Peptide Dosage Chart: Doses for Every PeRx Peptide

Every peptide PeRx prescribes, in one dosing reference: route, typical dose, and frequency, with a link to the detailed chart for each. Plus the syringe math that turns milligrams into units, and the reason charts from different pharmacies never quite agree.

Key Takeaways

  • Every dose in this chart comes from the detailed PeRx per-peptide dosing pages or the published typical dosing for each product. Your own prescription label overrides all of it.
  • Most PeRx peptides are subcutaneous injections drawn with a U-100 insulin syringe, where 100 units equal 1 mL. Two products are oral capsules, and the sublingual GLP-1s are a liquid held under the tongue.
  • Syringe units mean nothing without concentration. The conversion is units = (mg divided by the vial mg/mL) times 100, so the same milligram dose becomes a different draw at a different strength.
  • PeRx vials arrive ready to use at a fixed, labeled concentration, which is why charts here will not match calculators built for research vendors that sell powder you dissolve yourself.
  • Semaglutide and tirzepatide do not follow a fixed chart at all. Dose escalation is a provider-managed titration reviewed at each renewal.
  • Some peptides run in defined cycles with planned breaks and others run continuously. The frequency column notes the pattern, and the cycling guide covers the reasoning.

Peptide Dosage Chart: Every PeRx Peptide

The tables below cover the full PeRx catalog, grouped by family so you can find a product without scrolling one enormous grid. The dose column shows the typical published or clinic pattern behind each product, taken from the detailed per-peptide dosing pages linked in the last column or from the published typical dosing for products that do not have a dedicated chart yet. None of these rows is a menu. A licensed provider reviews your health history before anything is prescribed, and the instructions on your prescription label are the only chart that applies to you.

Two blends, AOD-9604 and the AOD-9604/MOTS-C combination, are currently out of stock and are left out of the tables until they return. Everything else listed is available through a provider consultation.

Weight Management: GLP-1 Subscriptions

The GLP-1 rows work differently from everything else on this page. Semaglutide and tirzepatide dosing is a titration: your provider starts you at a strength, reviews how you respond, and adjusts the strength of the vial over time while the injection volume stays familiar. There is no fixed chart to pick from, which is deliberate. One clarification worth a sentence: these are compounded preparations made for an individual patient under a prescription, not the branded pens, and they are not interchangeable with any branded product.

The label governs

Every number above is a reference point, not an instruction. Providers adjust doses for body weight, goals, labs, and response, and the compounding pharmacy prints the result on your vial. When this page and your prescription label disagree, the label wins without exception. If the label itself confuses you, call your provider rather than improvising.

How to Read a Peptide Dosage Chart

A dosing chart is a translator. It exists so that a number quoted in a study, on a forum, or on another pharmacy label can be converted into what it means for the vial in your refrigerator. Reading one well takes three habits. First, check the unit. Signaling peptides like BPC-157 and DSIP are dosed in micrograms (mcg), while larger doses like tesamorelin, MOTS-C, and glutathione are quoted in milligrams (mg). One milligram is 1,000 micrograms, so confusing the two is a thousand-fold error, and it is the single most common mistake people make when comparing charts.

Second, check whether the number is a per-dose amount or a weekly total. MOTS-C clinic patterns are usually quoted as 5 to 15 mg per week split across two or three injections, which is a very different instruction from 15 mg in one sitting. Third, check the concentration the chart assumes, because that is what connects milligrams to the marks on a syringe. The next section does that math once so you never have to trust a chart blindly again.

Where a row above shows a range rather than one number, that range reflects the span of published and clinical practice, not a slider for you to set. Your provider picks the point in the range that fits your case. And where a row says per provider guidance, that is not a dodge: those products, mostly blends, have protocols set individually during the intake review rather than a single published reference dose.

Milligrams, Micrograms, and Insulin-Syringe Units

Injectable PeRx peptides are drawn with a U-100 insulin syringe. U-100 means 100 units per milliliter, so one unit is 0.01 mL of liquid. A unit is a volume, not an amount of peptide. How much peptide rides in each unit depends entirely on the concentration of the vial, which is why the same syringe mark can hold 30 mcg of one product and 2 mg of another.

The only formula you need

units = (dose in mg / vial concentration in mg per mL) x 100. Worked example: sermorelin ships at 3 mg/mL, and the prescribed dose is 600 mcg, which is 0.6 mg. So 0.6 / 3 = 0.2 mL, and 0.2 x 100 = 20 units. Glutathione ships at 200 mg/mL, so each unit holds 2 mg and a 100 mg dose is 50 units. Same syringe, wildly different payloads.

This is also why round syringe numbers show up so often in the tables. A pharmacy that controls the concentration can set it so the prescribed dose lands on an easy mark: 20 units for sermorelin, 20 units for thymosin alpha-1, 20 units for KLOW. A mark you can read at a glance is a dose that is hard to get wrong at eleven at night. Drawing, injecting, and rotating sites are their own skill, and how to inject peptides walks through the mechanics from hand washing to sharps disposal if any of this is new.

