Regimen alternative: an honest comparison with Pepmark
Regimen is the closest app to Pepmark in ambition — peptides, GLP-1s, TRT, big content library. The differences are price (theirs recently rose to $49.99/yr), account model, and how each app treats regulatory truth.
First, credit where due — Regimen does real things well:
- Enormous content library (199 blog posts, 32 web calculators)
- Broad compound coverage like ours
- Serious about answer-engine optimization
Side by side
| Pepmark | Them | |
|---|---|---|
| Accounts | None — no signup, no server | Account-based |
| Where your data lives | On your phone (local SQLite); backup file you own | Cloud-synced |
| Compound coverage | 32 compounds — GLP-1s AND research peptides | Broad: peptides, GLP-1, TRT (29 compound pages) |
| Regulatory labels | Every compound: FDA-approved / 503A / not-compoundable / research-only, with tappable FDA/NIH sources | No per-compound regulatory status labels with citations |
| Dose advice | Never — by design ("does not tell you what to take, or how much") | Positions a deterministic engine; no dosing advice claimed |
| Price | Free core · $2.99/mo · $19.99/yr | $7.99/mo · $49.99/yr (raised from $4.99/$39.99 in 2026) |
Choose Regimen if…
- You want their TRT/HRT content depth
- You use their web calculators daily
- You prefer their intelligence features and are happy at $49.99/yr
Choose Pepmark if…
- You want both worlds in one app — GLP-1 medication tracking and research-peptide protocols, with the regulatory status of every compound labelled and sourced.
- You want privacy by architecture: no account to create, no server that ever sees your medication list.
- You want flat, honest pricing — $19.99/yr, no weekly-price framing, and a free tier that keeps the core forever.
- You want a tracker that refuses to give dosing advice, on purpose.
