Research-grade peptides are short chains of amino acids synthesized for laboratory and investigational use. They are produced to strict purity standards — at Eterna, every lot is independently verified to 99%+ purity via LC-MS (Liquid Chromatography–Mass Spectrometry). Our peptides are manufactured in US cGMP-certified facilities under the same standards required for FDA-regulated pharmaceuticals, making them among the highest-quality compounds available to practitioners and researchers.

All Eterna Peptides are manufactured exclusively in the United States in facilities operating under current Good Manufacturing Practice (cGMP) — the gold standard applied to FDA-regulated pharmaceutical products. Every vial carries a lot number, batch ID, and expiration date so you can trace exactly what you're receiving. We never use overseas or unverified suppliers.

Eterna carries over 97 research compounds across eight categories: Fat Loss (e.g., AOD-9604, Cagrilintide), Strength, Longevity (e.g., Epithalon, BPC-157), Metabolism, Cognitive (e.g., Dihexa, Cerebrolysin, Cerebra X), Sexual Health, Immunity, and Healing. Popular compounds include BPC-157, CJC-1295/Ipamorelin, TB-500, DSIP, Aicar, and many more. Browse the full catalog at our Shop All page.

Every lot undergoes independent third-party LC-MS (Liquid Chromatography–Mass Spectrometry) analysis — not self-reported testing. LC-MS is the most rigorous method for verifying peptide identity, sequence accuracy, and purity. Results are documented in a Certificate of Analysis (COA) that ships with every order. You can also view lot-specific COAs on our Certificates of Analysis page.

Yes. A lot-specific Certificate of Analysis (COA) ships with every single order. Each COA includes the peptide name, lot number, batch ID, purity percentage (verified at 99%+), test date, and the methodology used (LC-MS). This provides full lot traceability and is essential for practitioners maintaining research records. COAs are also publicly accessible on our website by lot number.

Eterna peptides are available in multiple forms depending on the compound:

• Lyophilized (freeze-dried) powder — the most stable form for long-term storage and research use
• Reconstituted liquid — pre-reconstituted for immediate use (e.g., AOD-9604 Reconstituted)
• Capsules — oral capsule form for select peptides (e.g., BPC-157 Capsules, Dihexa Capsules, 5-Amino-1MQ Capsules)
• Facial serums — topical peptide formulations

We also carry Bacteriostatic Water for reconstitution.

Orders placed before 12:00 PM PST Monday–Wednesday ship same day. We dispatch lyophilized peptides with ice packs and use a Monday–Wednesday shipping window to protect cold-chain integrity and prevent weekend delays in transit. Standard domestic delivery takes up to 7 business days from shipment. Expedited and same-day courier options are available for Southern California customers.

Yes. Free standard shipping is available on all US orders over $300. For smaller orders, flat-rate shipping fees apply at checkout. Professional and Strategic membership plan holders enjoy additional shipping benefits including preferred shipping rates. See our full Shipping Policy for details.

At this time, Eterna Peptides ships within the United States only. We do not currently offer international shipping. All orders must be placed with a valid US shipping address. If you are a US-based practitioner with research programs that require domestic fulfillment, contact us at support@eternapeptides.com or call +1 (714) 367-6327.

Yes — for customers in Southern California (including San Diego, Orange County, Los Angeles, Riverside, and San Bernardino), we offer same-day or next-day courier delivery depending on order size and courier fee. To arrange local courier delivery, contact our team directly at support@eternapeptides.com or +1 (714) 367-6327 (Monday–Saturday, 8:00 AM–5:00 PM PST).

Once your order ships, you will receive a confirmation email with a tracking number. You can also use our dedicated Track My Order page at any time to check your shipment status. If you have questions about your order or tracking, contact support at support@eternapeptides.com.

No membership is required to place an order. Eterna Peptides is open to all qualified practitioners and researchers. However, membership plans unlock benefits such as preferred pricing, a referral program, bulk pricing, priority access to new compounds, and a dedicated advisor. See our Membership page for plan details.

Eterna Peptides are sold as research compounds for investigational and laboratory use. They are trusted by board-certified physicians and practitioners for research programs. All products are manufactured to the highest purity and quality standards. Usage decisions should be made in consultation with a licensed medical professional in accordance with applicable laws and regulations in your jurisdiction.

Proper storage is critical for peptide stability:

• Lyophilized peptides: Store at −20°C (freezer) for long-term storage; stable at 4°C (refrigerator) for shorter periods. Keep away from light and moisture.
• Reconstituted peptides: Refrigerate at 2–8°C and use within the time frame specified on the label. Do not freeze reconstituted solutions.
• Capsules: Store in a cool, dry place away from direct sunlight at room temperature unless otherwise indicated.

Every vial includes a batch ID and expiration date. Eterna ships all products with ice packs to preserve cold-chain integrity during transit.

Bacteriostatic water (BW) is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. It is used to reconstitute (dissolve) lyophilized peptide powders prior to use. Eterna offers bacteriostatic water in multiple sizes starting at $12.50. Using proper BW ensures your peptides remain stable and uncontaminated once reconstituted.

Yes. Independent third-party testing via LC-MS verifies both purity and identity of every lot. Our US cGMP manufacturing environment also enforces strict protocols for sterility, contamination control, and quality assurance throughout the production process. Unlike many suppliers that rely on self-reported data, Eterna's testing is independently confirmed — results are documented in lot-specific Certificates of Analysis.

Eterna offers three tiered membership plans designed for practitioners at every stage:

A Certificate of Analysis (COA) is a document issued by an independent testing laboratory confirming a product's identity, purity, and composition. For peptides, the COA verifies that the compound is what it claims to be and meets stated purity thresholds (99%+ at Eterna). It is essential for practitioner due diligence, patient safety, and research integrity. A COA ships with every Eterna order, and lot-specific COAs are publicly available on our website.

COAs are provided in two ways: (1) a printed or digital COA ships with every order, and (2) you can look up any lot by visiting our Certificates of Analysis page and entering the lot number printed on your vial. This gives you 24/7 access to documentation — ideal for maintaining practitioner records or verifying product details before administration.

LC-MS (Liquid Chromatography–Mass Spectrometry) combines separation science with molecular identification to precisely characterize compounds. For peptides, it confirms the amino acid sequence, molecular weight, and eliminates impurities with unmatched sensitivity. It is considered the most reliable analytical method in peptide quality assurance — far superior to HPLC-only testing. At Eterna, every lot is verified via LC-MS by an independent third-party laboratory, not internally.
