Peptide calculator — questions and answers
What does the peptide calculator calculate?
It calculates concentration and the volume corresponding to a reference amount you enter from a verified label or independently established protocol. It does not choose a dose.
What are U-100 syringe units?
U-100 is a volume scale: 100 markings represent 1 mL. These markings are not International Units (IU), milligrams or micrograms. Device accuracy is not verified.
Can IU be converted to mg?
Not generically. IU represents biological activity and the relationship to mass is substance- and product-specific. Use an IU basis only when the exact label states the total IU and verified final volume.
How do I calculate a blend?
Enter each ingredient mass and the verified final volume. The calculator shows each concentration separately and the other ingredients carried in the same volume; it does not recommend a blend dose.
Does the tool supply a recommended dose?
No. Dosing depends on the exact product, indication, formulation and patient. Many listed research compounds have no established evidence-based general human dose.
Is this medical advice?
No. It is arithmetic only, not medical advice or instructions for preparing or administering a product.
Safety: This is arithmetic only, not medical advice, a prescription, dosing guidance or a preparation guide. IU is not universally convertible to mg; U-100 markings represent volume. Product identity, active content, sterility and device accuracy are not verified. Do not use calculator outputs to self-administer investigational products.
