SynergyA PeptidePal alternative that checks your whole stack
Synergy is a PeptidePal alternative that logs peptides, GLP-1 medications, and supplements in one place and checks them against each other. Below: what PeptidePal states it does, what Synergy adds, and what PeptidePal has that Synergy does not. Every fact is from the app's own App Store listing, verified on the date shown.
We make Synergy. "Not stated" means the PeptidePal listing does not mention the feature, not that the app cannot do it. Corrections: [email protected].
What PeptidePal does, in its own words
PeptidePal describes itself as a peptide tracker: dose logging, inventory with low-stock alerts, AM/PM reminders, a reconstitution calculator, half-life tracking with peak notifications, TRT/HGH tracking, a supplement intake and adherence log, health-reaction logging, progress photos and charts, Apple Watch data, CSV export, and encrypted cloud backup.
What Synergy adds
Made for use, not for show
Log it. See where it went. See what it touches.
Supplements, peptides, and GLP-1s in one cabinet
Everything you take is logged in one place — the weekly shot, the peptides, and the supplements — instead of the shot in one app and the rest in a notes file.
Interaction checks across the whole stack
Synergy checks every item against every other and shows the pairs with documented interactions — synergies to lean into, cautions to watch — each with a plain-language, educational summary. Never a dose.
Scan a label to add it
Point the camera at a supplement label and the item is added, free on every plan.
Side effects, narrowed down
Reacting to something while taking four things? The side-effect analyzer works through the timeline and produces a record you can hand to a clinician.
What PeptidePal has that Synergy does not
Half-life tracking with peak notifications, TRT/HGH as a tracked category, and a lower Pro price. Synergy does not model half-lives and does not treat hormones as a category.
