About the Peptide Cycle Designer
The Peptide Cycle Designer is a free protocol-building tool that lets you multi-select peptides into a single weekly plan. Pick from BPC-157, TB-500, ipamorelin, CJC-1295 (no-DAC and DAC), GHK-Cu, MOTS-c and epitalon, and the designer lays out a weekly schedule, flags stack synergies, totals your weekly milligrams and suggests cycle-off timing. It is built for people researching recovery, recomposition, anti-aging and longevity protocols who want to see how the pieces fit together before committing. Free, no login.
Read this first: most of these peptides are research compounds, not approved medicines for the uses described here. The doses shown are common community protocols, not approved indications, and human safety data is limited. The designer exists to help you understand how these protocols are structured — it is an educational reference, not medical advice, and not an endorsement to use any compound.
How to use it
Start with a goal preset — injury repair, recomp, anti-aging or longevity — to drop in a sensible starting combination, or skip the presets and select any peptides yourself from the list.
Set your cycle length in weeks. The designer then builds a weekly schedule showing which peptide is dosed on which days, totals the weekly milligrams per compound, and raises a synergy flag whenever you select a known stack.
Use the weekly mg totals to size your vials and plan reconstitution, and read the cycle-off guidance to plan your time between cycles. Nothing here is a prescription — it is a planning layout you confirm with a clinician.
Common stacks
Two combinations come up again and again in the community, and the designer flags both automatically.
- BPC-157 + TB-500 (healing stack): BPC-157 handles localised gut, tendon and ligament repair while TB-500 works more systemically across muscle and connective tissue. Run together, they are the go-to recovery pairing for injury repair.
- Ipamorelin + CJC-1295 (GH-pulse stack): ipamorelin is a selective growth-hormone secretagogue and CJC-1295 (no-DAC) extends and amplifies the same GH pulse. Dosed together — typically pre-bed on an empty stomach — they produce a stronger, cleaner GH release than either alone.
Peptide protocols at a glance
These are the common community starting protocols the designer works from. They are reference points, not prescriptions.
| Peptide | Typical protocol |
|---|---|
| BPC-157 | 250 mcg/day SubQ, 4–6 week course |
| TB-500 | 2.5 mg twice/week loading, then ~2 mg/week |
| Ipamorelin | 250 mcg, 2–3x/day, pre-bed dose |
| CJC-1295 (no-DAC) | 100 mcg with each ipamorelin dose |
| CJC-1295 (DAC) | 1.5 mg, 1–2x/week |
| GHK-Cu | 2 mg/day |
| MOTS-c | 7.5 mg, 2x/week |
| Epitalon | 7.5 mg/day, 10–20 day course |
Cycling and time off
Most peptide protocols are run as time-bound cycles rather than continuously. A common pattern is 8–12 weeks on, then around 4 weeks off, which gives receptors a break and limits desensitisation — especially relevant for GH secretagogues like ipamorelin and CJC-1295.
Some peptides break that pattern. BPC-157 is often a shorter 4–6 week course targeted around a specific injury rather than a long cycle. Epitalon is run as a short 10–20 day course, repeated only once or twice a year, not as an ongoing cycle. The designer surfaces a cycle-off suggestion based on what you select, but the right timing depends on your goal and should be confirmed with a clinician.

Important: read before you use this
This is an educational reference only — it is NOT medical advice. The protocols, schedules and stack flags shown here come from common community practice, not approved indications, and most of these peptides are research compounds with limited human safety data. Nothing here is an endorsement to use any compound. Confirm anything before use and speak with a qualified clinician who knows your full medical history.
