Built with PED and performance experts, Physique Collective. Tracking on its own only tells you what happened. Each week Peakdose reads your own logged data back to you and names what you should do to keep progressing, so you aren't guessing at what to change. - Your week, reviewed. Peakdose weighs your check-ins, weight, training, sleep and stress, then gives you one change to make and shows the evidence behind it. - Plan a whole cycle, and change it mid-cycle. Set doses week by week and adjust as you go without losing your history. - Track your body over time with progress photos, bodyweight, bloodwork and long term health markers. - Advanced analytics lets you see what's working and what it's costing you. - Track side effects including voice deepening, - Export your doses, check-ins and side effects as a CSV. Important Peakdose is a tracking and record keeping tool. It is strictly for prescription medication that has been prescribed to you by a certified medical professional. Peakdose does not give medical advice. It will never tell you what compound to take, what dose to take, or which way to move your protocol. The weekly review only suggests changes to nutrition, training and recovery, based on the data you logged yourself. Always speak to your prescribing clinician before changing anything about your medication.
