About PepSplain

Peptide math, without the science degree.

We want the calculations to be understandable—even if high school chemistry was not your favorite class.

Why PepSplain exists

People routinely confuse milligrams, micrograms, milliliters and syringe-scale markings. PepSplain tries to make those different measurements easier to understand by showing the formulas, examples, and a schematic animation instead of simply returning a mysterious number.

Our calculation interface has no recommendations for what substance someone should use or what amount is appropriate. Readers enter their own figures and see the corresponding arithmetic.

Ownership and commercial disclosure

PepSplain shares an owner with Driftless Research, a peptide business. The same owner is also developing Daily Peptide Stack, a separate news and research publication. PepSplain is a distinct educational site, but it should not be mistaken for having unrelated ownership.

There are currently no product listings, affiliate offers or checkout links in the calculator. If the editorial or commercial model changes, the disclosures on this page should be updated accordingly.

What PepSplain does and does not do

  • It does show reproducible, user-input arithmetic for mass, volume, concentration and labeled syringe-scale equivalents.
  • It does explain common unit differences and highlight some mathematical inconsistencies.
  • It does not confirm safety, legality, medical appropriateness, pharmaceutical status or product quality.
  • It does not replace professional instructions or determine what any person should administer.

Related project

Daily Peptide Stack is being developed as an editorial companion covering science, policy and research news. See how the two sites will connect.
