Question 1

How do I convert micrograms (mcg) to milligrams (mg)?

Accepted Answer

To convert mcg to mg, divide by 1,000. Example: 250 mcg ÷ 1,000 = 0.25 mg. Conversely, multiply mg by 1,000 to convert to mcg.

Question 2

What is an International Unit (IU)?

Accepted Answer

An International Unit (IU) measures biological activity rather than physical mass. Because activity per mg varies by compound, IU-to-mass conversions require a compound-specific factor (e.g., standard HCG baseline is 1,000 IU per 1 mg).

Question 3

Why do peptides use both mcg and mg units?

Accepted Answer

Potent compounds (like BPC-157 or Semax) are dosed in microgram quantities (mcg) to prevent overdose errors, whereas larger compounds or vial contents are measured in milligrams (mg).
