BPC 157 - Kalpa Pharmaceuticals

Buy BPC 157 2 mg by Kalpa Pharmaceuticals at XSteroids. This is a single 2 mg vial of lyophilised BPC 157, a synthetic pentadecapeptide copied from a fragment of a protein found in human gastric juice. The page explains what the powder is, which pathways the animal literature attributes to it, how honest the human evidence really is, how a 2 mg vial is mixed and read on a U-100 barrel, and what the legal and anti-doping position is.

The status statement is short: this vial is a research product intended for laboratory work, and there is no licensed medicine form of BPC 157. Human data are far thinner than the animal literature, so nothing below is a human dose recommendation or medical advice.

What a BPC 157 2 mg Vial Is and What You Are Buying

BPC 157 is a chain of fifteen amino acids written GEPPPGKPADDAGLV in one-letter code, with the formula C62H98N16O22 and a molecular mass of about 1419.556 g/mol. It carries no international nonproprietary name, because it never reached licensed-medicine status. Older names in the literature include body protection compound 157, bepecin, PL 14736 and gastric pentadecapeptide.

One glass vial per pack holds white lyophilised powder at the 2 mg strength, and bacteriostatic water is sold separately. Kalpa documents the mass on the vial; there is no filler list and no published independent potency test for this batch. Everything quoted on this page is label arithmetic or the published record, never a guess about what is in the glass.

How the BPC 157 Pentadecapeptide Works

The mechanism is best described as multi-pathway rather than single-receptor. In cell and animal models BPC 157 raises the expression of growth factor receptors, including the growth hormone receptor, and interacts with several signalling routes tied to cell growth and blood vessel formation. In the same models it lowers pro-inflammatory cytokines. That breadth is why studies report it across many tissues instead of one target organ.

The measured kinetics come from animals. Half-life of the intact peptide after intravenous or intramuscular dosing is between about 7.9 and 30 minutes in rats, kinetics are linear, and clearance runs through urine and bile. Absolute bioavailability after intramuscular injection was about 14 to 19 percent in rats and 45 to 51 percent in dogs, with metabolism into small peptide fragments and single amino acids. The peptide is unusually stable for its class: it survives intact in human gastric juice for more than 24 hours and is detectable in urine for roughly four days.

What to Expect from BPC 157 Research in 2 mg Vials

A systematic review covering 1993 to 2024 screened 544 publications and included 36 studies. Thirty-five of those were preclinical and only one was clinical. The preclinical column reports faster healing of tissue and organ damage, cytoprotective and neuroprotective changes, and anti-inflammatory shifts, all in animals or cell culture. One human study is not a body of human evidence.

The regulatory position is consistent with that gap: no medicines licence has been issued for BPC 157, and a 2025 review attributes that to the shortage of clinical trials. Marketing copy about rapid healing in people is therefore ahead of the evidence. In sport the substance is prohibited: WADA added BPC-157 to the Prohibited List in 2022 under class S0, its catch-all category, and the 2026 list still names it there, prohibited at all times.

Mixing the 2 mg BPC 157 Vial and Reading a U-100 Barrel

Set the concentration first, because the barrel only shows volume. Work out the concentration by dividing the vial's mass by the volume of water you add. The 2 mg vial with 1 ml of water gives 2 mg per ml, so 0.1 ml carries 200 mcg. The same vial with 2 ml gives 1 mg per ml, so 0.1 ml carries 100 mcg. With 4 ml it gives 0.5 mg per ml and 50 mcg per 0.1 ml.

On a U-100 insulin syringe one unit is 0.01 ml, so 10 units on the scale is 0.1 ml every time, whatever the concentration. Note the concentration and the mixing date on the vial label before it goes into the cold, because that arithmetic alone keeps later draws consistent. A 2 mg vial is a small quantity, which suits a single mixing session better than a large one.

Pairing BPC 157 With TB 500 and GHK-CU

BPC 157 is almost always discussed next to a second repair peptide, and the usual partner is the thymosin beta-4 fragment. TB 500 5 mg is studied as a systemic actin-binding agent, while BPC 157 is studied for local tissue and gut effects, so the two cover different angles on paper. Neither is a licensed medicine.

The copper tripeptide GHK-CU 50 mg is the third member of the repair group on this shelf, and it is studied mainly for skin and connective tissue. Water for all three comes from the same supply card, bacteriostatic water, since every one of them ships dry.

Recovery Notes Around a Repair Peptide Block

A repair peptide acts on tissue repair pathways, not on the testosterone axis, so it does not create the shutdown that requires a post-cycle protocol. There is nothing to restart afterwards. The relevant monitoring is local: injection site condition, any unexpected swelling, and whether a strain or injury is being allowed to heal.

Where a repair vial is used alongside an anabolic cycle, the post-cycle plan belongs to the anabolic compound. Kalpa Pharmaceuticals keeps that shelf separate, from Clomixyl 50 mg to the aromatase inhibitors, and a peptide block does not change what sits on it. Because no medicines licence exists for BPC 157, there is no label instruction on duration, stopping rules or monitoring, and the honest position is that a study block is defined by the researcher, not by a guideline.

BPC 157 Side Effects and Legal Status

There is no established human safety profile, because the clinical dataset is almost empty. The animal literature does not report organ toxicity at the studied amounts, but absence of data in animals is not a safety finding in people. Anything sold as a research peptide is outside pharmaceutical quality control, so purity and exact mass rest on the supplier.

Legally, the substance is a research material rather than a medicine and is not a dietary ingredient, so its status depends on local rules for such products. In anti-doping terms it is unambiguous: class S0 of the WADA list, named explicitly, prohibited in and out of competition without any exemption window.

Handling and Storing the BPC 157 Vial

Store the sealed vial in the refrigerator between 2 and 8 C, shielded from light. The lyophilised powder can also be held at a controlled room temperature of 15 to 25 C for shorter periods, and it should never be frozen in powder form, because ice crystals damage the peptide. In the dry state the vial is stable for a long time.

After mixing, the solution belongs in the fridge between 2 and 8 C and should be drawn on within 28 to 30 days, the window peptide practice gives a reconstituted vial. Do not refreeze a mixed solution, avoid repeated freeze and thaw cycles, and discard the vial if the liquid turns cloudy or contains particles. Keep it well out of reach of children.

Why Buy BPC 157 from XSteroids?

The 2 mg vial is listed inside the Kalpa Pharmaceuticals brand catalog at XSteroids alongside the partner peptides and the diluent it needs, so the whole bench can be covered in one order. The checkout is encrypted; US orders normally arrive in 3 to 6 days while international shipping runs 12 to 26 days. Peptide vials that usually share a mixing session with it are linked below.
