Daily, weekly, or something else? Peptide frequency isn't arbitrary — it follows how long each compound lasts in the body.
It depends on the peptide's half-life — how long it stays active in the body. Long-acting peptides like the GLP-1 class are typically studied as once-weekly injections, while shorter-acting compounds such as many growth-hormone-releasing peptides are used daily or several times a day. Frequency is set by the compound and goal, and doses are usually titrated up gradually.

| Peptide type | Typical frequency (as studied) |
|---|---|
| GLP-1 (metabolic) | Once weekly |
| Growth-hormone secretagogues | Daily, sometimes multiple times a day |
| Repair peptides (e.g. BPC-157) | Daily, often through a set cycle |
| Cognitive / sleep peptides | Daily, sometimes as needed |
| Longevity peptides | Often in defined courses rather than continuously |
These are general patterns from how compounds have been studied — not a personal dosing schedule. Your frequency should be set with clinical guidance.
The main driver is half-life — how long the peptide stays active before the body clears it. A long-acting molecule can hold a steady effect from a single weekly dose; a short-acting one needs more frequent dosing to maintain its signal.
That's why you can't apply one peptide's schedule to another. The right rhythm keeps the compound in its effective range without over- or under-dosing.
Beyond half-life, several things influence how often a peptide is used:
It depends on the peptide's half-life. Long-acting peptides like the GLP-1 class are typically weekly; shorter-acting ones like many growth-hormone peptides are daily or more. Frequency should be set with clinical guidance for your specific compound and goal.
Because of half-life — how long the peptide stays active. Long-acting molecules hold an effect from a weekly dose, while short-acting ones need more frequent dosing to maintain their signal.
For some it can — certain growth-hormone peptides are often used around sleep, for example. Timing depends on the compound and goal and is best set with clinical guidance.
An occasional missed dose is rarely serious, but inconsistent, stop-start use blunts and delays results. Follow the schedule set in your protocol rather than doubling up.
Some are used on ongoing schedules and others in defined courses with breaks, depending on the compound. This is educational, not medical advice — a clinician should set the course length.
