Healius Peptides is a research peptide supplier shipping research-grade peptides to laboratories, independent researchers, and contract research organizations worldwide. The catalog covers more than 40 pure peptides for applications in weight loss, muscle, cosmetics, injury repair, cognitive, anti-aging, and sexual health research. Every batch is HPLC-tested and verified by an independent third-party laboratory, then shipped with a batch-specific Certificate of Analysis. Browse the full catalog at all peptides.
Healius supplies lyophilized research peptides packaged in amber glass vials, plus pre-configured peptide blends and multi-vial bundles for researchers running multi-peptide protocols. Every product on the storefront is supplied for in vitro research use only. We do not supply finished pharmaceutical products, drugs, or anything intended for human or veterinary administration.
No. All Healius peptides are designated Research Use Only. They are sold for in vitro laboratory and preclinical research only and are not approved by the FDA, MHRA, TGA, or any other regulatory body for administration to humans or animals. Buyers are responsible for ensuring compliance with the laws and regulations of their jurisdiction. Full terms are on our terms and conditions page.
Every Healius peptide is guaranteed to exceed 99% purity by HPLC. The figure is confirmed by both internal HPLC and mass spectrometry analysis, and by an independent third-party laboratory, before any batch enters saleable inventory. The purity figure for your specific batch is published on the Certificate of Analysis that ships with every order. View the COA for your batch on the lab testing page.
Yes. Healius offers a 60-day money-back guarantee on purity. If a batch is independently retested within 60 days of delivery and the result falls below the 99%+ HPLC purity specification on the Certificate of Analysis, Healius will refund the order in full. Full guarantee terms are on the refund returns page.

Read more on the about us page.
Three things set Healius apart. First, every batch is independently third-party tested at a US-based ISO 17025-accredited laboratory before release, with the external certificate published on the COA. Second, Healius accepts major credit and debit cards (Visa, Mastercard, American Express), providing buyers with card-network consumer protection that most peptide suppliers do not offer. Third, the 60-day money-back guarantee on purity is backed by the published analytical data, not by marketing claims. Compare on the lab testing page.
Yes. Every Healius batch undergoes two rounds of testing before it ships. First, our quality control team runs internal HPLC for purity and mass spectrometry for identity. Second, the same batch is sent to an independent third-party laboratory in the United States for blind verification. Both results are published on the Certificate of Analysis that ships with every order. Read the full program details on lab testing.
The full third-party panel covers seven analytical endpoints: peptide identity by mass spectrometry, peptide purity by reversed-phase HPLC, endotoxin level, heavy metals (arsenic, cadmium, lead, mercury), microbial bioburden, residual solvents (against ICH Q3C limits), and water content by Karl Fischer titration. Every result is recorded on the Certificate of Analysis attached to your batch. View a sample COA at lab testing.
At a US-based independent contract laboratory that holds current ISO/IEC 17025 accreditation for the analytical methods Healius commissions. The lab name and accreditation number are printed on the Certificate of Analysis for each batch.
99% or higher purity by HPLC. The specification is strict: any batch that does not meet 99%+ HPLC purity, fails identity confirmation by mass spectrometry, or fails any other element of the third-party panel is rejected before release. The HPLC purity figure for your specific batch is published on the Certificate of Analysis: view it on the lab testing page.
Use the Certificate of Analysis search on the lab testing page. Enter the lot number printed on your vial label, or search by product name, and the matching COA PDF is available for immediate download. Every COA contains the HPLC chromatogram, mass spectrometry trace, third-party verification certificate, batch date, manufacturing data, and the signature of the releasing analyst.
Yes. Every product page links directly to the most recent batch Certificate of Analysis for that product. You can review the actual HPLC chromatogram and identity confirmation before adding the product to your cart. Older batch COAs are also available on the lab testing page using the COA search.
Any batch that fails any element of the testing panel is rejected and either re-purified or destroyed, depending on the failure mode. A failed batch never enters saleable inventory. The next batch of that peptide is then synthesized and retested before release. This is why a peptide may show a brief out-of-stock window between batches.
Yes. Healius commissions third-party peptide testing only from laboratories that hold current ISO/IEC 17025 accreditation for the relevant analytical methods. The accreditation number for the lab that verified your batch is printed on the Certificate of Analysis. ISO/IEC 17025 is the international standard for the technical competence and impartiality of testing and calibration laboratories.
Healius accepts all major credit and debit cards: Visa, Mastercard, and American Express. This is a deliberate point of difference. Most research peptide suppliers restrict checkout to bank transfer or cryptocurrency, which leaves the buyer with no chargeback rights and no card-network consumer protection. By processing card payments through a fully PCI-compliant payment gateway, Healius gives every buyer the protection of their card issuer if anything goes wrong with an order. We also support Apple Pay and Google Pay, where available at checkout. Bank transfer is available for institutional and bulk orders on request. Email support@healiuspeptides.com to set up.
Yes. Card payments are processed through a PCI DSS-compliant payment gateway with 3D Secure authentication, where supported by your card issuer. Healius does not store full card numbers on our servers. The payment process is fully encrypted in transit (TLS 1.2 or higher), and your card details are tokenized before reaching our system.
Bank transfer is available for institutional and bulk orders on request, but is not offered as a default checkout method. Card payment is the recommended payment route because it gives you card-network chargeback rights and faster refund processing. Cryptocurrency is not currently accepted on the standard storefront.
Browse the all peptides catalog, select your peptide and vial size, add to cart, and proceed through secure card checkout. You will receive an order confirmation email within minutes and a separate dispatch confirmation email with tracking information once your order ships. Orders placed before the daily cutoff are dispatched the same business day.
Pending payment means the order has been placed in our system, but the payment has not yet been authorized. This usually clears within a few minutes. If it does not clear within 24 hours, the order will be canceled automatically, and your card will not be charged. If you see a pending payment for longer than expected, contact support@healiuspeptides.com with your order number.
Processing means your payment has been successfully authorized, and your order is queued for picking, packing, and dispatch from our fulfillment facility. Most orders move from Processing to Shipped within one business day. You will receive a separate dispatch email with tracking information when your order leaves the warehouse.
On hold means the order requires manual review before it can be picked. This is rare and usually occurs during a payment verification check or an address verification step. Failed means the payment did not complete: typically, a card decline, an expired card, or a mismatch between your billing address and the card on file. Failed orders do not result in a charge to your card. Re-attempt the order with corrected details or contact support@healiuspeptides.com for help.

