Verdict
The clearest difference is rating: Dosebook at 5.0 against Peptide Log's 4.2. Dosebook also leads on monetization model (freemium vs subscription) and update cadence (daily vs every 8 days). Peptide Log's advantage is ratings volume (35 vs 6). On price, ads, in-app purchases and device support there is nothing between them.
