Research is an educational resource covering peptide science, reconstitution, concentration calculations, research protocols, storage and laboratory handling.
Explore straightforward guides designed to help you understand how peptides are studied, prepared and measured in research environments.
Educational and research-reference information only. Not medical advice.
1. Reconstitution: Preparing Your Peptide
Most research peptides arrive in a "lyophilized" (freeze-dried) powder form to ensure stability and shelf life. Before use, they must be reconstituted with Bacteriostatic Water (BAC).
The Step-by-Step Process:
-
Sanitize: Wipe the rubber stoppers of both your peptide vial and the BAC water vial with an alcohol swab.
-
Draw Water: Using a sterile syringe, draw the required amount of BAC water (commonly 3ml, depending on your preferred concentration).
-
The Gentle Tilt: Insert the needle into the peptide vial. Aim the needle at the side glass wall of the vial rather than spraying directly onto the powder. Let the water dribble down slowly.
-
Dissolve: Do not shake the vial. Shaking can damage the delicate peptide chains. Instead, gently swirl the vial between your palms or leave it to sit until the liquid is completely clear.
-
Store: Once reconstituted, most peptides must be kept refrigerated at 2°C – 8°C.
You will find specific information on each peptide reconstitution process on the peptide research page on the link below
2. Measuring Your Dose
There are two primary ways to measure your research solution:
A. Using a 100-Unit Insulin Syringe
Standard insulin syringes are measured in "units," where 100 units = 1mL.
-
If you added 1mL of water to your vial, then 10 units on the syringe equals 1/10th of the total vial content.
-
If you added 2mL of water, then 10 units on the syringe equals 1/20th of the total vial content.
Note: Always double-check your math. The "unit" is a measurement of volume, not the milligram (mg) strength of the peptide itself.
B. Using a Reusable Click-Pen
General insulin pen instructions
-
Wash your hands and gather the pen, a new pen needle, and a sharps container.
-
Attach a new needle securely. Use a new needle each time, then remove and discard it after use. Store the pen without a needle attached afterward.
-
Dial the prescribed number of units. Be careful to turn the dose selector and not accidentally press the injection button while dialing.
-
Choose an injection site recommended for subcutaneous insulin, commonly the abdomen, thigh, buttock, or back of the upper arm, and rotate sites rather than using the exact same spot each time.
-
Insert the needle as instructed for the pen and press the injection button slowly and fully.
-
Keep the needle in place briefly after pressing the button so the full dose is delivered. Follow the timing given for the specific pen.
-
Remove the needle, take it off the pen safely, and place it in a sharps container. Then recap the pen if applicable and store it according to the product instructions.
-
Store the pen correctly. Keep it away from direct heat and sunlight and do not let it freeze. Storage rules may differ between unopened and in-use pens.
Important safety notes
-
Never share an insulin pen with anyone.
-
Do not guess doses or copy someone else’s schedule; insulin dosing is individualized.
-
Keep some quick-acting sugar available in case of low blood sugar if insulin has been prescribed for regular use.
3. Subcutaneous (SubQ) Injection Guide
Subcutaneous injections are administered into the fatty tissue layer just below the skin and above the muscle. This method allows for a slow, consistent absorption of the compound.
Recommended Injection Sites
The goal is to find an area with a sufficient "pinch" of fat. Common sites include:
-
Abdomen: At least 2 inches away from the belly button. This is often the preferred site due to ease of access.
-
Outer Thighs: The fleshy part of the upper, outer thigh.
-
Back of Upper Arms: The fatty area behind the tricep.
The Injection Process
-
Sanitize: Clean the chosen site with an alcohol prep pad and allow it to air dry for a few seconds.
-
Pinch: Use your thumb and forefinger to gently pinch a 1-to-2-inch fold of skin and fat. This pulls the tissue away from the underlying muscle.
-
Insert: Hold the syringe or pen like a dart. Insert the needle quickly at a 45 to 90-degree angle to the skin.
-
Inject: Depress the plunger slowly and steadily until the full dose is delivered.
-
Withdraw: Pull the needle straight out at the same angle it was inserted.
-
Aftercare: If there is a tiny bead of blood, apply light pressure with a cotton ball or gauze. Do not rub the area, as this can cause bruising.
Pro Tip: Rotate your sites. Do not inject into the exact same spot every time. Moving the site by at least an inch each session helps prevent "lipohypertrophy" (the buildup of hardened fatty tissue) and ensures optimal absorption.
4. Finding Specific Dosing Data
Because every compound has a different concentration and research goal, we provide detailed protocols for every peptide in our catalog.
For specific reconstitution ratios, MG-to-Unit conversions, and suggested research protocols, please visit our dedicated research hub:
Important Safety Reminders
-
Never reuse needles. Always use a fresh, sterile needle for every draw.
-
Discard Safely: Use a designated sharps container for all used needles and pens.
-
Inspection: If the solution remains cloudy or contains visible "floaters" after sitting, do not use it and contact support.
