Founding price. When they are gone, lifetime closes.
Keep what you read, and the studies behind it.
Everything you save lands in your notebook, where you can search it, filter it and export it.
Unlimited saves
Bookmark any guide, compound page, comparison or research record. A free account keeps 3. Pro keeps everything.
Highlights and notes
Highlight a passage as you read and keep your own notes beside anything you saved.
Notebook export
Download your saved items and results as an Excel workbook, even on a free account. Pro exports include your highlights and notes too.
Research records
Search every paper and registered trial for 383 compounds by species, study type and year. Read the open access ones here, in full, and open the rest at their source.
Species and study filters
Narrow what you find by species, study type and year, so animal work doesn't crowd out the human evidence.
Sorted by citations
Put the most-cited work at the top, or flip to the newest, when you want the strongest paper first.
If you keep your own plans, these do the bookkeeping.
Doses, schedule, supply and spend, worked out from your own numbers.
Unlimited plans
Save every peptide you research with its dose, syringe draw and cost per dose worked out. Change the dose and everything recalculates. A free account keeps 1 saved plan in My Peptides.
Schedule
Lay your doses out on a weekly calendar, log what you took, and see at a glance when nothing was doubled or missed.
Inventory runway
Track what you have on hand, see the date you run out at your current dose, and get a reorder date before it matters.
Stack builder
Check any combination for doubled compounds and shared targets, with each compound's evidence level and current price beside it.
Saved stacks
Keep your combinations with live vendor pricing and the monthly cost of the whole group in one place.
Vendor comparison
Rank vendors by real cost per mg from the prices you enter, including the ones no public list carries.
Spend history
See what you have spent by compound and by month, and catch drift before it becomes a habit.
CSV exports
Export any stack or plan to a spreadsheet for your own records or your clinician.
Still deciding?
Start with a free account. It keeps 3 notebook saves and 1 saved plan in My Peptides, with Excel notebook exports included.
Can I cancel my subscription?
Yes. Monthly and annual plans can be canceled anytime from your account. Lifetime is a one-time purchase.
What do I get without paying?
The guides, compound pages, evidence pages, dose calculator, unit converter, vial-life calculator, cost per mg, compare tool and legal status table are all free and need no account. A free account adds 3 notebook saves, 1 saved plan in My Peptides and Excel notebook exports. Pro removes both save limits and adds highlights and notes, the record-level research search, the schedule, inventory, stacks, vendor comparison, spend history and planning exports.
What happens to my saved data if I downgrade?
Nothing is deleted. Your saved peptides, stacks, inventory, vendors, schedule, notebook and spend history stay in your account as read-only, and everything unlocks again the moment you resubscribe.
