What to take with your peptides.
Every entry below pairs with a specific peptide protocol for a documented mechanistic reason. Deficiencies your peptide creates. Side effects you can pre-empt. Synergies that aren't optional if you want full results. Not a generic supplement catalog.
Thiamine (Vitamin B1)
GLP-1 users frequently run B1-deficient because the appetite drop kills food intake before nutrient targets are met.
Magnesium (Glycinate)
Electrolyte that drops with GLP-1 GI side effects and high-dose injection cycles.
Potassium
Primary electrolyte lost during GLP-1 vomiting/diarrhea, most underrated supplement for this class.
Psyllium Husk Fiber
GI normalizer for GLP-1 users, handles constipation and stabilizes blood sugar.
Electrolyte Powder (LMNT-style)
Single-stick fix for sodium/potassium/magnesium loss during early-cycle GLP-1 fatigue.
Creatine Monohydrate
Muscle-preservation insurance during GLP-1-driven weight loss.
TUDCA (Tauroursodeoxycholic Acid)
Liver and bile-flow support, relevant if stacking peptides with anything orally hepatotoxic.
Vitamin D3 + K2
Baseline hormone-axis support that becomes more important on GH-secretagogue stacks.
Omega-3 (EPA/DHA)
Background anti-inflammatory that pairs with healing peptides and supports joint outcomes.
Continuous Glucose Monitor (CGM)
Two-week data on how YOUR glucose responds to a peptide protocol. Most underrated tool in the space.
