FOUNDATIONS
What Are Research Peptides?
Research peptides are synthetic amino acid chains produced for use in controlled laboratory settings. They are studied for their interactions with specific biological receptors, enzymes, and signaling pathways — providing researchers with precise, reproducible tools for investigating mechanisms that would otherwise require endogenous hormones or complex biological extracts.
The burden of quality assurance falls entirely on the supplier. The critical variables to verify before ordering: purity (HPLC chromatography), identity (mass spectrometry), and documentation (a batch-specific Certificate of Analysis from an independent third-party laboratory).
Alpha Peps supplies all peptides at 99%+ HPLC-verified purity with a third-party COA included with every order.
Purity Testing
HPLC Analysis
High-Performance Liquid Chromatography separates and quantifies peptide components. A result of 99%+ means less than 1% of the sample is anything other than the target compound — the baseline minimum for research-grade material.
Identity Confirmation
Mass Spectrometry
Mass spec confirms the molecular weight matches the theoretical weight of the target peptide sequence. HPLC tells you how pure it is — mass spec tells you what it actually is. Both are required for a complete quality picture.
Documentation
Certificate of Analysis (COA)
A batch-specific COA from an independent third-party laboratory documents purity, mass spec confirmation, and testing date for your specific lot. Generic or undated COAs are not acceptable for serious research.
Storage Format
Lyophilized Powder
All Alpha Peps peptides ship as lyophilized (freeze-dried) powder — stable at room temperature for transit, maximum shelf life stored at -20°C. Reconstitution with bacteriostatic water required prior to use.
RESEARCH CLUSTER 01
Growth Hormone Axis & Metabolic Research
Peptides working on the hypothalamic-pituitary GH axis — GHRH receptor agonists (Sermorelin, CJC-1295, Tesamorelin), ghrelin receptor agonists (Ipamorelin), and downstream metabolic modulators (AOD-9604, GLP-3). Several have completed human clinical trials, making this cluster the most evidentially grounded in the catalog.
Sermorelin · GHRH 1-29
The GHRH Analog With an FDA History
FDA-approved pharmaceutical history. Most human clinical data of any GHRH analog in the research catalog.
Read Overview →CJC-1295 / Ipamorelin · Dual Pathway
The Dual-Pathway GH Research Stack
CJC-1295 activates the GHRH receptor. Ipamorelin suppresses somatostatin. Together they produce a larger GH pulse than either alone.

Regulatory Status: What Researchers Need to Know
The regulatory landscape shifted significantly in 2025 when the FDA moved several compounds — including BPC-157 and CJC-1295/Ipamorelin — to Category 2 bulk drug substance status, restricting compounded pharmaceutical use. Regardless of compounding status, these compounds remain available as research chemicals for non-clinical laboratory use.
| Compound | Research Status | Regulatory History |
|---|---|---|
| Sermorelin | ● Available | FDA-approved (Geref/Gerel), discontinued 2008. Largest human data set of any GHRH analog. |
| Tesamorelin | ● Available | Currently FDA-approved (Egrifta). Research chemical use is separate and unrestricted. |
| AOD-9604 | ● Available | Phase IIb discontinued 2007. FDA GRAS status for oral use. Research use unrestricted. |
| BPC-157 | ● Available | FDA Category 2 (2025) — restricts compounding only. Research chemical status unaffected. |
| CJC-1295 / Ipamorelin | ● Available | Category 2 bulk drug substance. Research chemical status unaffected. |
| TB-500 / GHK-Cu / DSIP / GLP-3 | ● Available | No specific FDA regulatory action. Available without compounding restriction. |
