Frequently Asked Questions

PeptideDosing.ca is an information and education website about peptides, research, reconstitution concepts, and measurement calculations. We do not directly sell products. The content is for general information only and is not medical advice, diagnosis, treatment, or a personalized dosing recommendation.

No. Articles, protocol references, calculator results, videos, and external links on PeptideDosing.ca are provided for general information and education only. They are not medical advice and are not a substitute for advice, diagnosis, or treatment from a qualified healthcare professional. A calculator can show measurement arithmetic; it cannot determine whether a substance or dose is appropriate for you. Consult a qualified healthcare professional about personal health decisions.

No. PeptideDosing.ca does not directly sell peptides or other products. We provide information and educational resources. Any supplier or product links lead to third-party businesses; any purchase is made with that seller, not with PeptideDosing.ca. A link is not medical advice or a recommendation to purchase or use a product.

The library distinguishes individual compounds, blends containing multiple components in one vial, and stacks containing separate vials. Capsules and supplies have their own filters. A format label describes the listing; it does not establish that a combination is appropriate for personal use.

Use the contact page to suggest a topic or report a missing reference. Include the product name and labelled strength. Publication is not guaranteed, and the form does not provide personalized dosing advice.

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 calculator does not select a diluent or tell you how much to add. Its input is the final mixed volume, which is distinct from an amount of diluent added. Use independently verified product-specific information. The reverse calculation displays a hypothetical final volume, not a preparation instruction.

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.

The calculator supports a U-100 volume scale: 100 scale units correspond to 1 mL. Barrel capacity and marking spacing are separate properties. A 0.5 mL U-100 barrel is not a U-50 scale, and the smallest printed interval is not necessarily one unit. Confirm the actual device markings and enter their spacing separately. If the spacing is not verified, the calculator cannot check measurement feasibility. See the measurement guide.

Use the measurement calculator in three steps:

1. Vial details. Enter the amount in the vial and the final mixed volume. You can search for a product to fill its labelled amount.
2. Amount to calculate. Enter an independently verified amount and choose mg or mcg.
3. Your device. Select a U-100 syringe or Amino Labs V1. Confirm the device details, then select Calculate.

Read your result. The result shows the volume in mL and equivalent device units. Check any warning above the illustration. Open Calculation details to see the arithmetic.

The product picker supports selected mass-labelled vials. IU-labelled products, capsules, supplies and separate-vial stacks are not supported as single-vial mass selections. The calculator does not determine a suitable dose or storage life.

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.

Once reconstituted with bacteriostatic water, peptides should be refrigerated (2–8°C / 36–46°F) and typically used within 25–30 days, depending on the peptide. Never freeze a reconstituted peptide — the ice crystals can degrade the peptide chain. Keep the vial upright and avoid shaking.

Most reconstituted peptides remain stable for 25–30 days when stored properly in the refrigerator with bacteriostatic water. Some more stable peptides may last longer. If you used sterile water (without benzyl alcohol) instead of BAC water, use the solution within 24–48 hours, as there is no preservative to prevent bacterial growth.

Start with the exact product name, format and strength. Use On this page to navigate the available sections. Article content varies; do not assume that every reference has the same sections, diagrams or supporting sources. The library marks supplier-only entries separately from published references.

The interactive device preview is in the calculator; diagrams are not provided on every protocol page. The preview illustrates the entered calculation only when the relevant device configuration and markings support it. Otherwise it remains at zero and displays an explanation. Match any illustration to the markings on the actual device.

PeptideDosing.ca is not a peer-reviewed journal. Available citations and evidence vary by article. Follow original sources where provided and assess their scope and limitations; do not assume every claim has been independently verified or that a reference is suitable for personal use.

The current public library does not require a reader account. Some references are unavailable, and supplier-only listings open a third-party website. An unavailable reference is not unlocked by creating an account.

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.
