Cycle Duration Estimator

Plan by duration to size a protocol, or plan by supply to see how long the vials on hand will last. Arithmetic only — never a schedule.

How this works

Each frequency converts to injections/week (e.g. every-other-day = 3.5/week). In duration mode, injections/week is scaled by the number of weeks to get total injections, and total mass is either injections × dose, or the sum of each loading/maintenance phase's own weeks × dose. In supply mode, total mass comes from vials on hand × vial mass, which is divided by dose to get total injections, then converted back to days/weeks using the same injections/week figure.

Buffer % applies only when rounding up to whole vials needed — it never changes the total mass or injection count reported above.

Category reference (non-prescriptive)

GH secretagogues: Research protocols for GH-secretagogue peptides (Ipamorelin, CJC-1295) are commonly described in multi-week blocks with breaks. Reference only — not a schedule.

Healing / recovery peptides: Recovery-research peptides (BPC-157, TB-500) appear in the literature over defined multi-week windows. Reference only — not a schedule.

Metabolic (GLP-1 class): GLP-1-class compounds are approved drugs with label-defined titration. Consult the label and a clinician — this tool does arithmetic only.

Reference arithmetic for laboratory sample handling only. This is not dosing guidance and not medical advice.
