    Peptide Dosing Guide: Beginner to Advanced Protocols

    Peptide dosing is not one-size-fits-all. The right dose depends on the compound, the research goal, the delivery method, and the individual's tolerance. This guide organizes the most commonly researched peptides into beginner and advanced categories, covers injectable vs. nasal delivery, and provides practical dosing charts with protocol structures.

    Safety Disclaimer — Read Before Continuing

    • All dosing information is for educational and research purposes only. These are not medical recommendations.
    • Peptides should only be used under the supervision of a licensed healthcare provider.
    • Doses listed reflect ranges reported in research literature and community protocols — individual response varies significantly.
    • Never self-administer any compound without understanding its mechanism, risks, and contraindications.

    Beginner Peptide Protocols

    Beginner-friendly peptides share a few key traits: a well-understood safety profile from research literature, low hormone interaction, straightforward dosing, and forgiving pharmacokinetics. If you're new to peptide research, start with one compound before adding others.

    Beginner protocols typically run 6–8 weeks. Start at the low end of the dose range and assess for 1–2 weeks before adjusting.
    PeptideDoseFrequencyRoute
    BPC-157250 mcgOnce dailySubcutaneous or IM
    Ipamorelin100–200 mcg2–3x dailySubcutaneous
    CJC-1295 (no DAC)100–200 mcg2–3x dailySubcutaneous
    Epithalon5–10 mgOnce dailySubcutaneous
    TB-500 (Thymosin Beta-4)2–5 mg2x per weekSubcutaneous or IM

    BPC-157: Start low — some begin at 150 mcg. Highly tolerated. Good entry point for healing protocols.

    Ipamorelin: GHRP with minimal side effects. Often stacked with CJC-1295. Ideal first growth hormone secretagogue.

    CJC-1295 (no DAC): Short-acting GHRH — pair with Ipamorelin for synergistic GH pulse. Well-studied and beginner-friendly.

    Epithalon: Telomere-supporting tetrapeptide. Commonly run as a 10-day cycle. Very low side effect profile.

    TB-500 (Thymosin Beta-4): Often paired with BPC-157 for connective tissue and injury recovery. No hormonal mechanism.

    Advanced Peptide Protocols

    Advanced peptides typically involve stronger hormonal interactions, more complex titration schedules, or a narrower margin between effective and excessive dosing. These are for researchers with established experience managing peptide protocols and who understand the relevant physiology.

    Advanced protocols require careful titration and ideally bloodwork-based monitoring (IGF-1, HbA1c, fasting glucose where relevant).
    PeptideDoseFrequencyRoute
    Tesamorelin1–2 mgOnce dailySubcutaneous
    Retatrutide0.5–4 mg (titrated)Once weeklySubcutaneous
    Semaglutide0.25–2.4 mg (titrated)Once weeklySubcutaneous
    Dihexa10–30 mgOnce dailyOral or transdermal
    IGF-1 LR320–50 mcgOnce daily (post-workout)Subcutaneous or IM

    Tesamorelin: GHRH analog — FDA-approved for HIV lipodystrophy. Potent GH stimulator. Requires cycle management.

    Retatrutide: Triple agonist (GLP-1/GIP/glucagon). Requires careful titration — start at lowest effective dose and escalate slowly.

    Semaglutide: GLP-1 agonist. Requires slow titration over 16–20 weeks. Nausea common at higher doses without proper escalation.

    Dihexa: Potent nootropic — extremely high activity relative to dose. Use the lower end of the range. Not for beginners.

    IGF-1 LR3: Requires precise timing and dose management. Hypoglycemia risk. Cycle 4 weeks on, 4 weeks off minimum.

    Nasal Spray Peptides: Needle-Free Delivery

    Several peptides — particularly those targeting cognitive function, mood, or sexual health — are well-suited to intranasal delivery. The nasal mucosa provides direct access to cerebral circulation via the olfactory epithelium, which can make nasal delivery particularly effective for peptides targeting the central nervous system.

    Nasal vs Injectable Bioavailability

    Intranasal bioavailability is generally lower than subcutaneous injection, but for CNS-targeted peptides this tradeoff may be favorable due to direct transport across the blood-brain barrier. Doses for nasal delivery are often higher than injectable equivalents to compensate.

    PeptideNasal DoseFrequency
    Semax200–600 mcg1–2x daily
    Selank250–500 mcg1–3x daily
    PT-141 (Bremelanotide)0.5–2 mgAs needed (1–2 hrs pre)
    Epitalon (nasal)1–3 mg per nostril1–2x daily

    Semax: ACTH analog with neuroprotective and cognitive-enhancing properties. Available as nasal spray. Onset within 30–60 minutes.

    Selank: Anxiolytic and nootropic peptide. Gentle, well-tolerated. Can be used as-needed or on a daily protocol.

    PT-141 (Bremelanotide): Melanocortin receptor agonist used for sexual function research. Nasal delivery achieves rapid onset. Also available injectable.

    Epitalon (nasal): Nasal administration is an alternative to subcutaneous injection. Some researchers find equivalent bioavailability.

    Universal Dosing Principles

    Start Low, Go Slow

    Begin at the lowest published dose and assess tolerance before increasing. Many peptides have a dose-response curve that plateaus — more is not always better.

    Time Injections Strategically

    GHRPs and GHRHs (Ipamorelin, CJC-1295, Tesamorelin) are most effective when dosed before sleep or fasted in the morning. Insulin levels blunt GH response — avoid dosing after meals.

    Use Cycles, Not Indefinite Runs

    Most peptide protocols are run in cycles (6–12 weeks on, 4+ weeks off) to prevent receptor desensitization and maintain efficacy. GLP-1 agonists like Semaglutide are exceptions with longer continuous use studied.

    Rotate Injection Sites

    Subcutaneous injections should rotate across sites — abdomen, thigh, deltoid — to prevent lipohypertrophy and tissue buildup at any single location.

    Match the Peptide to the Goal

    BPC-157 and TB-500 for recovery. GHRPs/GHRHs for growth hormone and body composition. GLP-1 agonists for metabolic/weight research. Nootropic peptides for cognitive protocols. Stacking works best within goal-aligned categories.

    Injectable Safety Guidelines

    Sterile Technique

    ✓ Always swab the rubber stopper with 70% isopropyl alcohol

    ✓ Use a new needle for every injection — never reuse

    ✓ Work on a clean surface

    ✓ Never share needles or vials

    ✓ Dispose of sharps in a proper sharps container

    Injection Technique

    ✓ Subcutaneous: 45° angle, pinch skin, inject into fat layer

    ✓ Intramuscular: 90° angle, larger muscle groups

    ✓ Rotate sites each injection

    ✓ Inject slowly — 10–15 seconds

    ✓ Apply gentle pressure after — don't rub
