Questions,
clearly answered.

Yes. Research peptides are legal to purchase, possess, and use for legitimate scientific and laboratory research purposes in the United States. They are sold as research chemicals, not as drugs, supplements, or food products. Purchasers are responsible for ensuring compliance with all applicable local, state, and federal regulations.

All products sold by Solira Lab are classified as research-grade chemicals. They have not been evaluated or approved by the FDA for human use. The “Not for Human Consumption” designation indicates these products are intended exclusively for in vitro laboratory research and are not formulated, tested, or approved for diagnostic or therapeutic use in humans or animals.

Research peptides are sold in milligram quantities (typically 5-10mg). This is a very small amount of material that may appear as a thin film or small pellet at the bottom of the vial. We do not add fillers or bulking agents. The quantity stated on the label is the actual amount of active compound in the vial, verified by our testing process.

Yes. Research peptides sold for in-vitro laboratory use are not regulated as prescription drugs in the United States. They are classified as research chemicals and do not require a prescription. Solira Lab supplies these compounds exclusively for laboratory research conducted by qualified researchers, not for human or animal use.

Solira Lab does not require purchasers to submit a research license at checkout, but by purchasing you confirm that the compounds will be used exclusively for laboratory research conducted by qualified researchers in compliance with applicable institutional and federal guidelines. Researchers operating within institutions should consult their institutional review process for research-material acquisition.

GLP-1 (glucagon-like peptide-1) research peptides are synthetic compounds studied as agonists of the GLP-1 receptor — a receptor on pituitary and metabolic cells central to incretin and metabolic-pathway research. Solira Lab supplies coded variants (GLP-1S, GLP-2T, GLP-3R) for laboratory research, characterized by their receptor-agonism profile rather than by drug brand names. These compounds are studied in cultured cell and rodent in-vivo models for receptor-pathway research and are not approved for human use.

Yes. Every batch undergoes independent third-party testing. Lot-specific COAs are available on individual product pages when available, or upon request by contacting our team. Our COAs include HPLC purity data and mass spectrometry identity confirmation. See our full testing process for details.

Lyophilized (freeze-dried) peptides should be stored sealed, dry, and protected from light. For long-term storage, −20°C is recommended. For short-term storage, 2-8°C is acceptable. Once reconstituted using sterile technique, most peptide solutions are stable for up to 30 days when refrigerated at 2-8°C. All handling should follow standard laboratory protocols. For comprehensive guidance see our storage guide.

BPC-157 is a synthetic 15-amino-acid pentadecapeptide studied in connective tissue and gastric mucosa research. TB-500 is a substantially larger 43-amino-acid-class fragment of Thymosin Beta-4, studied in cytoskeletal and cell-migration research. They are structurally distinct compounds answering different research questions, though they appear together in connective tissue research literature. See the full comparison at /research/bpc-157-vs-tb-500/.

Standard reconstitution uses bacteriostatic water (water with 0.9% benzyl alcohol as preservative) or sterile saline. The choice depends on the assay system and downstream methodology in your specific research protocol. Add the solvent slowly along the inside of the vial wall to minimize foaming; do not shake. Allow the lyophilized powder to dissolve fully before use. See the full storage and reconstitution guide.

Lyophilized research peptides stored at −20°C in a sealed dark container retain documented stability for 24 months or longer per manufacturer guidance. Once reconstituted in solution, stability is significantly reduced and depends on the specific compound, buffer system, and storage temperature. Aliquot reconstituted material before freezing to avoid repeated freeze-thaw cycles.

You can add any of our 10-pack products directly to your cart from the product page or the Wholesale page. 10-packs offer approximately 20% savings over single-vial pricing. For custom quantities beyond 10 packs, please contact us directly.

At this time, Solira Lab ships to US domestic addresses only. All orders over $200 qualify for free shipping. Orders placed before 3pm EST ship the same business day.

We accept credit and debit cards through our secure payment gateway. Cryptocurrency payments are also accepted. All transactions are processed securely and your payment information is never stored on our servers.

Due to the nature of research chemicals and the need to maintain supply chain integrity, we do not accept returns on peptide products. If you receive a damaged or incorrect order, please contact us within 48 hours with photographs. We will issue a replacement or store credit at our discretion.

Solira Lab is a US-based direct-source supplier of research-grade peptides, fulfilling all orders from a US fulfillment center to US domestic addresses. Researchers can browse the full catalog at /shop/ — 37 single-vial compounds plus wholesale 10-packs and pre-formulated research blends. For criteria on evaluating any peptide supplier, see our supplier-evaluation reference.

Solira Lab supplies research-grade peptides verified by independent third-party HPLC and mass spectrometry analysis on every manufactured lot. Every order ships with a lot-specific Certificate of Analysis linking the physical vial to its test record. Solira does not self-certify purity. Our full testing process page documents the workflow, and the criteria for evaluating any peptide supplier are documented in our supplier-evaluation reference.

Solira Lab works through direct manufacturing partnerships to reduce reseller markup. Most peptide vendors operate as intermediaries — they buy from a manufacturer at one price and resell at a 2–5× markup. Direct-source means the supplier has a direct relationship with the manufacturer, eliminating the markup layer. Solira passes the resulting savings to researchers while maintaining the same third-party testing and COA standards required for research-grade purity.

Orders placed before 3 PM Eastern Time ship the same business day from our US fulfillment center. Standard ground shipping arrives in 3–7 business days; Priority arrives in 2–3 business days; 2 Day Express arrives in 2 business days. All orders over $200 qualify for free shipping. Solira ships to US domestic addresses only.
