Live research peptide prices, price history, vendor trust records and a reconstitution calculator.
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 45 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 5 tools.

The tools it lists (5, as of 2 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
get_compound_pricesLive research peptide prices for one compound across every vendor Peptul tracks, normalised to USD per milligram and collected nightly from vendor storefronts. Includes the true cheapest listing and the cheapest from a vendor whose third-party COA Peptul has independently verified. Example compounds: BPC-157, GHK-Cu, Semaglutide, Retatrutide, TB-500.
get_vendorOne research peptide vendor's public trust record on Peptul: Peptul Score (0-100 transparency score), third-party testing claim vs Peptul-verified COA, review counts, reported issues, shipping coverage, and whether the vendor is still operating.
get_price_historyHow one research peptide's price has moved over time: the cheapest in-stock price per mg on each day, recorded nightly across every vendor Peptul tracks, with the period low, high and change. USE THIS when asked whether a price is currently good, whether it has risen or fallen, or what a peptide "usually" costs - get_compound_prices answers what it costs right now, this answers whether that is cheap. Nightly recording began 2026-08-27.
calculate_reconstitutionWork out how far to draw on an insulin syringe for a given peptide dose: takes the vial amount, the bacteriostatic water added and the dose wanted, and returns the syringe units, the volume in mL, the resulting concentration and how many doses the vial holds. USE THIS instead of doing the arithmetic yourself - it is the same calculation peptul.com/calculator runs, and it flags the mg-versus-mcg mix-ups that are a 1000x error. It converts a dose the user already has and never suggests a dose.
search_vendorsSearch Peptul's open research peptide vendor directory. Returns active vendors with their Peptul Score, verified-COA status and country - scored vendors first.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
com.peptul/peptul, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