Healius issues refunds back to the original payment method in three situations: a defective or damaged product, a delivery that fails to arrive within the courier window, or an independent re-test that returns a result below the 99%+ HPLC purity specification within 60 days of delivery. Full conditions are on the refund returns page. Refunds are processed within 7 to 14 business days after approval.
No. Healius peptides cannot be returned or exchanged unless the product is faulty, because they are sterile goods, and the chain of custody for a sterile vial is broken once the vial leaves our facility. This is standard policy across the research peptide industry. If your product is faulty, contact support@healiuspeptides.com with your order number and a description of the fault, and we will arrange a refund or replacement under the policy.
If you independently re-test a Healius batch within 60 days of delivery, and the verified analytical result falls below the 99%+ HPLC purity figure published on the Certificate of Analysis, Healius will refund the order in full. The independent re-test must be performed by a competent laboratory using a comparable HPLC method. Submit the alternative analytical data with your order number to support@healiuspeptides.com to initiate the claim. Full conditions are on the refund returns page.
Email support@healiuspeptides.com with your order number, the reason for the refund (defective product, non-delivery, or purity guarantee claim), and supporting evidence (photographs for damaged goods, courier confirmation for non-delivery, alternative analytical data for purity claims). Our customer team will respond within one business day with the next step.
Once a refund is approved, processing takes 7 to 14 business days to appear on your card statement. Card refunds are sent immediately from our payment gateway, but the time taken to appear on your statement depends on your card issuer. Bank transfer refunds for institutional orders typically process within 5 business days.
Photograph the damaged packaging and product before opening any further, then email support@healiuspeptides.com with your order number and the photographs within 48 hours of delivery. For lost orders, contact us once the courier has marked the parcel as undeliverable or once the standard delivery window for your country has elapsed. Healius will arrange a replacement shipment or a full refund.
Stop using the product immediately and email support@healiuspeptides.com with photographs of the vial, label, packing slip, and Certificate of Analysis. We will investigate, replace the affected stock, and trigger a batch review where required. This is treated as a quality incident and is resolved as a top priority.

Lyophilized (freeze-dried) peptides should be stored at minus 20 degrees Celsius or colder, in their original sealed amber glass vial, protected from light and moisture. Under those conditions, lyophilized peptides typically maintain 99%+ HPLC purity for 24 to 48 months. Full storage detail and shelf-life tables are at reconstitution storage.
Once reconstituted with bacteriostatic water, peptide solutions should be refrigerated at 2 to 8 degrees Celsius and used within the shelf life noted on the product page (typically 1 to 8 weeks depending on peptide chemistry). Do not freeze reconstituted solutions unless aliquoted for single-use. Full reconstituted shelf-life tables are at reconstitution storage.
Inject the calculated volume of bacteriostatic water slowly down the inside wall of the vial so the stream does not strike the lyophilized pellet. Swirl gently for 30 to 60 seconds. Do not shake. Most standard peptides should fully dissolve within this window. For exact bacteriostatic water volumes, use the calculator. For the full step-by-step protocol, see reconstitution storage.
Bacteriostatic water is sterile water with 0.9% benzyl alcohol added as a preservative. Benzyl alcohol inhibits bacterial growth in a multi-dose vial, allowing the reconstituted solution to be used within its refrigerated shelf life. Bacteriostatic water is the default solvent for most research peptides.
Standard hydrophilic peptides reconstituted in bacteriostatic water typically remain stable for 4 to 8 weeks at 2 to 8 degrees Celsius. Peptides with free cysteine or methionine residues typically hold 1 to 2 weeks. Hydrophobic peptides reconstituted in acetic acid typically remain stable for 2 to 4 weeks. Specific shelf life by peptide class is on reconstitution storage.
Freezing slows degradation, but each freeze-thaw cycle costs 1-5% of purity, depending on peptide chemistry. Best practice is to aliquot the reconstituted vial into single-use volumes before freezing, so each aliquot is thawed once. Avoid freeze-thawing the same aliquot twice. Detailed aliquot strategy is at reconstitution storage.
A 1 mL U-100 insulin syringe is the standard choice for most research draws. For very small draws (below 5 IU on the U-100 scale), a 0.3 mL or 0.5 mL syringe gives finer resolution. The calculator returns the exact draw volume in both mL and IU for any vial size and target dose.
Avoid four common mistakes: vigorous shaking during reconstitution, injecting bacteriostatic water directly onto the lyophilized pellet, storing reconstituted solution at ambient temperature, and freeze-thawing the same aliquot more than once. The full list of mistakes to avoid is on reconstitution storage.
