PeptideDosages.com is an educational resource providing comprehensive dosage protocols, reconstitution guides, and research-backed information for peptides. Our guides are designed for researchers and are sourced from published clinical literature, FDA labeling, and peer-reviewed studies — not forums or marketing copy.

Single Peptides are individual peptide compounds (e.g., BPC-157 5mg, Semaglutide 3mg). Blends are pre-mixed combinations of two or more peptides in a single vial (e.g., CJC-1295/Ipamorelin 10mg Blend). Stacks are protocols that involve using multiple separate vials together in a coordinated dosing schedule.

Reconstitution is the process of adding a diluent (typically bacteriostatic water) to a lyophilized (freeze-dried) peptide powder to create an injectable solution. The amount of diluent you add determines the concentration, which in turn determines how much liquid you draw per dose.
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits bacterial growth, which allows the reconstituted peptide to remain viable for multiple uses over days or weeks when stored properly. It is the standard diluent used for reconstituting lyophilized peptides.
The amount varies by protocol and vial size. Each of our dosage protocol pages specifies the recommended BAC water volume, typically chosen to create a round-number concentration that makes dose measurement straightforward. Common volumes are 1 mL, 2 mL, or 3 mL per vial. You can also use our Dosage Calculator to compute exact injection volumes for any BAC water amount.
mg (milligrams) is a unit of weight — how much peptide powder is in the vial. IU (International Units) is a unit of biological potency used for specific peptides like HGH and HCG, where the relationship between weight and biological activity has been standardized. For example, for somatropin (HGH), the standard conversion is approximately 3 IU per 1 mg. Not all peptides use IU — most are dosed in mg or mcg (micrograms).
1 mg (milligram) = 1,000 mcg (micrograms). Many peptides are dosed in micrograms because effective doses are very small. For example, a 250 mcg dose is the same as 0.25 mg. Always pay attention to whether a protocol specifies mg or mcg — confusing the two results in a 1,000x dosing error.
Most peptide protocols use U-100 insulin syringes (typically 0.5 mL or 1 mL capacity). On a U-100 syringe, 100 “units” equals 1 mL, so each tick mark represents 0.01 mL. Some protocols may call for U-50 or U-20 syringes for more precise small-volume measurements. Our protocol pages specify which syringe type to use and how many units to draw.
Our Dosage Calculator lets you input the total peptide amount in your vial, the amount of BAC water you added, and your target dose per injection. It then calculates the exact volume to draw in your syringe and how many total doses you’ll get from the vial. It works for any peptide and any vial size.
Unreconstituted (lyophilized) peptides should be stored in a cool, dry place away from direct light. Refrigeration (2–8°C / 36–46°F) is ideal for long-term storage. Some peptides can also be frozen for extended storage. Always check the specific peptide’s storage recommendations.
After reconstitution, follow the product-specific storage directions and use-by instructions. Bacteriostatic water does not establish a universal shelf life or guarantee that a punctured vial remains sterile.
Storage life depends on the exact peptide, formulation, container, and tested conditions. Sterile water has no antimicrobial preservative, so do not assume a reconstituted vial can be accessed repeatedly or kept for a generic period. Follow the product label and applicable sterile-preparation guidance.
Each protocol page follows a consistent format. You’ll find a Protocol Overview (what the peptide is and what it’s researched for), a Dosing Schedule (how much to inject and how often), Reconstitution Instructions (how to mix the vial), and a Supplies List (what you’ll need). A syringe visualization shows the exact fill line for each dose.
The syringe visualizations on each protocol page show the exact fill line for your dose after reconstitution with the recommended amount of BAC water. The diagram indicates the syringe type (U-100, U-50, or U-20), the number of units to draw, and the equivalent volume in mL.
Our protocols are not peer-reviewed in the academic journal sense, but all dosage information, mechanisms of action, and safety notes are sourced from peer-reviewed literature, FDA labeling, clinical trial data, and established endocrine/pharmacology references. Every protocol page includes inline citations with links to original sources.
A small number of protocols are gated behind a free account to help us manage content access and understand which protocols are most in demand. Creating an account is free and only requires an email address.
Legality varies by country, jurisdiction, and specific peptide. In the United States, many peptides are sold as “research chemicals” not intended for human consumption. Some peptides (like semaglutide, HGH, and HCG) are FDA-approved prescription drugs when used in clinical contexts. Others have specific legal restrictions — for example, federal law (21 U.S.C. § 333(e)) restricts HGH distribution for non-medical human use. Always check your local regulations.
Many peptides are prohibited by the World Anti-Doping Agency (WADA), including growth hormone, GH secretagogues (e.g., CJC-1295, Ipamorelin, MK-677), GH fragments, and others. If you compete in any tested sport, check the current WADA Prohibited List before considering any peptide.
Side effects vary widely by peptide. Common ones across many peptides include injection site reactions (redness, swelling), headaches, nausea, and fatigue. Growth hormone-related peptides may cause water retention, joint pain, and changes in glucose tolerance. Each of our protocol pages includes a safety section with peptide-specific side effects sourced from clinical literature.
Some peptides are commonly used together (which is what our Stacks and Blends sections cover), but combining compounds always adds complexity and potential interaction risks. Our stack protocols note which combinations have research support and which are more experimental. Consult a healthcare professional before combining any compounds.
