This Alpha Peptides review covers the company's full research catalog, specialty compound positioning, documented pricing, and overall supplier profile for 2026 as listed on Peptides.SO.
Overview
Alpha Peptides is a U.S.-based research compound supplier with 27 active listings on Peptides.SO. The catalog spans GLP receptor agonist compounds, growth hormone-axis peptides, tissue healing and recovery agents, cosmetic-science peptides, and cardiovascular/mitochondrial research compounds.
What distinguishes Alpha Peptides from many mid-market vendors is the combination of competitive per-mg pricing alongside two genuinely specialized catalog entries: SS-31 (Elamipretide) and TB-500 Fragment 17-23. These higher-specification compounds indicate positioning toward specialized cardiovascular biology and targeted healing research audiences beyond the standard BPC-157/TB-500 commodity market. The company's website is alpha-peptides.com.
Star Rating: 4.0 / 5.0
Product Quality
Alpha Peptides' 27-listing catalog is defined by both mainstream compound breadth and specialty depth:
- •SS-31 (Elamipretide): This is a high-value specialty entry and one of the most research-differentiated compounds in the Alpha Peptides catalog. SS-31 (D-Arg-dimethylTyr-Lys-Phe-NH2) is a cell-permeable tetrapeptide that selectively targets the inner mitochondrial membrane through high-affinity cardiolipin binding. It has been extensively studied in cardioprotective research — including cardiac ischemia/reperfusion injury models, heart failure biology, mitochondrial membrane potential stabilization, reactive oxygen species reduction, and ATP synthesis enhancement in cardiac and skeletal muscle research models. SS-31's presence in the Alpha Peptides catalog signals differentiated positioning toward cardiovascular biology and bioenergetics research audiences who require this specialized compound.
- •TB-500 Fragment 17-23 (10mg): This is the active actin-binding fragment of Thymosin Beta-4, rather than full-length TB-500. TB-500 Fragment 17-23 (LKKTETQ) has been studied for its specific effects on cell motility promotion, wound healing stimulation, and anti-inflammatory signaling — isolating the specific mechanistic effects of the actin-binding domain without the full-length peptide's additional activity. Researchers studying the mechanistic underpinnings of TB-500's activity in isolation from its full sequence will find this a valuable specialty tool.
- •GLP Receptor Research Compounds: The GLP segment covers the full contemporary triad. GLP1 (S, 30mg) provides Semaglutide for GLP-1 receptor agonism research in glucose metabolism and adipose tissue biology. GLP-2 (T) covers Tirzepatide for dual GLP-1R/GIPR agonism. GLP3 (R) provides Retatrutide for triple GLP-1R/GIPR/GCGR receptor pharmacology. Cagrilintide (10mg) extends the catalog into amylin receptor biology relevant to amylin/GLP-1 co-agonism research.
- •CJC-1295 with DAC: The inclusion of the DAC-modified CJC-1295 (in addition to the standard No-DAC version) signals toward researchers specifically studying continuous versus pulsatile GH secretion patterns. CJC-1295 with DAC uses the drug affinity complex modification to extend plasma half-life significantly beyond the No-DAC format, providing a distinct research tool for chronic GH secretion model studies.
- •KLOW Blend (BPC-157/TB-500/KPV/GHK-Cu, 80mg): This four-compound healing combination blend provides synergistic tissue healing biology coverage in a single formulation — relevant to researchers studying multi-pathway healing mechanisms.
- •Additional Specialty Compounds: Melanotan I covers photoprotection and pigmentation biology. PT-141 covers melanocortin receptor pharmacology. DSIP (5mg) addresses sleep biology and opioid receptor research. AOD-9604 (Growth Hormone Fragment 176-191) covers lipolysis and body composition biology. Beauty Blend (GHK-Cu/KPV) provides cosmetic peptide combination research coverage. Selank and Semax address anxiolytic and neuroprotective research. MOTS-c supports mitochondrial biology. Bacteriostatic water (Hospira 30mL) is listed as a reconstitution accessory.
Testing Standards
Alpha Peptides does not currently display third-party certificates of analysis or verification badges on its Peptides.SO profile. The platform testing score is 0.
Researchers should engage the supplier directly to request lot-specific CoA documentation — HPLC purity data and mass spectrometry identity confirmation — before any experimental use. For specialty compounds like SS-31 and TB-500 Fragment 17-23, independent identity verification is particularly important as analytical reference standards for these compounds may require additional sourcing steps.
