Peptifact

Peptide Dosage Chart: 29 Compounds and Blends, and the Six Incompatible Units They Are Published In

A dated index of every dose record Peptifact has opened, graded by where the number came from. The chart's own finding is that it cannot be a chart: the published figures for these 29 compounds and blends are stated in at least six units that do not convert into one another.

This page is an index, not a new claim. Every figure it points at was opened, dated and graded on its own page first. What the index adds is the view across all of them at once — and that view produces a finding that the market's dosage charts cannot show, because showing it would break the chart.

The finding is that these numbers are not in the same units, and the differences are not cosmetic.

What the catalogue contains

Twenty-nine compounds and blends have a dated dose record on this site. Classified by the highest tier of source behind any figure on the page:

Tier of best available source Count Compounds
1 — FDA-approved label 5 semaglutide, tirzepatide, bremelanotide (PT-141), elamipretide (SS-31), tesamorelin
2 — human study or registered protocol, no approval 13 NAD+, kisspeptin, retatrutide, cagrilintide, tesofensine, thymosin alpha 1, CJC-1295 (with DAC) and ipamorelin, DSIP, Semax, Selank, GHK-Cu (topical), BPC-157, Melanotan II
4–5 — clinic, vendor or community convention only 11 5-amino-1MQ, AOD-9604, IGF-1 LR3, KPV, TB-500, MOTS-c, epitalon, SLU-PP-332, KLOW, the Wolverine stack, Lipo-C

The tier-2 row is the one to read carefully. It holds compounds with very different amounts of evidence behind the same grade. Thymosin alpha 1 has 66 registrations and 39 randomised trials. Kisspeptin has been infused into healthy volunteers, women with hypothalamic amenorrhoea, IVF patients and men with hypoactive sexual desire disorder, with the doses published to two decimal places. BPC-157's human record is one retrospective series of 12 knee injections with no control group. Melanotan II's is a single registration that has posted nothing. The tier describes the kind of source; only the compound's page describes how much of it exists.

The six units, and why the chart cannot be one number

Here is the obstacle, stated plainly. The dose records in this catalogue are published in at least six forms that do not convert into one another without information a vial label does not carry:

Form the record takes Example from this catalogue What is missing before it becomes a quantity
Flat milligrams Bremelanotide 1.75 mg per dose (Vyleesi label) Nothing — this one is directly usable
Micrograms per kilogram CJC-1295 with DAC, 30–60 mcg/kg A body weight
Nanomoles per kilogram per hour Kisspeptin-54, 1 nmol/kg/h intravenously A body weight, a duration, and a molecular weight to reach mass
USP Units Chorionic gonadotropin, 500–4,000 USP Units A potency-to-mass relationship the vial states and the literature often does not
Percentage of a solution Semax, published as a percentage of a nasal solution A volume instilled
Micrograms per square metre Thymosin alpha 1, 900 mcg/m² twice weekly A body surface area, itself derived from height and weight
A share of a premixed vial KLOW, 50/10/10/10 mg in one vial The vial's ratio — one stated amount fixes the other components

A chart with one number per compound has quietly supplied every missing value in the right-hand column — a weight, a duration, a surface area — and has not told the reader which values it chose. That is the mechanism by which a chart can be composed entirely of real published figures and still be wrong.

The widest spread inside a single molecule illustrates the same problem without leaving tier 1. Semaglutide is labelled in the US across two routes and five separate dose ladders. The lowest labelled figure is 0.25 mg once weekly; the highest is 25 mg once daily. Expressed per week, that is 0.25 mg against 175 mg — a 700-fold range, every point of it approved, for one active ingredient. "Semaglutide dose" is not a question with an answer until the product, the route and the indication are named.

How to use the index

Each row below links to the page that holds the full record: what was administered, to whom, by what route, in what study or under what label, with the dates and registrations. The pages report; they do not recommend, and none of the figures on them is offered as one to use.

Approved labels

  • Semaglutide — four brand names, two routes, five dose ladders, and the label's own statement that two oral products are not interchangeable milligram for milligram.
  • Tirzepatide — two brands at identical strengths with three different ceilings.
  • PT-141 / bremelanotide — 1.75 mg subcutaneously, with two uses the label explicitly excludes.
  • SS-31 / elamipretide — approved in 2025 as FORZINITY at 40 mg once daily; the one compound in this catalogue that moved from research market to label.
  • Tesamorelin and sermorelin — a current label, a withdrawn one, and the compounding convention that filled the gap.

Human studies without approval

  • Kisspeptin — a large, precise record in units no vial label uses.
  • Retatrutide — every circulating figure traces to one trial's arm labels.
  • Cagrilintide — 43 registrations, one sponsor, and most of them study it in combination.
  • Tesofensine — twenty years of trials, four oral doses, no phase 3.
  • Thymosin alpha 1 — the best-evidenced compound on FDA's withdrawn list.
  • CJC-1295 and ipamorelin — two compounds with human studies, and a blend with none.
  • DSIP — every human study used a vein; the market sells a needle.
  • Semax — published figures are concentrations, not milligrams.
  • Selank — two randomised papers in one journal.
  • GHK-Cu — topical concentrations with trials, injectable figures without them.
  • BPC-157 — one uncontrolled retrospective series, and a large body of convention.
  • Melanotan II — one registration, which borrows its design from a programme it is not part of.
  • NAD+ — a 10 mg randomised trial, a 500 mg wellness vial, and nothing connecting the two. Not a peptide.

