Free peptide research tools

Stop guessing. The numbers are already worked out.

PepDosings exists because the answers to the most basic peptide questions are scattered across forum posts, sales pages and half remembered screenshots, and almost none of them show their working. Every tool here is built on a maintained database and published research, every figure is on the screen where you can check it, and nothing asks you to make an account or hand over an email address first. Three tools cover the ground: what a compound is and how it is dosed, what your own body actually needs, and what changed in the field this morning.

Peptide Reference Guide

The most complete peptide reference on the internet.

Every compound gets the same five sections: what it is and what it does, how it is dosed and titrated, what the safety picture looks like, what it can and cannot be combined with, and how it behaves in the body over time. Pick a compound, enter your vial size and how much bacteriostatic water you added, and the guide returns the concentration along with the exact pull on a U-100 syringe for every single step of the schedule. Set a plan length in weeks and it totals up what you will need.

  • 122 compounds across 12 categories, from the GLP-1 class through the growth hormone axis to bioregulators
  • 397 titration schedules broken into 883 individual steps, with real doses rather than vague ranges
  • 9,784 compatibility pairs, so you find out what stacks and what fights before you buy anything
  • 1,222 documented side effects and 1,139 contraindications, cited rather than asserted

TDEE and Macro Calculator

The most honest calorie and macro calculator on the internet.

Most calculators will happily hand you a number that would starve you, because they multiply and divide without ever asking whether the answer is survivable. This one refuses. It works out your resting burn with the Mifflin St Jeor equation, scales it by how you actually spend your week, applies your goal, and then holds a hard floor underneath the result. You get your calorie target and your protein, carbohydrate and fat split in grams, and you can lay all four diet presets beside one another to see what each would really mean at breakfast.

  • Mifflin St Jeor, the equation with the strongest track record against measured metabolic rate
  • Five activity levels, from sedentary through to extra active, applied to the resting figure
  • Four diet presets, balanced, high protein, low carb and keto, compared side by side, plus custom ratios
  • A safe floor that will not return a target below 1,500 calories for men or 1,200 for women, whatever you ask it for
Mifflin St Jeor 4 diet presets 5 activity levels 1,500 / 1,200 safe floor

Peptide Industry News Desk

The best peptide news desk on the internet.

Every morning the wire reads the regulators, the trial registries, the journals, the preprint servers, the trade press and the investor relations feeds of the companies whose results move this whole field, then sorts what it found into categories you can actually navigate. It is the only place that tracks grey market activity and enforcement action in the same view as the clinical literature, which matters because in this corner of the world a warning letter is often the news that affects you first.

  • 33 sources read every morning, including the FDA, openFDA, ClinicalTrials.gov, PubMed, bioRxiv, medRxiv, the EMA, the MHRA, Health Canada and the TGA
  • Eight categories covering grey market, enforcement, foreign coverage, trials, regulatory action, research, industry and general news
  • Every item has to match peptide relevant keywords before it is stored, so the feed stays on subject
  • No social media and no Reddit, because a rumour repeated loudly is still a rumour

Open Peptide Wire

All three are free, and they stay free

There is no account to create, no trial to start and no email address to surrender. Nothing here is hidden behind a subscription and nothing is held back for a paid tier, because a reference that only answers half a question is not a reference. Open whichever tool answers the question you arrived with, and come back to the wire in the morning.
