Lyochem buyer fit
This Lyochem page is intentionally written for research labs, core facilities, and method-development teams qualifying PROSTAMAX Research Preparation as a reference-grade lot. It is not the pharmacy procurement owner for this SKU; the page should win differentiated searches around sequence verification, assay suitability, lot continuity, and data-packet depth.
Overview
PROSTAMAX is a trade-name preparation, generally offered as a prostate-directed short-peptide product in the upstream supplier-catalog space. It recurs mainly in Russian and Eastern European peptide-bioregulator catalogs, where organ-targeted reference-name preparations are an established commercial pattern overlapping the Khavinson bioregulator framework. Its composition is proprietary to the upstream manufacturer and is confirmed against the batch-specific COA prior to any order placement rather than inferred from the name. Lyochem carries PROSTAMAX to support research-buyer procurement built around upstream price references from the Russian-school bioregulator ecosystem. Where the underlying material is a prostate-tissue Khavinson peptide, direct end-buyers may prefer the named-molecule equivalents in the Khavinson family; alternatively, the regulatory team can provide explicit composition disclosure ahead of ordering. The standard 20 mg vial aligns with the format convention of the wider Khavinson catalog.
Applications & buyer fit
Khavinson short bioregulators — Admax, Cortagen, Cartalax, Cardiogen, Bronchogen, Crystagen, Prostamax, Vesugen — ship to research labs replicating Russian-school protocols or running comparative tissue-specific peptide-bioregulator studies. The published literature base for this class is concentrated in Russian-language sources; buyers should expect to consult that literature directly for protocol selection. Analytical-packet expectations are the same as any other lyophilised research peptide.
Contract Research Organisations (CROs)
CROs running preclinical and translational studies on behalf of academic, biotech, or pharma sponsors who need traceable reference material across multi-site campaigns.
Every release ships with its own batch-specific CoA — identity, purity, and the analytical scope agreed at quote stage, tied to the exact lot you receive.
Review a representative batch CoA before you order, so you can confirm the packet matches what your method or sponsor audit needs.
Supplied strictly as a research reagent to research institutions — not a finished dosage form and not for human administration. Buyer qualification runs at the inquiry stage.

Regulatory note
This is a reference-name product whose API identity has not been publicly disclosed; before any downstream research or regulatory use, its composition is set out on the batch-specific COA.
Frequently asked questions
We characterize what the material contains rather than certify a disclosed formula. RP-HPLC produces a fingerprint chromatogram of the preparation, showing whether it resolves as one dominant species or as the multi-component profile typical of tissue-derived extracts. Mass spectrometry reports the mass of the principal species so a receiving lab has a defined analytical handle even when the upstream recipe is undisclosed. For injectable-route work we add sterility and microbial-limits results. None of this substitutes for manufacturer composition disclosure, but it gives a reproducible batch signature that can be compared lot-to-lot and referenced in method records.
For an undefined or multi-peptide preparation, the HPLC trace itself becomes the consistency metric. Run under fixed gradient and column conditions, the retention positions and relative peak areas form a signature; a new lot that overlays the reference trace supports comparability, while shifted or new peaks flag a change in the upstream material. We supply the chromatogram and the dominant-species mass on each COA specifically so buyers can perform this overlay against their retained reference. This does not establish mechanistic equivalence to any named single-peptide product, but it does let a lab detect drift before it confounds downstream results.
