Prostamax at a glance

Prostamax, abbreviated KEDP after its four residues, is a synthetic tetrapeptide from the St. Petersburg bioregulator program led by Vladimir Khavinson. The group's earlier work with prostate-derived extracts, including a preparation known as Prostatilen, preceded the design of this short synthetic sequence. It is supplied as lyophilized powder for laboratory use. Its small, defined structure makes it far easier to characterize than the tissue extracts that came before it, which helps when reviewing batch documentation.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

What it is studied for

Like related bioregulators, Prostamax is proposed to act inside the cell rather than through a surface receptor. Studies from its developers report that the peptide promotes decondensation of heterochromatin in lymphocytes from older donors, a change associated with renewed transcription of genes silenced with age, and some work describes effects on markers of cellular aging in culture. Prostate specificity is assumed from its design origins rather than demonstrated, and independent groups have not mapped a binding target or confirmed the mechanism.

Research and regulatory status

Published data consist of cell-culture and animal studies, most from the originating research network and its partners. No controlled clinical trial has been reported, and Prostamax is not an approved medicine. It is best regarded as an exploratory compound within the aging and epigenetics corner of bioregulator research. GLP1 Forum Escrow lists it for laboratory use only, and buyers should depend on independent testing to confirm identity rather than on label descriptions.

Checking the lab data

Mass spectrometry should show a mass consistent with Lys-Glu-Asp-Pro, and because rearrangements of the same four residues share an identical mass, a lab that can supply MS/MS fragmentation or another sequence check adds real value. HPLC purity should be reported with a chromatogram from a method suited to a short, polar peptide. Expect net content, salt form, a white lyophilized appearance and batch traceability.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 20 mg vial dissolved in 2 mL gives 10 mg/mL, or 20 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

What does decondensation of heterochromatin mean?

Heterochromatin is tightly packed DNA where genes are usually switched off, and with age some regions become more condensed. Decondensation means loosening that packing, which can make genes accessible again. Bioregulator researchers measure it as a marker of their proposed effect, though such changes alone do not demonstrate a functional outcome in tissue.

Why is Prostamax considered tissue-specific if its target is unknown?

The label comes from the design rationale: the sequence was chosen based on research with prostate-derived preparations, and the bioregulator model assumes short peptides act preferentially in their tissue of origin. Direct evidence for prostate selectivity is limited, so the description reflects the developers' framework more than confirmed pharmacology.

How much Prostamax is in this listing?

10 vials of 20mg each — 200 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does SSRBIO get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
