I used to exclusively write down my protocols into a peptide diary purchased from Amazon. It is called the Ultimate Peptide Tracker. I loved it for the way it has different calendar views and sections for documenting. Sections were: Peptide Research/Usage Tracker, Source/Vendors, Peptide Weekly Schedule, Monthly Calendar Section and more. However, I found an awesome Excel/Google Sheets template on Etsy. Very inexpensive ($12.99) It is called the "Ultimate Peptide Tracker" by Practical Sheets Co. See images I attached. Kyle, the designer, was also responsive about my desire to add an extra "Diary View" tab, which allows me to assign each of my peptides to its own column. Visually, I can tell at a glance, when it is time to end my peptide cycle(s). It is awesome! By far the best, peptide tracker I could wish for. I paid him an extra $113 to have him do this customization. He also handheld me through some of the hiccups I had understanding how to use it, since I'm not an expert with spreadsheets.
