BPC-157 - Xeno Laboratories

Buy BPC-157 by Xeno Labs at XSteroids. BPC-157 is the synthetic pentadecapeptide that the research literature calls Body Protection Compound 157, and Xeno Labs ships it as a lyophilised powder in a single glass vial. This page sets out what the vial is, how the peptide behaves in animal studies, what the published doses look like, how to mix the powder and read a U-100 syringe, and where the legal and anti-doping lines sit.

Two caveats shape everything that follows. There is no licensed medicine form of BPC-157, and the compound appears in the WADA S0 category as an illustration of a substance with no medical use. None of the material below is clinical advice; every number is taken from research papers and none of it is a programme for a human being.

What the Xeno BPC-157 Vial Is and What You Are Buying

What arrives is a single small glass vial of white lyophilised powder. The peptide name sits on the pack, and the product is filed in the repair peptide category beside the cognitive and longevity vials of the same line. No filler list accompanies it, no third party assay of the contents has ever been published, and only one strength is catalogued, so the shop page reproduces the label as written instead of asserting a verified mass.

The molecule itself is a short chain of fifteen amino acids, sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, formula C62H98N16O22 and a mass of about 1419.56 g/mol. It is a fragment of a protein found in gastric juice, not a steroid, not a hormone and not a growth factor: it is a peptide, and it has to be dissolved before any research use.

How BPC-157 Is Thought to Work in Research

The consistent findings in animal work are cytoprotection, faster healing of experimental tissue injuries, new blood vessel formation and a drop in pro-inflammatory cytokines. Several papers also describe increased expression of the growth hormone receptor and of signalling paths tied to angiogenesis. Those effects were recorded in rats, mice and, in pharmacokinetic work, dogs.

Pharmacokinetics in animals move quickly. After intramuscular and intravenous dosing in rats, the reported half-life falls between 7.9 and 30 minutes, while absolute intramuscular bioavailability came out at 45 to 51 percent in dogs and 14 to 19 percent in rats, with urine and bile clearing the peptide. Stability is the surprise: a molecule this small survives human gastric juice intact for over a day and remains stable in urine for four days, which is why the literature keeps returning to the oral versus injection question.

What to Expect from a BPC-157 Research Protocol

Expect a short-lived compound. With a half-life measured in minutes, single-dose blood levels clear long before the day is over, and the animal studies that report tissue effects used repeated administration over days or weeks, not one shot. A single injection will not hold a level.

Expect the evidence to be preclinical. A systematic review screened 544 papers and included 36 studies: 35 of them were animal or laboratory work and only one was a clinical study. For a buyer that matters more than any single headline result, because the human safety profile has not been characterised in the way a licensed medicine is.

Dosing and Reconstitution of a BPC-157 Vial

The arithmetic is the same for every lyophilised peptide. Concentration equals the milligrams in the vial divided by the millilitres of water added, and one unit on an insulin syringe marked U-100 is 0.01 ml. Choose the water volume so that the reading on the syringe lands on a comfortable mark.

Worked Examples

A 5 mg vial with 2 ml of bacteriostatic water gives 2.5 mg/ml, so 0.1 ml is 250 mcg and reads as 10 units. The same 5 mg with 5 ml gives 1 mg/ml, so 0.1 ml is 100 mcg and reads as 10 units. A 10 mg vial with 2 ml gives 5 mg/ml, so 0.1 ml is 500 mcg and reads as 10 units. The strength of this Xeno vial is printed on the pack; use that number in the same formula.

Published Amounts

Published animal work uses microgram amounts per kilogram, which is why low microgram readings are normal in this field. Higher numbers are not better: the studies that report effects report repeated small doses.

Stacking BPC-157 With Other Repair Research Vials

In the literature the peptide is usually studied alone. Buyers often pair it with other repair work: Semax for the neurological side of recovery research and Selank for the calm-focus side. Longevity work is covered by Epitalon, and the metabolic pair of Semaglutide and Tirzepatide is the third shelf of the same catalog.

Hormonal recovery is separate. Where a cycle has suppressed natural production, HCG 5000 IU and HMG 75 IU belong to that discussion, and Tamox belongs to the SERM side of it. Nothing in this paragraph is a recommendation to combine anything.

Break Periods and Recovery After BPC-157 Research

Because human pharmacokinetics are not established, there is no validated washout figure to quote. The practical research approach is to treat each vial as one short block, keep notes on what was given and when, and leave a gap between blocks rather than running one continuously.

Recovery in this context means the body's own healing, not restarting a suppressed axis: BPC-157 is not suppressive and does not require a post-cycle protocol. If a research block sits inside a steroid cycle, the recovery plan is about the steroids, and the SERM and HCG cards in this catalog cover that side.

BPC-157 Side Effects, Evidence and Legal Standing

There is no human safety dataset large enough to describe a side effect profile, because there is almost no human data at all. Reported animal findings are generally uneventful, but absent human data is not the same as a clean record, and the 2025 review that examined the evidence base pointed at exactly that gap.

Regulatory status is the hard line: there is no licensed medicine form of it. Anti-doping status is equally clear: the peptide has been prohibited since 2022 under the WADA S0 class, the catch-all category, and the 2026 list names BPC-157 as an example. A therapeutic use exemption is unrealistic for a substance with no licensed indication. This vial is a research product only.

Storage of the BPC-157 Vial

The dry vial wants either refrigeration at 2 to 8 C or a stable room temperature between 15 and 25 C, always shielded from light, and the powder itself must never enter a freezer. After water is added the solution belongs in the fridge and should be finished inside 28 to 30 days, with freeze-thaw cycles avoided because each one damages peptide. Store it standing upright, somewhere nobody could take it for ordinary medicine.

Why Buy BPC-157 from XSteroids?

This vial occupies one page of the Xeno Labs catalog at XSteroids, and every other shelf of the line sits behind it, so a single order can gather the repair, cognitive, longevity and metabolic entries at once. Payment goes through an encrypted checkout; a US parcel typically lands within 3 to 6 days and an international shipment within 12 to 26. Cards below list what buyers usually add alongside it.
