Everything in its place

The useful bits. Nothing noisy.

PepSlate is built around day-to-day tracking rather than recommendations. You decide what to record; PepSlate keeps the history organised.

▦
Calendar-first tracking

See scheduled days at a glance and tap any date to review or retrospectively log it.

↻
Real protocol history

Changes create new revisions instead of quietly rewriting what happened previously.

▱
Pens & vials

Link the exact stock item so completed logs update estimated remaining content.

◫
Flexible schedules

Daily, weekly, EOD, 5-on/2-off, selected weekdays and custom intervals.

⌁
Product records

Optional provider, manufacturer, batch and evidence-reference fields stay with the stock item.

⇩
Your own backup

Export and restore your tracker data without needing a health-data account.

∑
Concentration & draw calculator

Enter your own vial/pen amount, liquid volume and intended dose to calculate concentration, draw volume and U-100 syringe markings. It never recommends a dose.

↗
Free research links

Jump to external, source-cited peptide encyclopedias, evidence-focused stacking context and primary research databases without turning PepSlate into a treatment guide.

Simple pricing

No monthly bill.

The free version is genuinely useful. Pro removes the limits with one small lifetime payment.

Privacy boundary

Your tracker isn't an ad profile.

PepSlate has no in-app advertising and no Meta Pixel or behavioural advertising tracker inside the tracker. Protocols, doses, notes and stock records are designed to remain local to the user's device unless they export them.

FAQ

Before you start.

Does PepSlate recommend doses or cycles?

No. PepSlate records schedules and information entered by the user. It does not prescribe or recommend treatment.

Do I need an account?

No tracker account is required for the Free app. Pro purchase restoration uses the checkout email and PepSlate Pro key shown after payment.

Where is my tracker data stored?

Tracker records are local-first in the browser or installed PWA. Keep exported backups of anything important.

Is Pro a subscription?

No. Pro is £4.99 once for lifetime access to the Pro tracker features described at purchase.

Does the calculator tell me what dose to use?

No. You enter the dose yourself. PepSlate only converts the amount, liquid volume and entered dose into concentration and draw measurements.

Does PepSlate publish its own stacking advice?

No. The Research & Guides area links to free external educational sources and primary research so you can inspect current evidence directly.
