Overview

Prostamax sits within the family of tissue-directed short peptides investigated in organotypic tissue culture. Available research examined tissue-specific effects of synthetic peptide bioregulators in cultures taken from young and old rats, and the broader role of short peptides in cell differentiation.

The compound-specific literature is thin. Researchers should treat the class-level literature as background rather than as evidence about this sequence in isolation.

History

Prostamax arises from the Russian peptide-bioregulator programme, which paired tissue extracts with defined synthetic short-peptide analogues intended to reproduce their activity.

Published investigation has remained largely confined to organotypic culture studies.

Key Research Areas

Research relevant to Prostamax centers on tissue-specific short-peptide activity in organotypic culture and on peptide regulation of cell differentiation. Reference support is thin relative to better-characterized compounds.

4 of the 4 areas below are addressed directly by a paper cited on this page.

Organotypic tissue-culture models

Addressed on this page by Zakutskiĭ 2006. Each is linked to its source record in the references below, so what was measured — and in what system — can be read rather than taken on trust.

Age-comparative culture studies

Addressed on this page by Zakutskiĭ 2006. Each is linked to its source record in the references below, so what was measured — and in what system — can be read rather than taken on trust.

  • Zakutskiĭ, AN. et al. (2006) — The tissue-specific effect of synthetic peptides-biologic regulators in organotypic tissues culture in young and old rats

The references section of this page cites 2 primary papers published between 2006 and 2020 — a thin record. Every citation is linked to its PubMed or DOI record so it can be read rather than taken on trust, and the summaries above describe what those papers report rather than what the compound is claimed to do.

Research compounds attract claims that outrun their evidence. Below are the ones most often encountered for Prostamax, set against what the papers cited on this page actually report. Where the record is thin or contested, that is stated rather than smoothed over.

Preclinical only

Prostamax is commonly described online in connection with faster healing from injury and improved recovery. In the research literature the same compound is filed under organotypic tissue-culture models, tissue-directed bioregulator research and peptide-regulated cell differentiation.

The 2 papers cited on this page, published between 2006 and 2020 (1 in animal models) describe laboratory and animal work. None reports a controlled trial in humans. Findings in cell culture or in a rodent model describe what happened in that system; they do not establish that the same occurs in humans, and this compound is not approved for human use.

Not supported

Presented alongside compounds with decades of published research, as though the evidence base is comparable.

It is not. Prostamax rests on 2 cited papers (between 2006 and 2020). A record that thin cannot support conclusions about mechanism, effect or safety, and the honest reading is that this compound has been studied very little rather than studied and validated.

Nothing above is a statement of what this material does. It is a summary of what has been published and what has not. Eppix Labs supplies research materials only and provides no dosing, administration or protocol guidance.

Verification for Prostamax is per lot, not per product. The current 20mg lot PROS-CA-26H-20 returned 99.603% purity, 22.15 mg measured, 110.8% of the labelled 20 mg, assayed by Janoshik. Those figures are the laboratory's, published in full rather than reduced to a badge.

Purity is half the number. It states what fraction of the material in the vial is Prostamax; it says nothing about how much material is in the vial, and a short-filled vial can return a purity result that is entirely accurate. The figure that answers the second question is measured mass against expected content — for Prostamax, this lot measured 110.8% of its labelled 20 mg. Both numbers are published for every lot, whichever way they fall.

The lot code printed on the vial matches the code on the certificate for Prostamax. Matching the two is what confirms the unit in hand came from the batch that was tested — a certificate not tied to a lot code proves nothing about any particular unit.

Researchers who buy Prostamax in Canada through Eppix Labs receive the lot described by the certificate above: the code printed on the vial label is the code on the certificate, and both are searchable on the batch verification page.

Format
Lyophilized powder

Prostamax is supplied as lyophilized powder. In the dry state the material is comparatively stable, which is why it ships at ambient temperature without a cold chain; once reconstituted it is a peptide in solution and the handling constraints tighten considerably. At 4 residues it is short enough to be produced by solid-phase synthesis, and the published sequence on this page is what an identity assay is checked against.

Repeated freeze-thaw cycling is the handling error most likely to degrade material of this class, because each cycle concentrates solutes at the ice boundary. Where a protocol calls for the same vial across multiple sessions, the published literature generally describes aliquoting after reconstitution rather than re-freezing the whole volume.

Vials may appear empty on arrival. Lyophilized material collects at the base of the vial and is often not visible until the vial is inspected under direct light.

  • 1 × sealed glass vial in the strength selected (20mg / Single Vial, 20mg / 5-Pack, 20mg / 10-Pack available), batch-labelled
  • The batch-linked Certificate of Analysis for the exact lot shipped
  • Discreet outer packaging with no product names on the exterior
  • Canada Post Xpresspost, tracked, typically 1–2 business days from Canadian stock
Not included
  • Bacteriostatic water or any other reconstitution vehicle
  • Syringes, needles or filters
  • Dosing, administration or protocol guidance of any kind

Reconstitution materials are sourced separately. The reconstitution calculator on this site works out concentrations for a given volume, but it is an arithmetic tool for laboratory record-keeping and not a protocol.

No. Eppix Labs products are supplied exclusively for laboratory research. We do not provide dosing, administration, or usage guidance.

Each unit contains the labeled quantity of Prostamax. Independent third-party analysis verifies purity, identity, and net content per batch.

The unit contains only the research compound. Any laboratory materials required for reconstitution or experimental procedures must be sourced separately.

Duration depends entirely on research design, storage conditions, and laboratory protocol.
