Onyx Peptides: Frequently Asked Questions (FAQ)

Welcome to the Onyx Peptides FAQ Knowledge Base. This guide covers questions regarding product purity, ordering procedures, shipping policies, peptide storage, related research compounds, and current promotional offers.

Category 1: About Onyx Peptides & Purity Standards

Q1: What is Onyx Peptides?

Onyx Peptides is a domestic provider of high-purity research peptides and biochemical compounds dedicated to supporting laboratory research and clinical development.

Q2: Are Onyx Peptides products intended for human consumption?

No. All products sold by Onyx Peptides are strictly for in vitro research, educational, and laboratory purposes only. They are not intended for human consumption, clinical diagnostic use, or veterinary applications.

Q3: How does Onyx Peptides verify product purity?

Every batch of peptides undergoes independent, third-party laboratory testing using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to guarantee purity levels exceeding 98% or 99%.

Q4: Can I request Certificates of Analysis (COAs) for my batch?

Yes. COAs are accessible directly on our website or can be provided by customer support for every product lot.

Q5: What forms do your research peptides come in?

Our peptides are supplied in lyophilized (freeze-dried) powder form inside sealed glass vials to preserve stability during shipping and long-term storage.

Q6: Where are Onyx Peptides processed and distributed?

Our operational headquarters and distribution centers are based domestically in the United States, allowing for rapid fulfillment and reliable quality control.

Category 2: Ordering, Payment & Domestic Shipping

Q7: How long does domestic shipping take?

Orders typically ship within 24 to 48 hours. Standard ground delivery takes 2–4 business days, with expedited shipping options available at checkout.

Q8: Does Onyx Peptides provide order tracking?

Yes. Once an order is processed, an automated email containing a tracking number is sent to monitor shipment status in real time.

Q9: What payment methods are accepted?

We accept major credit cards, debit cards, bank transfers (ACH/Wire), and select cryptocurrency options for fast, secure checkout.

Q10: What is your order cancellation policy?

Orders can be canceled or updated prior to processing and shipment dispatch by contacting customer support immediately.

Q11: What happens if my package is lost or damaged in transit?

If your shipment is damaged or lost in transit, contact our support team with your order number and photos of damaged packaging to arrange a prompt reshipment.

Q12: Do you ship internationally?

Check our Shipping Policy page at checkout for the current list of approved international shipping destinations and regulatory compliance details.

Category 3: Storage, Handling & Reconstitution

Q13: How should un-reconstituted (lyophilized) peptides be stored?

Store lyophilized peptide vials in a dry, dark place at temperatures between -20°C and 4°C. At freeze temperatures (-20°C), un-reconstituted vials remain stable for up to 24 months.

Q14: What is the recommended liquid for peptide reconstitution?

Sterile Bacteriostatic Water (BAC Water) containing 0.9% benzyl alcohol is recommended for reconstitution to prevent bacterial growth and maintain stability.

Q15: How should reconstituted peptide solutions be stored?

Once reconstituted, store liquid vials in a dedicated laboratory refrigerator at 2°C to 8°C (36°F to 46°F) and use within 30 days.

Q16: Can reconstituted peptides be frozen?

Freezing reconstituted liquid solutions is generally not recommended, as repeated freeze-thaw cycles degrade the peptide chain structure.

Q17: Why is it important to protect peptides from light?

Direct exposure to ultraviolet (UV) light and room lighting can accelerate oxidation and enzymatic degradation of amino acid bonds.

Q18: What equipment is needed to reconstitute peptides in a lab setting?

Standard laboratory supplies include sterile Bacteriostatic Water, alcohol prep wipes, and sterile mixing syringes.

Category 4: Featured Peptides & Related Research Compounds

Q19: Which metabolic research peptides does Onyx Peptides carry?

Our metabolic research catalog features high-demand GLP-1, GIP, and glucagon receptor agonists, including Retatrutide, Tirzepatide, and Semaglutide.

Q20: What are GLP-1 and GIP receptor agonists studied for?

These peptides are studied in clinical contexts for metabolic regulation, glucose-dependent insulin secretion, gastric emptying rates, and energy balance.

Q21: What recovery and tissue-repair peptides are available?

We offer tissue-repair compounds such as BPC-157 (Body Protection Compound-157) and TB-500 (Thymosin Beta-4), widely studied for tendon, muscle, and extracellular matrix repair mechanisms.

Q22: Can BPC-157 and TB-500 be researched together?

Yes, researchers frequently utilize BPC-157 and TB-500 in combination studies to observe potential synergistic cell-migration and angiogenesis outcomes.

Q23: What growth hormone secretagogues does Onyx Peptides offer?

Our growth hormone secretagogue catalog includes CJC-1295 (No DAC / With DAC), Ipamorelin, GHRP-6, and MK-677 (Ibutamoren).

Q24: What is the research profile of CJC-1295 and Ipamorelin?

When combined in research models, CJC-1295 (a GHRH analog) and Ipamorelin (a ghrelin mimetic) work together to stimulate endogenous growth hormone release without elevating cortisol or prolactin.

Q25: Does Onyx Peptides stock cognitive and anti-aging research compounds?

Yes, our catalog features anti-aging and neuro-protective research peptides including NAD+, Epithalon, GHK-Cu (Copper Peptide), and Semax.

Category 5: Offers, Discounts & Bulk Purchasing

Q26: Does Onyx Peptides offer bulk or wholesale pricing?

Yes. We offer tiered volume discounts for academic laboratories, clinical research facilities, and independent researchers placing multi-vial or bulk orders.

Q27: How can I access promotional discount codes?

Promotional codes are announced via our official newsletter and site-wide banner updates. First-time buyers can sign up for our newsletter to receive an instant welcome discount.

Q28: Are there stack or bundle savings available?

We offer curated Research Bundles (e.g., Recovery Stacks, GH Secretagogue Combos, and Reconstitution Kits) at a discounted price compared to individual vial purchases.

Q29: Do you offer free shipping on larger orders?

Yes, we offer complimentary standard domestic shipping on qualified orders exceeding our site threshold (e.g., orders over $150).