Why Charts Differ Between Pharmacies

Search any peptide dose and you will find charts that flatly contradict each other. Usually nobody is lying; they are describing different vials. Research vendors sell peptide as a dry powder that the buyer dissolves at home, which means the concentration is whatever the buyer makes it, and every calculator on those sites exists to solve a problem the buyer created. A prescribed PeRx vial arrives fully reconstituted and ready to use at a fixed concentration chosen by the compounding pharmacy and printed on the label. The units math is done before the box ships, so a chart built for mix-your-own products simply does not transfer.

Branded drugs add their own version of the same confusion. Tesamorelin has carried three different labeled doses since 2010, at 2 mg, 1.4 mg, and 1.28 mg, because the manufacturer changed formulations, not because the FDA cut the dose. The tesamorelin dosage chart untangles that story. The general rule: a dose only means something next to its concentration and formulation. When you see a conflicting number online, the first question is never who is right, it is what vial they are describing.

Cycling and Duration Basics

Dose and frequency are two of the three numbers in a protocol. The third is duration, and it varies more than people expect. Growth hormone peptides like sermorelin typically run 3 months on and 1 month off, giving the pituitary axis a reset and creating a natural checkpoint for repeat labs. KLOW runs 6 weeks on and 6 weeks off. Epitalon runs in short 10 to 20 day cycles. Thymosin alpha-1, by contrast, runs continuously with no washout at all, and the GLP-1s are ongoing therapies reviewed at each monthly renewal rather than cycled.

Which peptides need breaks, which do not, and why is a topic with real physiology behind it, and the peptide cycling guide treats it across the whole catalog. If your question is the mirror image, how long a peptide keeps working after a dose, how long peptides stay in your system separates half-life from duration of effect. Both belong next to any dosage chart, because a dose without a schedule and an endpoint is not a protocol.

Peptide Dosage Chart Questions

There is no single typical dose, because peptides span a huge range of potencies. Signaling peptides like BPC-157 and DSIP are dosed in hundreds of micrograms, growth hormone peptides like sermorelin in several hundred micrograms nightly, and larger molecules like glutathione in hundreds of milligrams. The tables on this page give the typical published or clinic pattern for each PeRx peptide, and your provider sets your specific dose within or around those patterns.

It depends entirely on the concentration of the vial. On a U-100 syringe, units = (mg divided by the vial concentration in mg per mL) times 100. At 5 mg/mL, 1 mg is 20 units. At 3 mg/mL, 1 mg is about 33 units. At 200 mg/mL, 1 mg is half a unit. Never borrow a units number from a chart without confirming your vial concentration matches the one the chart assumes.

Almost always because the two charts assume different concentrations. Research-vendor calculators assume you dissolved powder yourself at a strength you chose, while a PeRx vial arrives at a fixed concentration set by the compounding pharmacy and printed on the label. The same milligram dose becomes a different number of units at each concentration, so the charts disagree even when the underlying dose is identical.

No. Providers adjust for body weight, goals, health history, labs, and how you respond over time. The ranges in published protocols exist precisely because different patients land at different points. That is why every row on this page is subordinate to your prescription label, which reflects the decision your provider made for you specifically.

You only need your prescription label. It states the concentration and the dose, usually already expressed as units on an insulin syringe. If you want to double-check the math, divide the dose in mg by the concentration in mg per mL and multiply by 100 to get units. If anything on the label is unclear, call your provider or the pharmacy before drawing anything.

No. GLP-1 dosing is a titration managed by your provider: you start at a conservative strength and the provider adjusts it based on your response and tolerability at each review. The injection itself is typically a small once-weekly draw, 25 units for semaglutide and 50 units for tirzepatide at PeRx, with the strength of the vial doing the changing. These are compounded preparations, not the branded pens, and dosing decisions stay with your provider.

One milligram (mg) equals 1,000 micrograms (mcg). Peptide protocols use both, which makes unit confusion the most dangerous reading error on any chart. A 500 mcg dose is 0.5 mg. If a number seems a thousand times too big or too small compared with another source, check the units before assuming either chart is wrong.

It depends on the peptide. Some run in defined cycles, like sermorelin at 3 months on and 1 month off or KLOW at 6 weeks on and 6 weeks off. Others, like thymosin alpha-1, run continuously. GLP-1 therapy is ongoing and reviewed at each renewal. Your provider sets the duration, and the peptide cycling guide explains the reasoning behind each pattern.

No. The BPC capsule products are fixed-dose capsules taken once daily per your prescription, so there is nothing to draw or convert. The units arithmetic on this page only applies to the injectable products measured with an insulin syringe.

Each row is sourced from the detailed PeRx per-peptide dosing page linked in the table, or from the published typical dosing for products without a dedicated chart. Those pages cite the underlying labels and literature, including FDA reference doses where they exist, such as tesamorelin. This page deliberately adds no numbers of its own.
