Peptide Dosage Chart

This peptide dosage chart compiles commonly referenced research dosage ranges for popular peptides. Use it to understand the terms in a source you already have and to check concentration math. It does not choose a personal dose, schedule, product, or route. All dosages are for research reference only — consult a healthcare provider before using any peptide.

SubQ = subcutaneous; IM = intramuscular; IV = intravenous. Source-type labels: Supp. docs = supplier documentation; Clinical = published clinical study; Animal / Preclinical = non-human data only. Route labels describe cited source context, not administration instructions.

FDA-Approved GLP-1 Medications

GLP-1 metabolic medicines use labelled titration schedules. The entries below point to official information; they are not a personal prescription. Never begin at a target dose.

Medicine	Start → target in label or trial	Source
Semaglutide	0.25 → 2.4 mg weekly	FDA label
Tirzepatide	2.5 → 15 mg weekly	FDA label
Cagrilintide	0.3 → 4.5 mg weekly in trials	Clinical trial registry; not FDA-approved

How Peptide Dosage Is Calculated

The arithmetic is simple once the inputs are confirmed. First translate a documented mass into a concentration; then translate a separately confirmed amount into a liquid draw volume. A syringe scale is the last conversion step, not a substitute for knowing concentration.

Step 1 · Draw volume

draw volume (mL) = dose (mg) ÷ concentration (mg/mL)

This equation does not establish the dose; it only converts a confirmed amount. Doses are often stated in mcg: 1 mg = 1,000 mcg. Convert before dividing.

Step 2 · U-100 only

syringe units = draw volume (mL) × 100

Use this only after confirming that the syringe packaging identifies it as U-100. Other calibrations use a different scale.

Concentration input

concentration (mg/mL) = vial amount (mg) ÷ confirmed final liquid volume (mL)

“Confirmed final liquid volume” is a documented input. This page does not select the liquid, volume, or preparation method.

01 · Verify

Match the source

Confirm the product, formulation, units, document version, vial amount, and final liquid volume. Make sure the vial label and source document match before entering a number.

02 · Convert

Keep units explicit

Convert mg to mcg only when helpful: 1 mg equals 1,000 mcg. Do not use syringe markings as a mass unit. Write the unit beside every amount so the calculation stays readable.

03 · Cross-check

Read the full context

Keep route, product form, stated conditions, and safety information with the original source rather than copying a number alone.

Example: Convert Your Dose to Units

Concentration = mg ÷ mL

Draw volume = stated amount ÷ concentration

U-100 units = draw volume in mL × 100

Example calculation

5 mg in 2 mL = 2.5 mg/mL. A stated 0.5 mg amount = 0.2 mL = 20 U-100 units.

Example calculation

10 mg in 2 mL = 5 mg/mL. A stated 0.25 mg amount = 0.05 mL = 5 U-100 units.

Example calculation

5 mg in 1 mL = 5 mg/mL. A stated 0.5 mg amount = 0.1 mL = 10 U-100 units.

Use the numbers from your vial to calculate the matching mL and U-100 units.

Frequently Asked Questions

Is this peptide dosage chart a prescription or medical advice?

No. This chart compiles commonly referenced research dose ranges and is a research reference only — not a prescription. Dose decisions belong to you and a clinician.

How do I read the dose ranges in this chart?

Ranges reflect commonly cited research contexts, not universal recommendations. Source-type labels (Supp. docs / Clinical / Animal) show where each figure comes from.

How many units is 500 mcg on a U-100 syringe?

It depends on concentration. At 2.5 mg/mL, 500 mcg equals 0.2 mL, or 20 units on a U-100 syringe. Always confirm your own concentration first.

Do GLP-1 medicines like semaglutide start at the target dose?

No. They are titrated from a low starting dose upward (for example, 0.25 mg weekly for semaglutide). Never begin at a target dose — see the FDA label section above.

Why does the chart show different routes such as SubQ, IM, or topical?

The same peptide can appear with different routes across published research. Route labels describe cited source context only and are not administration instructions.

Where do these ranges come from?

They come from publicly available research literature, product documentation, and FDA labels where applicable. See the Sources section below for the source types used on this page.
