📖 How to Use This Tool
+
Most peptides can be stacked, but avoid mixing peptides with drastically different pH levels. BPC-157 + TB-500 is a popular combination. Always research compatibility before combining.
Draw the clearer peptide first. If both are equally clear, draw from the vial with higher concentration. This prevents cross-contamination and maintains sterility.
Yes. Before drawing from each vial, inject the same amount of air you plan to withdraw. This prevents vacuum formation and makes drawing easier.
Never. Draw each peptide separately into the same syringe. The mixing happens in the syringe, not in the vials.
No. Mix peptides immediately before injection. Pre-mixing can cause degradation and increases contamination risk. Draw fresh each time.
