BPC 157 - Axiolabs

Buy BPC 157 5 mg by Axiolabs at XSteroids. BPC 157 is a synthetic pentadecapeptide of 15 amino acids that comes from a protein found in human gastric juice, supplied here as a lyophilized 5 mg vial. It is one of the most written-about research peptides for tissue repair and also one of the least tested in people, so this page separates what studies show from what sellers claim. You will find the chemistry, how a 5 mg vial is mixed, research amounts, stacking, storage and legal status.

One framing note before the numbers: BPC 157 has no approved human dose and no approved indication, so every amount below is taken from research write-ups rather than from a label.

About BPC 157 by Axiolabs

The full name is Body Protection Compound 157, and the peptide is 15 amino acids long with a molecular mass of about 1419.6 g/mol. Its synonyms in the literature are bepecin, PL 14736 and gastric pentadecapeptide. Axiolabs supplies it as a lyophilized powder in a 5 mg vial that is mixed with bacteriostatic water before use.

Two physical facts matter at the bench. BPC 157 is stable at room temperature and survives in human gastric juice intact for more than 24 hours, which is unusual for a peptide and explains the interest in oral routes. Animal pharmacokinetics describe a short half-life of 7.9 to 30 minutes after intravenous or intramuscular dosing in rats, with excretion through urine and bile.

How BPC 157 Works

Preclinical models point to cytoprotective, neuroprotective and anti-inflammatory activity with faster healing of tissue. A 2025 systematic review gathered 544 publications and included 36 studies, of which 35 were preclinical and only one was clinical. It reports that BPC 157 raises growth hormone receptor expression, activates several cell growth and angiogenesis pathways, and lowers pro-inflammatory cytokines.

Human data remain thin. A retrospective series followed 12 patients with chronic knee pain who received 4 mg intra-articularly, and 11 of the 12 reported meaningful improvement. A Phase I study in healthy volunteers was run, but its results were never filed. Because the peptide promotes angiogenesis, a theoretical concern about tumour promotion exists and is explicitly listed as needing more study.

BPC 157 Dosage and Reconstitution

Mixing a 5 mg vial

Add 2 ml of bacteriostatic water to the 5 mg vial for a concentration of 2.5 mg/ml, which is 2500 mcg/ml; then 0.1 ml holds 250 mcg, equal to 10 units on a U-100 syringe. With 1 ml of water the concentration doubles and 0.1 ml holds 500 mcg. Swirl gently, never shake, and keep the mixed vial cold.

Research amounts

Supplier descriptions for research use list 250 to 500 mcg per day, injected subcutaneously or intramuscularly, often split into one or two doses, with cycles of about two to six weeks. At 250 mcg per day a 5 mg vial lasts 20 days, and at 500 mcg per day it lasts 10 days. No approved human dose exists.

How to Stack BPC 157

The classic pairing is with TB 500 5 mg, because TB 500 is described as systemic while BPC 157 is usually described as acting where it is injected. Copper peptide GHK-CU 50 mg is the third member of the same repair family and is researched mainly for collagen.

A peptide line is normally added to a cycle rather than replacing it. The anabolic base stays the same, for example Testaplex Testosterone, and AxoTropin HGH is the compound most often named alongside repair peptides because growth hormone also supports connective tissue.

Recovery and Post-Cycle Support With BPC 157

BPC 157 does not suppress the androgen axis, so it needs no post-cycle therapy of its own. Recovery support belongs to the steroid side of the plan: Arimiplex 1 mg or Exeplex 25 mg while on cycle for estrogen, then Clomiplex 50 mg or Tamoxiplex 20 mg afterwards.

Keep expectations sized to the data. Most reports of benefit come from animal models, and the honest position is that human evidence is limited to one small retrospective series and one Phase I trial whose results were never published.

BPC 157 Side Effects and Precautions

What the sources say

Published work describes a favourable safety profile with few serious adverse events. Supplier descriptions mention temporary irritation at the injection site and occasional dizziness. There is no known hormonal activity, because the peptide does not bind androgen receptors.

Regulatory and legal status

BPC 157 is not approved by the FDA or any other regulator, and a 2025 review states plainly that this follows from insufficient clinical research. In some countries, including Australia and New Zealand, it sits in the prescription category while being practically unavailable on prescription.

General precautions

This material is for adult men and is not medical advice. Angiogenesis is central to the mechanism, so anyone with a history of cancer should avoid it. Keep vials away from children and use a fresh needle each time.

Storing and Handling BPC 157

Keep the lyophilized powder in a dry place away from light: either controlled room temperature of 15 to 25 C or the refrigerator at 2 to 8 C, and never freeze the powder. After mixing, store at 2 to 8 C and use within 30 days, avoid repeated freeze-thaw cycles and discard a cloudy solution.
