Every step explained, every number calculated. C BioChonch Research Editor · BodyHackGuide What Reconstitution Means Jump to section For research and educational purposes only. Not medical advice. BPC-157 is not FDA approved. Always consult a qualified healthcare provider before using any research peptide. You ordered your first vial of BPC-157. It arrived as a tiny puck of white powder sealed under vacuum. Now what? Reconstitution is the step that trips up most beginners. You need to turn that freeze-dried powder into a liquid solution at a precise concentration so you can measure accurate doses with an insulin syringe. Get it wrong and you either destroy the peptide, contaminate the vial, or end up injecting wildly inaccurate amounts. This guide walks through the entire process from start to finish. Every step has a reason. The calculator does the math for you. And the common mistakes section at the end will save you from the errors that waste vials and money. ## What Reconstitution Means Reconstitution is the process of adding a specific volume of bacteriostatic water to a vial of lyophilized (freeze-dried) peptide powder to create an injectable solution. The word literally means "to bring back together" — you are restoring the peptide to a liquid state so it can be measured and administered. Peptides like BPC-157 ship as freeze-dried powder because it is far more stable in that form. A lyophilized vial stored properly can last two years or longer without significant degradation. Once you add water and create a solution, the clock starts ticking — the peptide begins slowly breaking down and bacterial contamination becomes possible with every needle puncture of the stopper. The key concept to understand is that the amount of water you add determines the concentration of your solution , which directly determines how many units on your syringe equal a specific dose. Add 2mL of water to a 5mg vial and you get 2.5 mg/mL. Add 1mL and you get 5 mg/mL. The peptide amount stays the same — you are only changing how concentrated the solution is. BPC-157 (Body Protection Compound-157) is a 15-amino acid pentadecapeptide derived from a protective protein found in human gastric juice. It is most commonly available as lyophilized powder in 5mg and 10mg vials . Both vial sizes are reconstituted the same way — the only difference is the resulting concentration and how long the vial lasts. ## What You Need Gather everything before you start. Working with an incomplete setup leads to contamination and wasted peptide. ### BPC-157 Vial 5mg or 10mg lyophilized powder. Should appear as a small white puck or powder at the bottom of the vial. ### Bacteriostatic Water NOT sterile water. NOT saline. BAC water contains 0.9% benzyl alcohol as a preservative for multi-dose use. ### Insulin Syringes U-100 insulin syringes, 1cc (1mL), 29-31 gauge needle. These are the standard for subcutaneous peptide injection. ### Alcohol Swabs 70% isopropyl alcohol prep pads. Used to sterilize vial stoppers before each needle insertion. Optional: A separate 3cc (3mL) syringe with a larger needle (21-23 gauge) makes it easier to draw bacteriostatic water from the BAC water vial. The larger needle draws water much faster than an insulin syringe. ### Why Bacteriostatic Water Specifically? Bacteriostatic water contains 0.9% benzyl alcohol , which acts as a preservative that inhibits bacterial growth. This is critical because you will be puncturing the vial stopper multiple times over days or weeks to draw individual doses. Each puncture is an opportunity for contamination. The benzyl alcohol keeps the solution safe for up to 28 days of multi-dose use. Sterile water, by contrast, has zero preservative. The moment you puncture the stopper with a needle, bacteria can enter and begin multiplying with nothing to stop them. It is technically usable for a single draw from a single-use vial but is never appropriate for multi-dose peptide vials. Never use: tap water, distilled water, normal saline (0.9% NaCl), or any water not explicitly labeled as bacteriostatic. Tap water and distilled water are not sterile. Saline can cause peptide aggregation and has no preservative. ## Step-by-Step Reconstitution Guide Follow these seven steps exactly. The entire process takes about five minutes once you have done it a few times. 1 ### Step 1: Clean Your Workspace and Wash Hands Wipe down your workspace with 70% isopropyl alcohol or a clean surface. Wash your hands thoroughly with antibacterial soap for at least 20 seconds and dry them completely with a clean towel. Contamination is the biggest risk during reconstitution. A clean environment and clean hands are your first line of defense. Some people wear nitrile gloves for added protection. 