BAC Water & Peptide Reconstitution Guides

BPC-157 is a synthetic peptide derived from a protein found in gastric juice, studied in research settings for tissue repair and recovery.

TB-500 is a synthetic fragment of the protein Thymosin Beta-4, studied in research for tissue repair and flexibility.

Ipamorelin is a lab-made peptide. It is a growth hormone secretagogue, which means it is studied for gently nudging the body's own growth-hormone signals.

CJC-1295 without DAC, also called Mod GRF 1-29, is a lab-made peptide in the growth-hormone group. It has a short half-life, which means it does not last long in the body once it is used.

CJC-1295 with DAC is a lab-made peptide in the growth-hormone group. The 'DAC' part is added so it lasts longer in the body (a longer half-life) than the no-DAC version.

Sermorelin is a lab-made peptide in the growth-hormone group. It is one of the shorter pieces studied in this class.

Hexarelin is a growth hormone releasing peptide known for its potency in research models.

Semaglutide is a lab-made peptide. It is one of the most studied peptides for how the body handles food and weight. It works on a body signal called GLP-1 (a GLP-1 receptor agonist).

Tirzepatide is a lab-made peptide studied for how the body handles food and weight. It works on two body signals at once, called GIP and GLP-1 (a dual receptor agonist), instead of just one.

Retatrutide is an emerging triple receptor agonist peptide studied in metabolic research.

Cagrilintide is a lab-made peptide studied for how the body handles food and weight. It is an amylin analog (a lab-made copy of a natural body signal called amylin) and is often studied next to GLP-1 peptides.

MOTS-c is a lab-made copy of a peptide that comes from the mitochondria, the tiny power plants inside cells. It is studied in metabolic and longevity research.

Epithalon is a small lab-made peptide (it is made of four building blocks, so it is called a tetrapeptide). It is studied in longevity and cellular research.

GHK-Cu is a small lab-made peptide (made of three building blocks, so it is called a tripeptide) that holds onto copper. It is studied in skin, hair, and tissue research.

Melanotan II is a lab-made copy of a natural hormone that affects skin color (a melanocyte-stimulating hormone). It is studied in pigmentation research.

SS-31, also known as Elamipretide, is a lab-made peptide that targets the mitochondria (the tiny power plants inside cells). It is studied in cellular energy research.

Selank is a lab-made peptide based on a natural one that helps steer the immune system. It is studied in cognitive research.

Semax is a synthetic peptide studied in cognitive and neurological research.

AOD-9604 is a lab-made piece of the growth-hormone molecule (a fragment, not the whole thing). It is studied in metabolic research.

Kisspeptin-10 is a peptide studied in reproductive and hormonal signaling research.

PT-141, also known as Bremelanotide, is a lab-made peptide that works on a body signal system called melanocortin. It is studied in reproductive research.

HCG is a hormone studied in reproductive research and typically supplied as a lyophilized research powder.

The Glow Blend is a combination product containing GHK-Cu and BPC-157 in a single vial, studied in skin and recovery research.

This page covers reconstitution for any peptide not listed individually, using the same deterministic math and standard method.

Bac water contains a benzyl alcohol preservative for multi-dose use. Sterile water has none and is single-use. Use bac water for peptide reconstitution.

Saline is 0.9% sodium chloride with no preservative. Bac water adds benzyl alcohol for multi-dose use. Bac water is the standard choice for reconstitution.

0.9% sodium chloride is saline: salt water with no preservative. Bac water is preserved sterile water. Use bac water for multi-dose peptide reconstitution.

Distilled, deionized, and tap water are not sterile and not for injection. Only use bacteriostatic or sterile water to reconstitute peptides.

Benzyl alcohol is not an alternative to bac water. It is the 0.9% preservative inside bac water that makes it bacteriostatic and multi-dose safe.

Bac water dissolves most peptides. Dilute acetic acid is only used for specific peptides that will not fully dissolve in water. Bac water is the default.

Reconstitution solution is usually bacteriostatic water under another name. Check the label for 0.9% benzyl alcohol to confirm it is preserved for multi-dose use.

Shaking the vial : swirl gently. Shaking can denature peptides. Aiming the water at the powder : angle it against the wall of the vial. Skipping the label : alw

Bacteriostatic water is sterile water mixed with 0.9% benzyl alcohol. The alcohol prevents bacterial growth, which is why the same vial can be used across multi

Peptides are shipped as a freeze dried powder. To use them, you add BAC water to the vial, which dissolves the powder into a stable solution you can draw from.

A peptide vial label shows: the peptide name, the strength (usually in mg), a lot number, and sometimes an expiration for the powder. The strength is the total

Insulin syringes are marked in units on the U 100 scale: 100 units = 1 mL. A 1 mL insulin syringe has 100 markings; a 0.5 mL has 50; a 0.3 mL has 30 (often with

What You Need Tirzepatide vial (common strengths: 5 mg, 10 mg, 15 mg) Bacteriostatic water (BAC water) Insulin syringe (0.5 mL or 1 mL) Alcohol prep pads Step b

What You Need Semaglutide vial (common strengths: 3 mg, 5 mg) Bacteriostatic water (BAC water) Insulin syringe (0.5 mL or 1 mL) Alcohol prep pads Step by Step I

How to Use This Chart Find your peptide below. The chart shows common vial strengths, a suggested BAC water amount, the resulting concentration, and the syringe

Short Answer Adding too much BAC water does not ruin the peptide. It simply dilutes the concentration, meaning you will need to draw a larger volume per dose. W

What You Need BPC 157 vial (typically 5 mg) Bacteriostatic water (BAC water), 30 mL vial Insulin syringe (1 mL / 100 units recommended) Alcohol prep pads Step b

Why bacteriostatic water is the standard solution for reconstituting peptides, how much to add, and what to use instead of sterile water or saline.
