Peptide Dosage Chart 2026: Every Compound in One Reference Table

How to Use This Dosage Chart

This reference table compiles the standard dosing ranges for 30 of the most commonly used research peptides. Doses listed here represent the ranges most frequently referenced in published research, clinical trials, and established practitioner protocols as of 2026.

Important: These are general reference ranges, not prescriptions. Individual dosing should be determined in consultation with a qualified healthcare provider. Factors including body weight, health status, goals, and response to the compound all influence optimal dosing. For body-weight-based dosing calculations, see our dosing by body weight guide.

Key Dosing Principles

Before calculating your dose, understand the principles that guide peptide dosing across every compound category:

Start Low, Titrate Slowly. This principle applies universally. Begin at the lower end of the dose range listed above and increase gradually over days or weeks. For GLP-1 agonists, formal titration schedules exist precisely because starting at full dose causes unacceptable nausea in most people. For GH secretagogues, starting low lets you gauge your sensitivity to GH-related side effects (water retention, numbness) before committing to higher doses.

More Is Not Always Better. Peptide dose-response curves are rarely linear. With GH secretagogues, for example, there is a ceiling beyond which additional peptide does not produce additional GH release — the pituitary has finite GH stores per pulse. Exceeding the optimal dose simply increases side effects without proportional benefit. This ceiling effect is well-documented for Ipamorelin at approximately 300 mcg per dose and for Hexarelin at 200 mcg.

Consistency Over Intensity. For peptides with short half-lives (most GH secretagogues have half-lives of 30 minutes to 2 hours), consistent daily dosing produces better cumulative results than sporadic high doses. A 200 mcg dose of Ipamorelin taken consistently every night before bed will outperform 600 mcg taken three times per week, because GH is released in pulsatile fashion and each pulse has a saturation point.

Compound-Specific Considerations Matter. The table above lists general ranges, but context matters. A 250 mcg dose of BPC-157 for a minor tendon issue may be appropriate, while the same injury in a 250-pound individual under heavy training stress might warrant 500 mcg. Similarly, GLP-1 agonist titration speed may need to be adjusted based on gastrointestinal tolerance, metabolic response, and clinical goals.

Track and Adjust. Keep a simple log of dose, timing, injection site, and any effects or side effects. After 2 to 4 weeks, review your log and adjust. If side effects are minimal and results are suboptimal, a modest dose increase is reasonable. If side effects are present but results are good, you may be at your sweet spot — or slightly above it. Data drives good decision-making; guesswork does not.

Common Dosing Mistakes

Confusing mg and mcg. This is the most dangerous dosing error. One milligram (mg) equals 1,000 micrograms (mcg). A dose of 300 mcg is 0.3 mg — not 3 mg. Double-check your units every time. A 10x dosing error can produce serious adverse effects, particularly with potent compounds like IGF-1 LR3 or PT-141.

Using the wrong reconstitution volume. The amount of bacteriostatic water you add to the vial determines the concentration. Adding 1 mL to a 5 mg vial gives 5 mg/mL (5,000 mcg/mL). Adding 2 mL gives 2.5 mg/mL (2,500 mcg/mL). Using the wrong water volume means every subsequent dose calculation is off. Write the reconstitution volume on the vial label. Our peptide calculator eliminates the math entirely.

Skipping the titration schedule. GLP-1 agonists like semaglutide require 16 to 20 weeks of gradual titration for a reason. Jumping to a maintenance dose causes severe nausea, vomiting, and diarrhea in most people. Even for peptides without formal titration schedules, the principle of starting low applies.

Dosing based on someone else's protocol. Online forums are full of dosing recommendations, but individual response varies enormously. Body weight, body composition, receptor sensitivity, metabolic status, and health conditions all influence the optimal dose. Use published ranges as a starting framework and adjust based on your own response and, ideally, bloodwork results.

How to Calculate Your Dose

Most peptides arrive in milligram quantities (e.g., a 5 mg vial) but are dosed in micrograms. The calculation process:

1. Reconstitute: Add a known volume of bacteriostatic water (e.g., 2 mL to a 5 mg vial).
2. Calculate concentration: 5 mg / 2 mL = 2.5 mg/mL = 2,500 mcg/mL.
3. Determine volume per dose: If your dose is 250 mcg, you need 250 / 2,500 = 0.1 mL = 10 units on an insulin syringe.

Our Peptide Dosage Calculator performs this math instantly. Enter your vial size, water volume, and desired dose to get the exact number of units to draw.

Body Weight Adjustments

Some peptides use weight-based dosing (mcg/kg), while others use flat doses regardless of body weight. General guidelines:

• Flat dosing (most common): CJC-1295, Ipamorelin, BPC-157, TB-500, Epitalon, DSIP, GHK-Cu, and most research peptides use flat doses within a range.
• Weight-based dosing: Semaglutide and tirzepatide use titration protocols rather than weight-based math, but larger individuals may require higher maintenance doses. Some practitioners dose BPC-157 at 5-10 mcg/kg.
• Body composition matters: For GLP-1 agonists, higher starting BMI may require a slower titration schedule due to increased GI sensitivity.

For a detailed breakdown, see our body weight dosing guide.

Timing Considerations

When you take a peptide can be as important as how much you take:

• GH secretagogues (CJC-1295, Ipamorelin): Best taken on an empty stomach, ideally before bed or first thing in the morning. Fats and carbohydrates blunt GH release. Wait at least 30 minutes before eating after injection.
• Semaglutide / Tirzepatide: Once-weekly injections can be given at any time of day, with or without food. Consistency matters more than timing.
• BPC-157 / TB-500: Can be taken at any time. For healing applications, some practitioners split BPC-157 into two daily doses (morning and evening) for more consistent tissue exposure.
• DSIP: Take 30 to 60 minutes before bedtime.
• Semax / Selank: Morning dosing for cognitive enhancement; Selank can also be taken in the evening for anxiolytic effects.

Reconstitution Quick Reference

Every injectable peptide on the chart above must be reconstituted before use. Here is the standard process in brief:

1. Gather supplies: Lyophilized peptide vial, bacteriostatic water (preferred) or sterile water, alcohol swabs, and an insulin syringe (29-31 gauge).
2. Swab the vial tops with alcohol pads. Let them air dry for 10 seconds.
3. Draw your chosen water volume into the syringe. Common volumes: 1 mL or 2 mL. The volume determines your concentration — see the calculation section above.
4. Inject the water slowly down the inside wall of the peptide vial. Do not squirt directly onto the powder — this can damage the peptide through excessive shear force.
5. Gently swirl (never shake) until the powder dissolves completely. Most peptides dissolve within 30 seconds to 2 minutes. If it does not dissolve, let it sit refrigerated for 15 minutes and try again.
6. Label the vial with the compound name, reconstitution date, concentration, and the volume of water used.

For a complete walkthrough with troubleshooting, see our full reconstitution guide. For injection technique and site selection, see the injection sites body map.

Storage After Reconstitution

Reconstituted peptides must be refrigerated at 36-46 degrees Fahrenheit (2-8 degrees Celsius). With bacteriostatic water, most peptides remain stable for 3 to 4 weeks. With sterile water, use within 24 to 48 hours. Never freeze reconstituted peptides — ice crystal formation damages the molecular structure. Keep vials upright, away from light, and on a middle shelf rather than in the door where temperature fluctuates.
