Epithalon is a Geroprotective peptide, telomerase activator researched for telomere lengthening, anti-aging effects, improved immune function, melatonin regulation, oxidative stress reduction, cellular rejuvenation.
Mechanism: Interacts with specific DNA sequences (ATTTC) in the telomerase gene promoter, upregulating telomerase expression and activity in somatic cells. Enhances melatonin synthesis and modulation. Influences
Dosage: 5-10 mg daily once daily for 10-20 day cycles via subcutaneous injection or intranasal. Cycle: 10-20 days, repeated 2-3 times per year.
Why it made the list: The only clinically proven telomerase activator with documented human telomere lengthening AND a 1.6x mortality reduction in a 6-year prospective study — the strongest longevity data of any peptide. Read the full Epithalon guide →
#2: KPV — Lysine-Proline-Valine tripeptide
KPV is a Alpha-MSH fragment, NF-κB inhibitor researched for anti-inflammatory, IBD reduction, intestinal barrier repair, skin inflammation reduction, immune modulation.
Mechanism: Inhibits nuclear factor-kappa B (NF-κB) activation through PepT1 transporter-mediated cellular uptake, completely independent of melanocortin receptors. Blocks NF-κB nuclear import and suppresses pro-
Dosage: 200-500 mcg daily once or twice daily via oral (most studied), intranasal, subcutaneous. Cycle: 4-8 weeks.
Why it made the list: The only α-MSH fragment with pure NF-κB inhibition independent of melanocortin receptors — oral bioavailability makes it uniquely practical for gut-targeted anti-inflammatory use. Read the full KPV guide →
#3: LL-37 — Human cathelicidin antimicrobial peptide LL-37
LL-37 is a Antimicrobial peptide, host defense peptide researched for broad-spectrum antimicrobial activity, biofilm disruption, wound healing acceleration, immune enhancement.
Mechanism: Kills pathogens through multiple mechanisms: converts from random coil to α-helix structure, burrows into bacterial membranes causing permeabilization (carpet model), generates oxidative stress in bac
Dosage: 100-500 mcg (topical/local application) topical or local application as needed via topical wound application, local injection, intranasal. Cycle: acute use as needed.
Why it made the list: The human body's own antibiotic peptide with multiple killing mechanisms that prevent bacterial resistance development — unlike conventional antibiotics, bacteria cannot easily evolve resistance to membrane disruption. Read the full LL-37 guide →
#4: Livagen — Lys-Glu-Asp-Ala tetrapeptide
Livagen is a Peptide bioregulator researched for chromatin remodeling, protein synthesis regulation, antioxidant enhancement, liver health support, immune function.
Mechanism: Inhibits enkephalin-degrading enzymes (IC50: 20 μM) and promotes chromatin decondensation to activate silenced genes. Modulates the endogenous opioid system by preventing enkephalin breakdown rather t
Dosage: 200 mcg daily once daily via subcutaneous injection. Cycle: 10-14 day cycles with 6-12 week breaks.
Why it made the list: A true chromatin-remodeling peptide that works through enzyme inhibition rather than receptor activation — mechanistically distinct from nearly every other peptide on the market. Read the full Livagen guide →
#5: N-Acetyl Selank Amidate — N-Acetyl Selank Amidate (stabilized tuftsin derivative)
N-Acetyl Selank Amidate is a Anxiolytic neuropeptide, immunomodulator researched for anxiety reduction, stress resilience, improved mood, cognitive enhancement, immune modulation, BDNF elevation.
Mechanism: Crosses the blood-brain barrier and allosterically modulates GABAergic neurotransmission, enhancing inhibitory tone without direct GABA receptor agonism. Rapidly elevates brain-derived neurotrophic fa
Dosage: 200-600 mcg per dose 1-3 times daily via intranasal spray (most common), subcutaneous injection. Cycle: 14 days on, 1-3 weeks washout.
Why it made the list: Benzodiazepine-like anxiety relief without any dependence, withdrawal, or amnesia — the chemical modifications (N-acetylation + C-amidation) provide enhanced stability over the parent compound. Read the full N-Acetyl Selank Amidate guide →
#6: Thymalin — Thymic peptide bioregulator
Thymalin is a Thymic peptide bioregulator, immunomodulator researched for immune restoration, T-cell maturation, infection recovery, immune deficiency correction, chemotherapy adjuvant.
Mechanism: Constituent short peptides (KE, EW, EDP sequences) specifically bind DNA and histone proteins to regulate gene expression of immune proteins. Stimulates T-cell differentiation and maturation, enhances
Dosage: 10 mg daily once daily (5-10 day cycles) via intramuscular or subcutaneous injection. Cycle: 5-10 days, repeated every 6 months.
Why it made the list: 40-year clinical track record in Russia with exceptional safety — the longest-running immune peptide therapy in clinical use anywhere in the world. Read the full Thymalin guide →
#7: Thymosin Alpha-1 — Thymosin alpha 1 (28-amino acid peptide)
Thymosin Alpha-1 is a Thymic peptide, immunomodulator researched for immune activation, T-cell function enhancement, antiviral response, cancer immunotherapy adjuvant.

Dosage: 1.6-6.4 mg per dose twice weekly via subcutaneous injection. Cycle: 5-7 day injection cycles, repeated as needed.
Why it made the list: The only FDA-approved thymic peptide with specific orphan drug indications — approved in 35 countries, making it the most globally validated immune peptide therapeutic. Read the full Thymosin Alpha-1 guide →
Can You Combine Multiple Immune Peptides?
Stacking complementary peptides for immune is a common research approach. The key is combining compounds with different mechanisms to target multiple pathways without overlapping side effects.
See our stacking and cycling guide for principles on combining peptides safely.
How to Get Started
For beginners, start with a single, well-researched peptide rather than a complex stack. Use our dosing calculator for reconstitution math and our beginner's guide for step-by-step instructions.
Source from vendors with third-party COA testing — quality is the most important factor in achieving consistent research results.
Research-Grade Sourcing
If you're going to research Multiple, source matters. These are the suppliers WolveStack has vetted for purity and third-party testing.
