Goal-based protocols built on evidence — not guesswork. Whether you're starting your first cycle or building a comprehensive stack, this is your reference guide.
Start Here → Browse by GoalProtocols without context are just lists. Here's what you actually need to understand first.
A peptide protocol is a structured plan that defines which peptide(s) you use, at what dose, how often, how it's administered, and for how long. Unlike taking a daily vitamin, peptides are typically run in cycles — periods of use followed by rest — to maintain receptor sensitivity and biological effectiveness.
Good protocols balance efficacy with safety: starting conservatively, monitoring response, and adjusting based on what your body actually does — not what a forum says should happen.
Most peptides used in wellness contexts exist in a gray zone: promising animal research, limited human clinical trials, and a growing body of anecdotal evidence. When we describe protocols here, we note the evidence grade — what's well-studied versus what's emerging or largely anecdotal.
This matters because evidence grade should influence how conservatively you approach a compound. A peptide with only rodent data warrants more caution than one with Phase II clinical trials.
Purity matters enormously with peptides. A "99% pure" claim from a low-quality lab may still contain problematic impurities. Key sourcing principles:
We'll say it plainly: a conversation with a qualified healthcare provider — ideally one familiar with peptide therapy — is the highest-value step before starting any protocol. Not because it's legally required, but because individual health contexts vary dramatically. Bloodwork (IGF-1, inflammatory markers, liver function) gives you a baseline to track against.
This is especially true for peptides that influence growth hormone, metabolic function, or the endocrine system.
Each protocol is built around a specific goal with evidence-graded recommendations, typical dosing ranges, and cycle structures.
Accelerate healing of tendons, ligaments, muscle tissue, and gut. BPC-157 + TB-500 is the most well-documented combination in this category, with strong animal data and extensive anecdotal use.
Epigenetic reset, telomere support, mitochondrial function. Epithalon leads the category with the strongest longevity-specific research in the peptide space.
Focus, anxiety reduction, and neuroprotection. Selank and Semax have the strongest evidence base in this category, with legitimate clinical use in Russia and the former Soviet states.
GLP-1 receptor agonists have the strongest evidence base of any compounds in this guide. Semaglutide and tirzepatide have completed Phase III trials. Retatrutide — a next-generation triple agonist (GLP-1/GIP/glucagon) — showed 24.2% weight loss in Phase 2 trials and is currently in Phase 3. All require prescriber oversight.
AOD-9604 is the lipolytic fragment of human growth hormone (amino acids 176–191), engineered to stimulate fat oxidation and inhibit new fat storage — without raising IGF-1 or blood glucose. Phase II trials showed modest benefit; Phase III missed its endpoint. Best used as a complement to a calorie deficit, not a replacement for one.
Collagen remodeling, wound healing, and hair restoration. GHK-Cu has the deepest research base for topical use. Combine with systemic peptides for comprehensive skin health support.
GHRH/GHRP peptides stimulate pulsatile GH release naturally. Sermorelin is the gold standard for age-related GH decline; the CJC/Ipamorelin stack is the most widely used combination for body composition.
Restore gut lining integrity, reduce inflammation, and support healthy digestion. BPC-157 has remarkable oral bioavailability for gut-specific applications — one of the few peptides where oral administration is well-documented.
KPV (Lysine-Proline-Valine) is the anti-inflammatory tripeptide fragment of alpha-MSH. It directly inhibits NF-κB signaling in gut epithelial cells, making it uniquely suited for IBD, Crohn's, colitis, and leaky gut. Its small size allows oral bioavailability — one of few peptides that works well taken by mouth for gut-specific targets. Stacks exceptionally with BPC-157 for synergistic gut healing.
Support immune system function, reduce susceptibility to infection, and enhance overall resilience. Thymic peptides have the deepest evidence base, with Thymosin Alpha 1 approved as a pharmaceutical in several countries.
MOTS-c is a mitochondria-encoded peptide that activates AMPK via the folate cycle — triggering insulin-independent glucose uptake, fat oxidation, and mitochondrial biogenesis. Called an "exercise mimetic" for its overlap with aerobic exercise signaling. WADA-prohibited since 2024. Research-stage only; no validated human protocol exists.
Thymosin Alpha-1 (Tα1) is the most clinically validated immune-modulating peptide in the world. Approved in 35+ countries as Zadaxin for hepatitis B/C and cancer immunoadjuvant therapy. Three distinct protocol options: immune maintenance, active immune challenge, and stacking with TB-500 for recovery + immune defense.
PT-141 (bremelanotide/Vyleesi) is the only FDA-approved peptide for sexual dysfunction — specifically HSDD (hypoactive sexual desire disorder) in premenopausal women. Unlike PDE5 inhibitors (Viagra, Cialis), it works centrally via melanocortin receptors in the brain rather than on blood vessels. Also used off-label in men for desire and arousal support.
Stacking — running multiple peptides simultaneously — can amplify results, but introduces complexity. Each added compound is another variable to track. The principle: establish one peptide's baseline effects before adding another.
Run your primary compound alone for one full cycle. Understand how you respond before introducing a second variable. This is how you actually know what's working.
Stack compounds with different mechanisms of action. BPC-157 (local healing) + TB-500 (systemic actin regulation) work synergistically precisely because they act via different pathways.
When stacking, a daily log is not optional. Dose, time, site, any effects. If something goes wrong, you need to know which compound is the likely cause so you can drop it.

This section is prominent for a reason. Contraindications aren't disclaimers — they're information you need.
Cycling prevents receptor desensitization, supports natural hormone rhythms, and gives you built-in checkpoints to evaluate effectiveness.
Recovery protocol — acute injury or chronic issues
BPC-157: 500 mcg/day (250 mcg AM + PM). TB-500: 2.5 mg twice weekly. Inject near injury site where possible.
BPC-157: 250 mcg/day. TB-500: 1 mg weekly. Assess injury progress. Many users see significant improvement by week 6.
Complete break. Allow natural tissue remodeling. Continue physical therapy if applicable. Reassess before next cycle.
GH optimization — body composition and recovery
CJC-1295 (no DAC) 100 mcg + Ipamorelin 100 mcg, SC 2–3×/day. Bedtime dose is most important. Results emerge at 6–8 weeks.
Full break for one month. Test IGF-1. Allow somatostatin receptor sensitivity to restore. Evaluate whether to continue.
Restart if bloodwork is appropriate and goals remain. Many people run 5-on/1-off indefinitely under provider supervision.
Longevity course — annual or semi-annual
5–10 mg/day SC. Can split into AM/PM doses. Most people use the full 20-day course; 10 days is the minimum cited in research.
No Epithalon. Continue other health practices. Epithalon's epigenetic effects are proposed to have lasting duration.
Second 10–20 day course. Most protocols recommend 1–2 courses per year. Some research suggests twice annually for maximum benefit.
Nootropic protocol — focused on cognitive goals
250–1000 mcg intranasal, 1–2×/day. Leads with anxiolytic and GABA-modulating effects. Best for stress, baseline anxiety, focus foundation.
10-day break. Allow neuroreceptor normalization. Use this window to assess which effects were peptide-derived vs. placebo/lifestyle.
200–600 mcg intranasal, AM dose. BDNF-stimulating, focus and memory consolidation. More stimulating than Selank — avoid late dosing.
