Star Rating: 4.0 / 5.0
Product Quality
AminoVault's 27-listing catalog demonstrates deliberate specialty compound positioning within its core research mandate:
- •Thymalin (Thymic Bioregulator): This is one of the most distinctive catalog entries across all supplier reviews in this batch. Thymalin is a calf-thymus bioregulator peptide studied for its immunomodulatory effects, thymus-mediated immune function regulation, and anti-aging properties in longitudinal animal research models. It is part of the Khavinson peptide research program — the same research tradition responsible for Epithalon — and has been studied in combination with Epithalon for synergistic effects on immune regulation, antioxidant activity, and longevity biomarkers. AminoVault offers both the Thymalin standalone compound (THYMALIN 10mg in 10-vial packs) and a Thymalin + Epithalon Blend — providing both single-compound and combination experimental options for immunogerontology research.
- •LY3437943 (Novel Triple GLP Agonist): LY3437943 is a GLP-1R/GIPR/GCGR triple agonist distinct from Retatrutide in molecular structure, studied in advanced metabolic biology research as an alternative triple-receptor pharmacology tool. Researchers studying convergent GLP/GIP/glucagon signaling and its effects on energy expenditure, hepatic lipid metabolism, and adipose tissue biology will find LY3437943 a valuable comparative research tool alongside standard Retatrutide.
- •SS-31 (Elamipretide): SS-31 is a mitochondria-targeting tetrapeptide (D-Arg-dimethylTyr-Lys-Phe-NH2) that selectively associates with the inner mitochondrial membrane through cardiolipin binding. It is studied in cardioprotection research, mitochondrial membrane potential stabilization, reactive oxygen species reduction, and ATP synthesis support. Its inclusion in the AminoVault catalog — alongside other mitochondrial biology tools like MOTS-c — reinforces the company's positioning toward cardiovascular and bioenergetics research.
- •Growth Hormone-Axis Coverage: The GH-axis segment includes CJC-1295 without DAC (Modified GRF 1-29, 5mg) for pulsatile GHRH signaling studies, CJC-No DAC/Ipamorelin Blend (5mg/5mg) for GHRH/GHRP combination research, the FIT Stack (a branded CJC-1295 + Ipamorelin combination), Sermorelin (GHRH 1-29 analog), and Tesamorelin (44-amino acid GHRH analog for visceral adiposity research). The range covers foundational to advanced GH-axis research designs.
- •Tissue Healing and Healing Combination Formats: BPC-157/TB-500 combination formulations, BPC-157/TB-500/KPV/GHK-Cu four-compound KLOW Stack, and standalone KPV are all available. GHK-Cu (120mg, the distinctive blue/purple packaging format) provides bulk copper peptide for wound healing and collagen synthesis research. Thymosin Alpha-1 (10mg) covers immune regulation and thymic biology — a thematically consistent companion to the Thymalin entries.
- •Metabolic and Immune Compounds: Glucagon-Like Peptide-1 (7-36, 10mg) and Glucagon-Like Peptide-2 (1-33, 10mg) are listed as discrete GLP compound research tools for researchers studying specific peptide fragments. Semax covers neuroprotective and cognitive biology. MOTS-c supports mitochondrial biology and metabolic adaptation research. Melanotan I supports pigmentation and photoprotection biology.
- •Support Compounds: NAD+ (1,000mg) covers nicotinamide coenzyme biology. L-Glutathione supports antioxidant and redox biology research. Vitamin B12 Cyanocobalamin injectable supports cofactor biology research. Shipping protection is offered as an optional purchase add-on.
Testing Standards
AminoVault 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 HPLC purity and mass spectrometry identity documentation for any compound before use in experimental protocols. The specialty compound nature of Thymalin and LY3437943 makes independent identity verification particularly important, as these are less widely characterized in the commercial research market and analytical reference standards may require additional sourcing.
Pricing & Selection
AminoVault accepts Zelle and Cash App — payment methods that differ from the credit card and cryptocurrency options common among comparable vendors. This may represent a practical convenience for researchers who prefer direct bank transfer payment methods, though researchers should factor payment method security into their overall procurement evaluation.
The 27-listing footprint provides comprehensive coverage across GH-axis, thymic biology, metabolic pharmacology, and healing compound categories. Exact per-mg pricing for specific compounds is best verified directly through the supplier's website, as current promotional pricing may differ from historical data.
The dual-entry approach for Thymalin (standalone and blend) and LY3437943's presence alongside Glucagon-Like Peptide-1/GLP-2 fragments provide genuinely differentiated options for researchers requiring specialty compounds or multi-receptor agonism pharmacology tools.
Customer Experience
AminoVault's primary procurement resource is their website at aminovault.com. Payment via Zelle and Cash App may offer faster transaction processing than bank wire alternatives for domestic researchers, though researchers should confirm current payment policies directly with the supplier.
The catalog's specialty compound depth — particularly Thymalin, Thymalin + Epithalon Blend, and LY3437943 — provides meaningful research differentiation for immunogerontology and frontier metabolic pharmacology researchers who cannot readily source these compounds from generic catalog vendors.

