How to Use the Dosage Schedule Planner
Five inputs generate a complete research injection calendar and vial estimate.
1
Set dose per injectionEnter the mcg amount per injection. This is fixed per injection regardless of how many times per day or week you inject.
2
Choose frequency patternSelect daily, every other day, 5-on/2-off, or 2–3× weekly. Each generates a different weekly calendar pattern.
3
Set cycle lengthEnter how many weeks your research protocol runs. Common lengths are 4, 8, 12, or 16 weeks.
4
Add start dateOptional but recommended. Enables real calendar dates, end date, and a restock reminder 7 days before the cycle ends.
Total injections = Injections per week × Cycle weeks
Total dose (mcg) = Total injections × Dose per injection
Vials needed = ceil(Total dose ÷ Vial size in mcg)
Restock date = Cycle end date − 7 days
Building a peptide dosage schedule for research planning
A peptide dosage schedule defines which days injections occur, how much is administered per injection, and how long the overall research cycle runs. Structuring a clear schedule before starting helps estimate total vials needed, total dose across the cycle, and supply reorder timing.
Common dosing frequency patterns
Daily (7×/week) — highest cumulative dose, simplest to track
5 on / 2 off — Monday through Friday with weekend rest days, popular for peptides with short half-lives
Every other day (EOD) — alternating injection and rest days, approximately 3–4 injections per week
2–3× per week — lower frequency often used for longer half-life peptides or budget optimization
Why cycle length matters
Cycle length directly determines how many vials to purchase and the total budget for a research period. An 8-week cycle at 250 mcg/day requires approximately 14 mg total, or 3 × 5 mg vials. A 12-week cycle at the same dose requires approximately 21 mg, or 5 × 5 mg vials.
Planning restock timing
To avoid running out mid-cycle, plan restock orders 5–7 days before the current cycle ends. This planner highlights the restock date automatically when a start date is entered. Shipping delays vary by supplier, so building in a 7-day buffer is a practical baseline for planning purposes.
Peptide schedule planning FAQ
Common questions about building peptide dosage schedules and research cycle planning.
How do I create a peptide dosage schedule?
Enter dose per injection, frequency, cycle length, and a start date. This planner generates a complete week-by-week calendar showing every injection day, dose amount, and cumulative usage across your full cycle.
What is the 5 on 2 off peptide schedule?
The 5-on/2-off schedule means injecting Monday through Friday with Saturday and Sunday as rest days each week. It provides 5 injections per week while allowing weekend breaks. Select "5 on / 2 off" from the frequency options above to see this pattern in the calendar.
How many vials do I need for a peptide cycle?
Vials needed = Total dose across the cycle (mcg) ÷ Vial size (mcg), rounded up. An 8-week daily cycle at 250 mcg = 56 injections × 250 mcg = 14,000 mcg total. With 5 mg (5,000 mcg) vials: 14,000 ÷ 5,000 = 2.8, so 3 vials needed.
What is a peptide research cycle?
A peptide research cycle is a defined consecutive period of use, typically 4–16 weeks, followed by a planned break. Cycle structure affects total dose, supply requirements, and scheduling. This planner helps map out the full cycle before beginning.
How far in advance should I order peptides?
Order at least 5–7 days before your current supply runs out to account for shipping. This planner calculates a restock reminder date automatically as 7 days before your cycle ends. Set a start date above to see this date for your specific cycle.
