How to Use This Calculator
Enter up to 4 compounds, each with a name, a dose per injection in mcg, a frequency and a timing (AM, PM, pre-sleep or flexible). Click Build Schedule to see a 7-day grid with a colour for each compound, plus the weekly total for each one. Every-other-day patterns assume week 1 starts on a Monday.
Why a Combined Schedule Beats Separate Reminders
Running more than one compound at a time is where timing mistakes tend to happen, not from any single protocol being complicated, but from managing several separately timed reminders that were never laid out against each other. Seeing every compound on one week-view calendar makes it obvious at a glance which days overlap and which are single-compound days, which matters when spacing injection sites or planning around a travel day.
How Each Frequency Falls Across the Week
The builder places every frequency on fixed days of a Monday-to-Sunday week, so you can see how many injections each compound adds to a peptide schedule.
| Frequency | Injections per week | Days used |
|---|---|---|
| Daily | 7 | Mon to Sun |
| Twice daily | 14 | Every day, two injections |
| Every other day | 4 | Mon, Wed, Fri, Sun |
| 3 times a week | 3 | Mon, Wed, Fri |
| 2 times a week | 2 | Mon, Thu |
| Weekly | 1 | Mon |
Keeping the Schedule Accurate
A schedule is only useful if the underlying dose numbers are right. Work out the exact draw for each compound first with the Peptide Dosage Calculator, and if you’re running a full multi-week protocol rather than an open-ended one, the Peptide Protocol Builder extends the same planning across the full cycle length rather than just one week at a time.
Who Should Use This
Researchers running more than one compound who need a single weekly calendar; anyone checking weekly totals across different injection frequencies.
What This Calculator Does
The Multi-Peptide Weekly Schedule Builder lays out up to four compounds on a Monday-to-Sunday calendar. For each compound you set the dose per injection, a frequency (daily, twice daily, every other day, 3× or 2× per week, or weekly) and a timing, and it shows which days each one falls on with a weekly total.
Formula Used
Weekly total (mcg) = Dose per injection × Injections that weekDaily = 7, twice daily = 14, every other day = 4 (Mon, Wed, Fri, Sun), 3× per week = 3 (Mon, Wed, Fri), 2× per week = 2 (Mon, Thu), weekly = 1 (Mon).
Example Calculation
Limitations
Each compound uses one fixed dose and a fixed weekday pattern. It does not model loading phases, dose changes, cycles on and off, or interactions between compounds.
Frequently Asked Questions
How do I make a weekly peptide schedule?
List each compound with its dose per injection and how often it is used, then place the injections on a Monday-to-Sunday calendar. The weekly total for each compound is the dose multiplied by the injections that week. The builder does this for up to four compounds at once.
What is a weekly schedule builder?
A weekly schedule builder lays several compounds out on one 7-day calendar with a colour for each, so you can see which days overlap and what the weekly total is for each compound.
