Fake, recycled and mismatched peptide COAs: how to spot forged documents, reused certificates, and the far more common genuine-COA-wrong-batch failure.
2026-08-03
How to read a peptide COA field by field: lot and batch numbers, HPLC purity, mass spec identity, and the net peptide content line almost nobody checks.

How to find A2LA-accredited labs and verify any peptide testing lab: what ISO 17025 accreditation covers, how to search the A2LA and ILAC directories, and why contacting the lab directly matters.

Most peptide trackers are US-built. What European users should check — language support, GDPR rights, on-device health data — and how the apps compare.
2026-07-29
A tracking system that actually holds up: inventory with lot numbers, scheduled panels, wearable context, and clean records — with or without an app.

Peptide Log is iOS-only and diary-focused. Here are seven alternatives — including Android options and trackers that add verification, blood work and wearables.
2026-07-29
Peptide Log is a clean iOS dose diary. Peppies is an Android-first inventory, blood-work and wearable tracker with COA verification. Which fits your routine?
2026-07-29
A certificate of analysis is the only evidence of what's actually in a vial. What COAs are, how third-party verification works, and which tracker builds it in.

Regimen leads the dose-tracker category — but if you need batch verification, blood work, a free app, or iOS simplicity, these alternatives fit better.
2026-07-29
Regimen is the category's best dose-and-protocol tracker; Peppies is an inventory, blood-work and wearable log with batch verification. An honest head-to-head.
