Research-use peptide reconstitution & dosing calculators for 15 compounds. Not medical advice.

What it does

PeptideLab Calculator is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

ONLINE PeptideLab Calculator answered an MCP connection on 21 Oct 2026 and introduced itself as peptidelab-mcp 0.1.0 (MCP protocol 2025-06-18).

6 tools offered to AI assistants

calc_reconstitution · Calculate peptide reconstitution: concentration, draw volume, syringe units and doses per vial. Forward mode: dose_mcg. Reverse mode: pass dose_units to back-solve the dose. Returns precision (parallax) warnings, syringe overflow checks and
list_peptides · List or search the curated research peptide dataset (ids, names, aliases, categories, confidence grades, common dosing windows). Research use only.
get_protocol · Get the full research protocol record for one peptide: dosing window, frequency, cycle, titration ladder (GLP-1 class), special notes and confidence grade. Research use only.
plan_schedule · Generate a week-by-week research schedule: frequency presets (daily / 1-3x weekly), GLP-1 style titration ladders and optional syringe-unit readouts per event. On-demand compounds return an advisory instead of a calendar. Research use only.
plan_stack · Plan a multi-compound stack: per-compound draw volumes and units, combined draw volume with split-injection advisories, and frequency-conflict detection. Research use only.
compare_syringes · Compare U-100 and U-40 syringes for one target dose: units required, fit and relative reading error (parallax risk). Sorted best-first. Research use only.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
