VialPal
Read full descriptionHide full description
VialPal is a tracker for people following a peptide or GLP-1 protocol who are tired of keeping records in a notes app. LOG A DOSE IN ONE TAP Record every injection as you take it, with reminders so a dose does not quietly get skipped. Your history stays organized by compound and date. VIAL MIXING MATH Enter what is in your vial and how much BAC water you add, and VialPal works out the concentration and how many syringe units match the dose you entered. It is arithmetic on your own numbers: VialPal never suggests what to take, how much, or when. INVENTORY AND VIALS Track what is in the freezer, what is mixed, and what is left. Supply counts update as you log, so you can see when you are running low. SEE YOUR LEVELS Chart estimated peptide levels over time from your own logged doses, and see them alongside weight, sleep, and how you feel. Levels are estimates from published data, not measurements. YOUR DATA IN ONE PLACE See weight trends, side effects, and recovery notes next to your schedule, and bring real records to your next appointment. VialPal is a personal tracking tool. It does not recommend doses or treatments, and it does not provide medical advice, diagnosis, or treatment. It is not a substitute for talking with a qualified healthcare provider. Always follow the guidance of your own clinician. Terms of Use: https://vialpal.app/terms Privacy Policy: https://vialpal.app/privacy

Period tracking is optional β turn it on or off whenever you need. β Wellness forecast A gentle take on how to approach today and the next 7 days. The forecast starts from general conditions like barometric pressure and weather, and as your records build up, it gradually reflects your own patterns too. β Your own data is the strongest evidence Easily log headaches, mood, symptoms, hydration and medication. The symptoms you record most often appear intuitively as larger circles, drawn from your own history. What's been well confirmed is shown under βYour patternsβ; what's still emerging stays under βYour records so far.β Without decoding difficult numbers, you can see at a glance which conditions tended to overlap with your hard days and your calm ones. β Make the look and settings your own Tailor how the app works and looks to suit you.