2 ### Step 2: Remove Caps and Swab Vial Stoppers Pop off the colored plastic flip-top caps from both the BPC-157 vial and the bacteriostatic water vial. These caps are not sterile — they are just dust covers. Beneath them you will find a rubber stopper held in place by an aluminum crimp seal. Take a fresh alcohol swab and firmly wipe the exposed rubber stopper on each vial. Let them air-dry for about 10 seconds. Do not blow on them. Alcohol needs a moment of contact time to be effective against surface bacteria. 3 ### Step 3: Draw Bacteriostatic Water Into Your Syringe Insert your syringe needle through the center of the BAC water vial stopper. Invert the vial and slowly draw the desired amount of water. Common volumes are 2mL for a 5mg vial (gives 2,500 mcg/mL) or 1mL for a 5mg vial (gives 5,000 mcg/mL). If using an insulin syringe, this takes patience because the 29-31 gauge needle is thin. A 3cc syringe with a 21-gauge needle draws water in seconds, then you transfer it through the peptide vial stopper. 4 ### Step 4: Inject Water Into the Peptide Vial — Slowly, Down the Side Insert the needle through the BPC-157 vial stopper at a slight angle so the needle tip touches the inside glass wall of the vial. Slowly depress the plunger so the water trickles down the inside wall of the vial . Do not inject the water directly onto the powder cake. This is the most critical step. Blasting water directly onto the lyophilized powder can break peptide bonds and reduce potency. Letting the water gently flow down the side and pool at the bottom preserves the structural integrity of the peptide. Take at least 30 seconds to inject the full volume. 5 ### Step 5: Let the Peptide Dissolve — Never Shake Once the water is in the vial, let it sit. The powder will begin dissolving on its own within a minute or two. You can gently swirl the vial by rolling it between your palms to help the process. Some people gently tip the vial back and forth. Never shake the vial. Shaking introduces air bubbles and creates mechanical stress that can denature (unfold) the peptide chain, destroying its biological activity. If you see foam or bubbles after shaking, you have likely damaged some of the peptide. BPC-157 typically dissolves completely within 2-3 minutes without agitation. 6 ### Step 6: Verify the Solution Is Clear Hold the vial up to a light source and inspect the solution. A properly reconstituted BPC-157 solution should be completely clear and colorless , looking identical to the bacteriostatic water you started with. There should be no visible particles, cloudiness, or discoloration. If you see floating particles, cloudiness, or a yellowish tint, something went wrong. The peptide may have been degraded before reconstitution (poor storage by the supplier), or it was damaged during the mixing process. Do not inject a cloudy solution. 7 ### Step 7: Draw Your Dose With a Fresh Insulin Syringe Take a brand-new, unused insulin syringe . Swab the vial stopper with alcohol again. Insert the needle, invert the vial, and slowly draw your calculated dose. Tap the syringe gently to move any air bubbles to the top, then push the plunger slightly to expel them. Always use a fresh syringe for drawing your dose — never reuse the syringe you used to add the BAC water. That syringe has already been through two vials and is no longer sterile. After drawing your dose, store the reconstituted vial in the refrigerator immediately. ## Reconstitution Calculator Use the calculator below to find your exact concentration and syringe draw volume based on your specific vial size and the amount of water you plan to add. It handles the math so you do not have to. [ ### BPC-157 Reconstitution Calculator Enter your vial size and water volume — get exact syringe units for any dose ](/tools/reconstitution/bpc-157) ### The Math — How Concentration Works The formula is straightforward: Peptide amount (mg) / Water volume (mL) = Concentration (mg/mL) . Once you know the concentration, you can calculate the exact syringe volume for any dose. Worked Example: 5mg vial + 2mL BAC water 5 mg / 2 mL = 2.5 mg/mL = 2,500 mcg/mL For a 250 mcg dose : 250 / 2,500 = 0.1 mL = 10 units on a U-100 syringe For a 500 mcg dose : 500 / 2,500 = 0.2 mL = 20 units on a U-100 syringe U-100 syringe key: A U-100 insulin syringe has 100 units per 1mL. So 10 units = 0.1 mL, 20 units = 0.2 mL, 5 units = 0.05 mL. This is always the same regardless of what solution is in the syringe. ### Common Setups at a Glance Vial Water Concentration 250 mcg 500 mcg 5 mg 1 mL 5,000 mcg/mL 5 units 10 units 5 mg 2 mL 2,500 mcg/mL 10 units 20 units 10 mg 2 mL 5,000 mcg/mL 5 units 10 units 10 mg 3 mL 3,333 mcg/mL 7.5 units 15 units The 5mg vial + 2mL water setup is the most popular choice among beginners because it yields clean, easy-to-measure numbers on a standard insulin syringe. 