What is Prostamax?
Our molecular dataset records no CAS number, formula, molecular weight, sequence or residue count for this item, only the classification as a prostate peptide bioregulator complex. No chemistry values are quoted here that cannot be sourced. Preparations in this category consist of short peptide fractions rather than one synthetic sequence, so a per-lot analytical profile substitutes for a molecular formula.
The bioregulator concept comes from Vladimir Khavinson and colleagues at the St Petersburg Institute of Bioregulation and Gerontology. Their programme began with cytomedines, peptide fractions isolated from animal organs, and progressed to cytogens, short synthetic sequences chosen as minimal active fragments. The proposed mechanism is that very short peptides enter the nucleus and interact with promoter DNA or histones to alter transcription of genes associated with the source tissue.
That proposal remains a hypothesis. The evidence rests on docking simulations and spectroscopic binding studies from the originating group, no crystallographic structure of such a complex has been reported, and independent replication of the tissue-specific claims is limited. What is established is that preparations of this class are chemically simple, stable as dried solids, and characterizable by chromatographic profile even without a single molecular identity.
Reconstitution & handling
The material dissolves in bacteriostatic or sterile water introduced slowly down the vial wall, since short peptide fractions of this kind are freely water soluble. Concentration is the labeled milligram content divided by the diluent volume, expressed as total peptide rather than molarity, since no single molecular weight applies. Swirl gently until the cake clears.
Storage & stability
Sealed vials are stored at -20 degrees Celsius, shielded from light and moisture, since the cake is hygroscopic and a collapsed cake indicates seal failure. Reconstituted material is refrigerated at 2 to 8 degrees Celsius, divided into single-use aliquots, and kept away from repeated freeze-thaw cycles. Because this is a mixture rather than one molecule, a change in the chromatographic profile is a more sensitive stability indicator than appearance.
How it's tested
Analysis is by reverse-phase HPLC at 214 and 220 nanometres, and for a multi-component preparation the reported result is a chromatographic fingerprint compared against a reference profile rather than a single main-peak purity figure. Mass spectrometry characterizes the principal components. Net peptide content is measured so the labeled figure reflects peptide rather than counter-ion and water.