Research Context: AminoVault's Specialty Entries
Thymalin and Thymalin + Epithalon Blend: Thymalin is a polypeptide bioregulator extract derived from thymic gland tissue, developed at the Saint Petersburg Institute of Bioregulation and Gerontology (Vladimir Khavinson's program). It stimulates thymosin production and T-cell maturation, making it relevant to immunogerontology research — the study of immune decline with aging. Thymalin is distinct from synthetic thymic peptides like Thymosin Alpha-1 (Ta1) and Thymulin; it represents the full peptide fraction of thymic extract rather than a single characterized sequence. The Thymalin + Epithalon Blend combines thymic immune restoration biology with pineal/telomerase research biology (Epithalon = Ala-Glu-Asp-Gly, the synthetic pineal tetrapeptide that activates telomerase in somatic cells). This combination is of interest in comprehensive aging biology research programs. See: Epitalon Research Profile | Thymulin Research Profile
LY3437943 vs Retatrutide — are they the same compound? Many research suppliers list Retatrutide under its Eli Lilly clinical designation (LY3437943) rather than the INN name "Retatrutide." Chemically, they are identical: LY3437943 IS Retatrutide, the GLP-1R/GIPR/GCGR triple agonist. AminoVault's catalog listing it as "LY3437943" rather than Retatrutide is simply a naming preference — the clinical API name rather than the WHO-assigned INN. This naming distinction is relevant for researchers searching for purity documentation: COAs may reference either name, and both should be mapped to the same sequence for identity verification.

Frequently Asked Questions: AminoVault
Q: What is Thymalin and how does it differ from other thymic peptides like Thymosin Alpha-1 or Thymulin?
A: Thymalin is a polypeptide bioregulator fraction extracted from animal thymus tissue — it contains a mixture of thymic peptides rather than a single characterized sequence. In contrast, Thymosin Alpha-1 (Ta1, Zadaxin) is a specific 28-amino-acid synthetic peptide (Ac-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-OH) derived from the naturally occurring Thymosin fraction V; and Thymulin (zinc-dependent nonapeptide, FTS) is a single-sequence thymic hormone with a known structure and zinc-binding mechanism. Thymalin's biological activity stems from its peptide mixture rather than a single molecular target, which makes it more complex to characterize analytically. Researchers studying thymic biology who need defined pharmacology should use Ta1 or Thymulin; researchers studying the integrative bioregulatory effects of thymic extracts can use Thymalin.
Q: Why is AminoVault listing Retatrutide as "LY3437943" instead of its INN name?
A: LY3437943 is Eli Lilly's internal development code for Retatrutide — assigned before the WHO issued the INN "retatrutide." Some suppliers prefer the development code because it is unambiguous (it references Lilly's proprietary compound specifically), while others use the INN. Both refer to the same triple GLP-1R/GIPR/GCGR agonist. When evaluating COAs for this compound, confirm the molecular weight (4813.5 Da for the active form) and sequence matches regardless of which name the COA uses. Researchers who cite this compound in experimental records should use the INN "retatrutide" for publications to align with current nomenclature.
Q: What is the FIT Stack at AminoVault, and what does it cover?
A: AminoVault's FIT Stack is a branded combination research package. Without the full specification, the most common "FIT"-branded research stacks in the 2026 market combine a GH secretagogue (typically CJC-1295 or Sermorelin) with a healing compound (BPC-157 or TB-500) and a metabolic or fat-mobilization compound (AOD-9604, 5-Amino-1MQ, or similar). The branded stack format reduces individual compound selection overhead for researchers running a predefined protocol. Researchers should confirm the exact components, quantities, and compound identities in the FIT Stack before incorporating it into a defined mechanistic study — the branded format may not allow independent component control.
Q: Does AminoVault accept credit card payments?
A: AminoVault accepts Zelle and Cash App as their noted payment methods. These are peer-to-peer transfer services that offer limited buyer protection compared to credit card or payment processor transactions. Researchers making a first-order from an unverified supplier through peer-to-peer payment should weigh this against the added due diligence requirements of limited chargeback options if the order is not fulfilled. For first-time orders, starting with a small single-compound test purchase before committing to a multi-compound protocol order is a prudent approach.
Q: How does AminoVault's 27-listing catalog compare to the broader supplier market?
A: At 27 listings, AminoVault is on the narrower end of the suppliers reviewed — for context, other suppliers in this batch range from 20 (BulkGLP) to 118 (Simple Peptide) listings. The narrow count is not inherently a weakness; specialty suppliers often achieve better quality control and supplier consistency across a focused catalog than broad-spectrum vendors managing hundreds of SKUs. AminoVault's specialty depth is in immunogerontology (Thymalin, Thymalin + Epithalon), mitochondrial biology (SS-31), and frontier metabolic research (LY3437943/Retatrutide, Thymosin Alpha-1). Researchers who need these specific compound classes and are willing to use a second supplier for standard catalog compounds like BPC-157 or Semaglutide can benefit from this specialty depth.
Q: Is AminoVault verified on Peptides.SO?
A: AminoVault holds no verified badge on Peptides.SO and has no accumulated platform rating data. Its location is listed as "Unknown." Researchers conducting due diligence should request batch-specific COA documentation (HPLC purity, mass spectrometry, preferably with endotoxin) directly from AminoVault, particularly for the specialty compounds (Thymalin, LY3437943) where fewer independent reference standards exist compared to well-characterized compounds like BPC-157 or Semaglutide.
