PhysiqueOS keeps dose logs, reminders, inventory, and progress notes together when your protocol gets too detailed for screenshots or spreadsheets.

Add each peptide with its dose and schedule, and the summary above computes injections per week, estimated weekly cost, and estimated monthly cost. The weekly schedule table lays out which compound goes on which day, which is where scheduling conflicts become obvious in a way they never are in your head.
Cost estimates use the vial price you enter and the number of doses that vial yields at your chosen concentration. That means the figure updates when you change reconstitution volume, because a different concentration changes how many doses come out of the same vial. If you want to sanity check a single peptide's math first, the reconstitution calculator shows the underlying numbers.
Injection load. Compounds dosed two or three times daily add up fast when stacked. Three peptides at twice daily is six injections a day, which is a very different commitment from a single weekly injection. Seeing that number before starting is the point.
Timing conflicts. Some compounds have timing requirements that constrain everything around them. Growth hormone secretagogues are typically taken on an empty stomach and away from other food, which limits where they fit in a day. Stacking two compounds with incompatible timing requirements is a planning problem that only shows up on a calendar.
Vial burn rate. Knowing that one vial covers 10 doses tells you when to reorder. Running out mid-protocol is a common and entirely avoidable disruption, and it is the reason the doses-per-vial figure sits next to the cost figure.
True cost. Per-vial price is misleading on its own. A cheaper vial that yields fewer doses at your target dose can cost more per week than an expensive one. The builder normalizes this to a weekly and monthly number so the comparison is like for like. Current supplier pricing is on the price comparison board.
This tool does arithmetic. It does not evaluate whether a protocol is sensible, safe, or appropriate for any person, and it has no way to assess interactions between compounds.
It assumes each vial contains exactly what its label states, at the stated purity. For research-supply material that assumption is not verified by anyone, and if it is wrong then every downstream number, dose, cost, and doses-per-vial, is wrong by the same factor.
It also assumes you follow the schedule you enter. Real adherence varies, and a plan built around six injections a day is a plan with more opportunity to drift than one built around one a week. That is worth weighing at the planning stage rather than discovering in week three.
