Dilute acetic acid (typically 0.1–0.6% w/v in sterile water) is used as an alternative reconstitution diluent for a small number of hydrophobic or aggregation-prone research peptides — most commonly BPC-157 and TB-500 — that do not dissolve cleanly in plain bacteriostatic water at pH ~5.7.[1][2] **It is a diluent, not an active research compound — it has no peptide-like mechanism of action and is included in the registry only because it appears in the calculator inventory as an alternative reconstitution solvent for specific hydrophobic peptides.**
Dilute acetic acid lowers the pH of the reconstitution solvent below the isoelectric point of certain hydrophobic peptides, increasing their net positive charge and improving solubility.[2] Once the peptide is solubilised, the small volume of acetic acid co-administered subcutaneously with the peptide is below the threshold for local tissue irritation in typical research protocols. Glacial acetic acid is the parent reagent; the diluent used for peptide reconstitution is its dilute (0.1–0.6%) sterile aqueous form.
Dilute acetic acid as a peptide reconstitution diluent is not a separate FDA-regulated drug product — it is a research-protocol solvent. The strongest published precedent for using dilute acetic acid as a reconstitution diluent for BPC-157 and similar hydrophobic peptides comes from the protocols published by the Sikiric group (the originating BPC-157 research lab) and from peptide-synthesis vendor reconstitution guidance.[1][2] Bacteriostatic water remains the default reconstitution diluent for most peptides; dilute acetic acid is the specialty alternative when a peptide will not dissolve cleanly in BWFI.
Glacial acetic acid is FDA-recognised as a USP-grade reagent. Dilute (0.1–0.6%) acetic acid as a research-peptide reconstitution diluent is not itself a separate FDA-approved drug product. Used only as a research-protocol solvent for specific hydrophobic peptides; not itself an active research compound.
It is catalogued under Other Peptides on WPA.
The WPA community has not yet logged enough Acetic Acid calculator sessions to publish dose, vial size, or bacteriostatic water distributions for it. This page therefore covers what is known about the compound itself; the usage charts fill in as researchers run the calculator.
These figures come from anonymized WPA peptide calculator sessions, not verified administrations or unique people. Separate modal inputs do not establish a joint protocol. They are community input statistics — not dosing recommendations, and not medical advice.
