BPC-157
A healing compound from human gastric juice. The most extensively studied repair peptide in animal models, with strong preclinical data for tissue repair, gut restoration, and anti-inflammatory effects. Human clinical data remains limited.
KPV
Three-amino-acid anti-inflammatory peptide especially effective for gut inflammation. Go-to for IBD and inflammatory gut issues. Also calms systemic inflammation.
BPC-157 Arginine Salt (Oral Stable Form)
Oral-stable BPC-157 formulation using arginine salt for bioavailability. Delivers peptide directly to the GI tract for localized gut healing without injections.
Larazotide Acetate
Tightens seals between gut lining cells, directly addressing leaky gut. Developed for celiac disease but useful for gut barrier problems broadly.
BPC-157/TB-500 Blend
Pre-mixed BPC-157 + TB-500 healing combo. Combines targeted tissue repair with systemic healing, amplifying anti-inflammatory and regenerative effects.
VIP (Vasoactive Intestinal Peptide)
Neuropeptide with powerful anti-inflammatory properties. Widely used in mold illness (CIRS) protocols. Regulates gut and lung inflammation, supports immune balance.
Survodutide
Dual GLP-1/glucagon weight loss peptide from Boehringer Ingelheim. The glucagon component adds liver fat reduction, promising for fatty liver disease alongside obesity.
LL-37
Your body's natural antibiotic peptide. Fights bacteria, viruses, and fungi, breaks up biofilms, and supports wound healing while modulating immune response.
Semaglutide
Active ingredient in Ozempic/Wegovy. Mimics GLP-1 to signal fullness and slow gastric emptying. STEP trials showed 14.9% weight loss at 68 weeks.
Best Synergy Combos
BPC-157 does heavy healing, GHK-Cu improves repair quality with collagen. Construction crew + finishing team.
BPC-157 repairs tissue, TA-1 fine-tunes immune response. Body heals faster without excessive inflammation.
Gut restoration: BPC-157 heals gut lining, KPV is gut-specific anti-inflammatory. Heal damage + stop inflammation.
TA-1 trains T-cells for long-term defense, LL-37 directly kills pathogens on contact.
