Peptide Tools
Calculate your exact dose, learn proper reconstitution, and master subcutaneous injection technique. Everything a new or experienced peptide user needs in one place.
Enter your vial size, how much bacteriostatic water you used, and your target dose. The calculator will tell you exactly how many units to draw.
Recommended needle setup
Follow these steps every time you reconstitute. Proper mixing technique protects the peptide from degradation.
Lyophilized peptides come as a white powder. Store unreconstituted vials in the freezer. Never shake the vial.
Use bacteriostatic water only, never regular saline or tap water. Draw slowly from the BAC water vial with a clean syringe.
Aim the stream down the inside wall of the vial. Never inject directly onto the powder. Let it dissolve on its own, do not shake.
Gently rotate the vial between your fingers until fully dissolved. The solution should be clear and colorless. If cloudy, discard.
Four steps for a clean, accurate, and comfortable subcutaneous injection every time.
Wash hands thoroughly with soap for 20 seconds. Clean the injection site and vial top with separate alcohol swabs. Let both dry completely before proceeding.
Insert the 31G needle through the center of the vial stopper at a slight angle. Draw back slowly to your calculated unit number. Hold syringe needle-up and flick to move bubbles to the top. Push slightly to expel air.
Pinch 1-2 inches of skin firmly. Insert the 5/16 inch needle at a 45-degree angle in one smooth motion. Release the pinch. Depress the plunger slowly over 5-10 seconds.
Withdraw the needle at the same angle it entered. Press a clean alcohol swab gently on the site for 10 seconds. Do not rub. Dispose of the needle in a sharps container immediately.
Rotating injection sites prevents lipodystrophy and improves absorption over time.
2 inches from your navel on either side. The most common and accessible site. Easy to pinch. Rotate left and right sides with each dose.
The middle outer portion of your upper thigh. Easy to reach without assistance. A good alternative when abdomen sites need rest.
The back of your upper arm. Requires more flexibility to reach solo. Effective as a third rotation point for multiple daily doses.
Small technique differences have a large impact on safety, absorption, and comfort.
Proper storage is critical. Heat and light degrade peptides. Cold and dark preserves them.
Store in the freezer at -4F to -20F. Keep away from light. Can last 12-24 months frozen. Do not freeze-thaw repeatedly.
Store in the refrigerator at 35-46F. Keep away from light. Use within 30 days. Never freeze a reconstituted vial.
Keep in an insulated cooler with an ice pack. Never leave in a hot car. If left at room temperature, use within 24-48 hours or discard.
Answers to the questions that come up most often when starting a peptide protocol.
Bacteriostatic water contains 0.9% benzyl alcohol which prevents bacterial growth, making it safe for multi-dose use. Regular sterile water has no preservative and should only be used for single-dose vials.
A compromised peptide may appear cloudy, have visible particles, or have an unusual smell. A properly reconstituted peptide should be completely clear and colorless. When in doubt, discard.
Minor redness and swelling at the injection site is normal and should resolve within 30-60 minutes. Persistent swelling, heat, or pain lasting more than a few hours may indicate an infection. Consult a healthcare provider if concerned.
Some peptides can be combined in a single injection. BPC-157 and TB-500 are commonly stacked together. Always research specific combinations before mixing. When in doubt, inject separately.
Subcutaneous (SubQ) injections go into the fat layer just under the skin using a short fine needle at 45 degrees. Intramuscular (IM) injections go into muscle using a longer needle at 90 degrees. Most peptides are administered SubQ.
Never put used needles in regular trash. Use an FDA-cleared sharps disposal container. Many pharmacies and hospitals accept full sharps containers for safe disposal. Never recap a used needle.
