The CorTheory Difference
Research Compounds
High-purity sequenced peptides and lyophilised coenzymes synthesized for exacting laboratory protocols and molecular analysis.
Concentration Verified
Every CorTheory compound is independently assayed for active concentration before release. HPLC-based potency analysis confirms each vial contains the stated quantity within ±2% variance — ensuring reliable and reproducible research outcomes.
Shop Now →99%+ Grade Standard
Purity is measured via reverse-phase HPLC at accredited laboratories. Impurity profiling identifies and quantifies any off-target peaks. Only batches reaching ≥99% purity are dispatched — no exceptions.
Shop Now →Long-Term Integrity
Lyophilisation is performed under controlled conditions to maximise shelf-life. Stability studies confirm degradation rates well within acceptable limits. Properly stored peptides retain potency for 24+ months at -20°C.
Shop Now →Residual Solvent Screening
All batches are screened for residual solvents, heavy metals, and microbial contamination per international pharmacopoeial standards. Safety testing is performed at independent, accredited third-party facilities prior to release.
Shop Now →Batch-to-Batch Reliability
CorTheory maintains rigorous batch records and inter-batch comparison data. The compound you receive today matches the specification of every prior batch — same sequence, same purity, same result.

All CorTheory peptides are independently tested to 99%+ purity using HPLC analysis and mass spectrometry. Every batch is verified by accredited laboratories before dispatch.
A CoA confirms the identity, purity, and concentration of your compound. Look for the HPLC chromatogram, purity percentage, and molecular weight confirmation. All CorTheory orders include a CoA.
We recommend bacteriostatic water for most peptides. Add solvent slowly along the vial side and allow to dissolve without agitation. Store reconstituted peptides at 4°C.
Store lyophilised peptides at -20°C for long-term stability. Once reconstituted, refrigerate at 4°C and use within 28 days. Keep away from light and humidity.
Premium research-grade peptides engineered for precision and molecular stability. Tested and verified for absolute purity.
