📋 Peptide Dosing Reference Table
Research-grade dosing ranges, frequency, routes, and clinical notes for 23 peptides. Searchable and filterable.
Peptide Dosing Reference
All dosing ranges are sourced from published pre-clinical research, translational protocols, and established practitioner guidelines. Ranges represent the span seen across research contexts — not a single prescriptive dose. Use the search to filter by peptide name, category (e.g. GH Peptides), or route (e.g. SC, Intranasal).
| Peptide | Category | Dose Range | Frequency | Route | Research Notes |

Peptide Reference — Frequently Asked Questions
Why do dose ranges vary so widely for some peptides?
Dose ranges reflect the full span of doses used across different research contexts — from conservative introductory doses to higher doses used in specific therapeutic models. For example, TB-500's 2,000–10,000 mcg range covers both a low-dose chronic maintenance protocol and a higher-dose acute loading phase. The appropriate dose for any individual depends on the specific research goal, body weight, protocol phase (loading vs. maintenance), and observed tolerability. Starting at the lower end and adjusting based on response is standard research practice.
What does "fasted" timing mean in practice?
"Fasted" means at least 2–3 hours after your last meal, and ideally 8+ hours fasted (e.g. first thing in the morning before breakfast). Fasted administration is most important for growth hormone-releasing peptides (GHRPs, CJC-1295, Ipamorelin) because elevated blood glucose and insulin suppress the GH response. For BPC-157 and other tissue-repair peptides, the fasted vs. fed timing is less critical, though many protocols still recommend it for consistency.
Can I adjust frequency without changing dose?
Yes, and this is a common protocol adjustment. For example, reducing CJC-1295 + Ipamorelin from 3× daily to 1× daily at bedtime significantly reduces cost and injection burden while preserving meaningful GH pulsatility benefits. The trade-off is between peak GH pulse frequency and convenience. For BPC-157, moving from twice daily to once daily at a slightly higher dose is often used when daily compliance is challenging. Consult specific peptide research for frequency-response relationships before modifying a protocol.
How do I use this table with the other calculators?
This table is the starting point for all other calculator inputs. Find your peptide here to get the dose range and frequency, then: (1) Use the Reconstitution Calculator with your vial size to find concentration and draw volumes. (2) Use the Vial Duration Calculator with your dose and frequency to check 28-day expiry. (3) Use the Cost Calculator to budget your cycle. (4) Use the Protocol Builder to schedule multiple peptides.