No human dose record

  • 5-Amino-1MQ — four papers, all in mice or cells.
  • AOD-9604 — more published chemistry on detecting it than on what it does.
  • IGF-1 LR3 — 44 papers, not one a human study.
  • KPV — most of the research is about delivery, not dose.
  • TB-500 — a fragment with no study of its own.
  • MOTS-c — no completed trial, and one registration worth reading.
  • Epitalon — the human studies cited for it were done with a different substance.
  • SLU-PP-332 — sold as a tablet; its developers published that it is not orally available. Not a peptide.

Premixed blends

  • KLOW — four peptides at a fixed 5:1:1:1, so one stated figure sets all four.
  • Wolverine stack — both halves now registered, neither registration stating a dose.
  • Lipo-C — two pharmacies' formulas under one name, four ingredients against eight. Not a peptide.

The field guide

What this index deliberately does not do

It does not average the figures, rank the compounds, or produce a recommended range for anything. Those operations all require the missing values in the table above, and supplying them silently is the defect this page exists to name.

It also does not treat absence as reassurance. Seven compounds here have no human dose record; that is a statement about what has been measured, not a statement about what is safe or unsafe. Where a compound has an approved label, the label is for a stated indication in a stated population, and a figure lifted out of that context stops being a labelled dose.

Anyone reading a dose figure anywhere — here or elsewhere — can apply the same test the dosing-claim guide sets out: what is the quantity and its unit, what route, what frequency, over what duration, and from what source. A figure that cannot answer all five is not yet a dose. Decisions about administering anything to a person belong with a clinician, and nothing on this page is offered in place of that.

Frequently asked questions

Is there a single peptide dosage chart that covers every compound?

Not one that is accurate. The obstacle is not effort but units. Across the 29 dose records indexed here the published figures appear as flat milligram quantities, micrograms per kilogram, nanomoles per kilogram per hour, USP Units, percentage concentrations of a nasal solution, and micrograms per square metre of body surface area. A per-kilogram figure needs a body weight to become a quantity; an hourly rate needs a duration; a percentage needs a volume. A chart that prints one number per compound has silently supplied those missing values, and the values it supplied are not stated anywhere on it.

How many of these compounds have an approved dose?

Five of the 29: semaglutide, tirzepatide, bremelanotide, elamipretide and tesamorelin. Those are the only entries in this index where a dose figure has an approved indication, dose-finding trials and validated reconstitution and storage behind it. Sermorelin is a partial case — its US pediatric label was withdrawn, so the adult figures in circulation are compounding-pharmacy practice rather than labelling.

Which compounds have no human dose record at all?

Seven: 5-amino-1MQ, AOD-9604, IGF-1 LR3, KPV, TB-500, MOTS-c and epitalon. Each was checked individually against DailyMed and ClinicalTrials.gov, with the dates on the compound pages. For these, the figures circulating on clinic, vendor and protocol pages are conventions — repeated, sometimes for years, but never measured in a person and published. Epitalon is the subtlest of the seven: human studies are widely cited for it, but they were conducted with epithalamin, a bovine pineal extract, which is a different substance.

What do the tiers mean?

Peptifact grades every dose figure by how it was found, on six tiers: an FDA-approved label; a trial protocol or peer-reviewed study; a compounding pharmacy's dispensing information; a clinic protocol page; a vendor or protocol site; and a forum post, which this site does not quote. The tiers rank provenance, not truth. A vendor page can correctly report a trial figure, and a label can be for a different use than the reader has in mind. The grade tells the reader which kind of claim they are reading.

Why do two compounds in a peptide index turn out not to be peptides?

Because the catalogue is defined by the channel, not the chemistry. 5-amino-1MQ is 5-amino-1-methylquinolinium, a small-molecule enzyme inhibitor sold as an oral capsule, and tesofensine is a triple monoamine reuptake inhibitor sold as an oral tablet. Both are listed and sold alongside research peptides. Each is flagged on its own page, because a reader who assumes the dosing conventions of one class transfer to the other has made a substitution the chemistry does not support.

Does a higher tier mean a larger body of evidence?

No, and the tier-2 group in this index shows why. It contains kisspeptin, with dozens of published infusion studies across several populations, and thymosin alpha 1, with 66 registrations and 39 randomised trials. It also contains BPC-157, whose human record is a single retrospective series of 12 patients with no control group, and Melanotan II, whose record is one registration that has posted no results. All four sit above an approved label's threshold and below it in every other respect. The tier says what kind of source exists; the compound's own page says how much of it there is.
