Peptide Dosage Chart & Guide

The following peptide dosage chart compiles commonly referenced research dosage ranges for the most popular peptides. This peptide dosing guide covers subcutaneous, oral, and intranasal compounds with typical dose ranges, frequency, and timing. All dosages are for research reference only — consult a healthcare provider before using any peptide.

Peptide	Typical Research Dose	Frequency	Route	Timing Notes
BPC-157	200-500 mcg/day	1-2x daily	SubQ or oral	Can split into AM/PM doses. SubQ near injury site when targeting specific area
TB-500	2-5 mg/week (loading), 2 mg/week (maintenance)	2-3x weekly	SubQ	Loading phase (4-6 weeks) followed by lower maintenance dose
GHK-Cu	100-500 mcg/day (injectable) or 1-3% topical	1x daily	SubQ or topical	Topical for skin/hair. Injectable for systemic effects
Sermorelin	100-300 mcg/day	1x daily	SubQ	Before bed on empty stomach (aligns with GH surge)
Ipamorelin	100-300 mcg/dose	2-3x daily	SubQ	On empty stomach. Often combined with CJC-1295
CJC-1295 (no DAC)	100-300 mcg/dose	2-3x daily	SubQ	Often stacked with ipamorelin for synergistic GH release
CJC-1295 (with DAC)	1-2 mg/week	1-2x weekly	SubQ	DAC extends half-life, allowing less frequent dosing
Tesamorelin	2 mg/day (FDA-approved dose)	1x daily	SubQ	Evening administration. FDA-approved dose is well-established
AOD-9604	250-500 mcg/day	1x daily	SubQ	Morning on empty stomach (fasted state)
PT-141 (Bremelanotide)	1.75 mg/dose (FDA-approved dose)	As needed, max 1x per 24 hours	SubQ	45 min before activity. Max 8 doses/month. FDA-approved for HSDD
MK-677	10-25 mg/day	1x daily	Oral	Can cause hunger — many take before bed to sleep through appetite spike
Semax	200-600 mcg/day	1-3x daily	Intranasal	Morning dosing preferred. 200 mcg is the standard Russian clinical dose
Selank	250-750 mcg/day	1-3x daily	Intranasal	Can be taken morning or evening. Anxiolytic effects
KPV	200-500 mcg/day	1-2x daily	SubQ or oral	Oral for gut inflammation. SubQ for systemic effects
Epitalon	5-10 mg/day	1x daily (10-20 day courses)	SubQ	Cycled 2-3x per year in 10-20 day protocols

Note: All peptide dosages listed in this chart are based on published research protocols and clinical trial data. They are provided for educational reference only and do not constitute medical advice. Individual dosing should be determined by a qualified healthcare provider based on your specific circumstances.

• Start low: Begin at the lower end of the research dose range to assess tolerance before increasing
• Consistency matters: Most peptide effects are cumulative. Consistent daily dosing over weeks is more important than any single dose
• Cycling: Many protocols include rest periods (e.g., 5 days on, 2 days off, or 4 weeks on, 2 weeks off) to prevent receptor desensitization and maintain effectiveness
• Empty stomach: GH secretagogues and fat-loss peptides are typically more effective on an empty stomach (no food for 2+ hours before and 30 minutes after)
• Timing with GH pulse: For peptides that stimulate GH release, evening/bedtime dosing aligns with the body's natural nighttime GH surge

Some peptide protocols reference doses on a per-kilogram body weight basis (mcg/kg). This is particularly common in animal research that is extrapolated to human dosing. For research peptides, most human protocols use fixed doses rather than weight-adjusted doses.

Notable exceptions:

• BPC-157: Some research references 1-10 mcg/kg/day, though most human protocols use fixed doses of 200-500 mcg
• GLP-1 agonists: FDA-approved doses are fixed (not weight-based) but are titrated up over time

Our dosage calculator can adjust standard ranges for body weight if you prefer weight-based dosing.
