Peptides AcademyImmune Support Peptide Stack
A combination approach targeting immune function through three complementary mechanisms: adaptive immune restoration (Thymosin Alpha-1), innate antimicrobial defense (LL-37), and mucosal immune modulation (KPV). This stack addresses both immune surveillance and inflammatory regulation — calibrating rather than blindly boosting immune response.

How to Use Together
The three peptides target different arms of the immune system and can be administered in parallel:
**Thymosin Alpha-1**: 1.6 mg subcutaneous injection, 2× per week. This is the approved dosing schedule (Zadaxin) for immune modulation. Cycles of 8–12 weeks with 4-week breaks. This is the backbone of the stack — the peptide with the deepest clinical evidence.
**LL-37**: 100 mcg subcutaneous injection, 3× per week. Dosing extrapolated from preclinical models — no established human therapeutic protocol. Used for periods of increased infectious risk or active immune challenge. Duration: 2–4 weeks as needed.
**KPV**: 200–500 mcg subcutaneous or oral, daily. The anti-inflammatory component — reduces NF-κB-driven inflammation that can impair immune function. Oral KPV targets intestinal mucosal immunity specifically. Duration: 4–8 weeks.
**Timing**: Thymosin Alpha-1 provides the sustained adaptive immune foundation. LL-37 adds acute antimicrobial support during high-risk periods. KPV modulates inflammatory tone that can suppress effective immune responses.
Safety Notes
This stack combines three research peptides with distinct mechanisms. While each has individual safety data (Thymosin Alpha-1 has the most extensive clinical safety profile), the combination has not been studied. Immune-modulating peptides should be approached with particular caution in individuals with autoimmune conditions, active malignancies, or immunosuppressive therapy — modulating immune function in these contexts can have unpredictable consequences. This is not a substitute for vaccination, appropriate antibiotic therapy, or medical evaluation of recurrent infections.