10 units for 250 mcg leaves no room for math errors. ## Storage After Reconstitution How you store your BPC-157 determines how long it stays active. Temperature, light, and contamination are the three enemies of a reconstituted peptide. ### Lyophilized (Unreconstituted) - \- Store at -20 C (freezer) for maximum shelf life - \- Keep desiccated (dry) and protected from light - \- Stable for 2+ years when properly stored - \- Room temperature storage is acceptable for months but not ideal ### Reconstituted (In Solution) - \- Store at 2-8 C (standard refrigerator) - \- Use within 28 days of reconstitution - \- Never freeze a reconstituted peptide solution - \- Keep away from direct light (store in box or wrap vial) Avoid repeated temperature cycling. Taking the vial out of the fridge, leaving it on the counter for 30 minutes, then putting it back accelerates degradation. Draw your dose quickly and return the vial to the refrigerator immediately after each use. If the reconstituted solution becomes cloudy, develops visible particles, or changes color at any point during the 28-day window, discard the entire vial. Cloudiness indicates either peptide aggregation (degradation) or bacterial contamination. Do not attempt to filter or salvage it. ## 6 Common Mistakes That Waste Your Peptide Every one of these mistakes costs you money, potency, or safety. Most of them are easy to avoid once you know about them. 1 ### Spraying water directly onto the powder cake The force of the water stream can break peptide bonds, reducing the biological activity of the compound. Always aim the needle at the inside wall of the vial and let the water trickle down slowly. The powder will dissolve from the bottom up as water pools beneath it. 2 ### Shaking the vial Shaking creates mechanical stress and air-liquid interfaces that cause peptide denaturation — the protein chain unfolds and loses its three-dimensional structure. This is the same reason insulin labels say "do not shake." If you see foam, you have damaged peptide. Gentle swirling only. 3 ### Using sterile water instead of bacteriostatic water Sterile water has no preservative. The moment you puncture the stopper, bacteria can enter and grow without anything to stop them. By day three or four, a sterile water vial can have significant bacterial load. Bacteriostatic water with 0.9% benzyl alcohol prevents this for up to 28 days. 4 ### Drawing doses with the same syringe used to add water The syringe you used to transfer BAC water has already punctured two vial stoppers. It is no longer sterile. Using it again to draw a dose introduces contamination risk and can transfer trace amounts of rubber or debris. Always use a fresh, sealed insulin syringe for every dose you draw. 5 ### Leaving the reconstituted vial at room temperature Reconstituted BPC-157 degrades significantly faster at room temperature. Peptide bonds hydrolyze, and any trace bacteria multiply rapidly above 8 C. Leaving a vial on your bathroom counter for a morning can cost you noticeable potency. Draw your dose and put the vial back in the fridge within a minute. 6 ### Using too little water (hyper-concentrating) Adding only 0.5 mL to a 5mg vial gives 10,000 mcg/mL — meaning a 250 mcg dose is only 2.5 units on your syringe. At that tiny volume, even a half-unit error means a 20% dosing mistake. Using 2mL of water gives a more forgiving 10-unit draw for the same dose, making accurate measurement much easier. ## BPC-157 Dosing Guide BPC-157 has not been tested in human clinical trials with published dose-ranging data. The dosing information below is derived from animal studies scaled to human-equivalent doses and from widespread community reporting. None of this constitutes medical advice. ### Typical Research Protocol Dose Range 200-500 mcg per injection Frequency 1-2 times daily (subcutaneous) Injection Sites Abdominal subcutaneous fat, rotate sites Cycle Length 4-8 weeks typical, some run longer The most common protocol in the community is 250 mcg injected subcutaneously twice daily — once in the morning and once in the evening — for a total of 500 mcg per day. Some users run higher doses of 500 mcg twice daily (1,000 mcg/day) for acute injuries, while others use a lower maintenance dose of 200 mcg once daily. A common community practice is to inject close to the injury site under the theory that local concentration will be higher. However, this is not strongly supported by the pharmacokinetic data. After subcutaneous injection, BPC-157 distributes systemically through the bloodstream. Research in animal models shows widespread tissue distribution regardless of the injection site ([PMID: 21524250](https://pubmed.ncbi.nlm.nih.gov/21524250)). Injecting near the injury is unlikely to cause harm, but the abdominal area remains the most practical injection site for consistent subcutaneous depth.
