QUALITY & TESTING
Are your products third-party tested?
Yes. Every product undergoes quality control and verification. Certificates of Analysis (COAs) are attached directly to each product listing — no email request required. A COA includes HPLC purity data and identity verification confirming the compound matches what’s on the label. You can review the COA for any product before you purchase.
Where do I find the COA for a product?
COAs are attached directly on each individual product page. Click into any product listing and you’ll find the COA linked there. You do not need to contact us to access this documentation — it’s available to everyone before purchase.
How are products handled and stored before shipping?
All compounds are handled in small batches under strict verification standards to maintain consistency and purity. Products are stored in conditions appropriate to each compound’s stability requirements and packaged with care to protect integrity during transit.
What form do products come in?
All research peptides and bundles come as lyophilized (freeze-dried) powder in sealed vials, unless otherwise specified. Our nasal spray products come pre-mixed in solution — no reconstitution required for those. Reconstitution supplies such as Bacteriostatic Water are available in our Research Supplies section when in stock.
RESEARCH SUPPORT NETWORK
What is the Research Support Network?
Every Starline Chems customer receives access to our research support network — a certified coach specializing in training, nutrition, and research protocol guidance — included free with every order. Contact details are provided directly in your order confirmation email. This is not an upsell, not an affiliate arrangement, and not a paid add-on.
Is the coach affiliated with Starline Chems financially?
No. The coaching partnership is a mutual referral arrangement — we promote each other but neither party earns commission from the other. The coach’s services are priced independently and Starline Chems receives no revenue from them.
What can the coach help with?
The coach specializes in training optimization, nutritional frameworks, and research protocol guidance. This is educational and informational support — not medical advice. For any health concerns or medical decisions, always consult a licensed healthcare professional.
ORDERING & PAYMENT
Do you accept card payments?
Yes! Currently our primary payment method is our PayPal option at checkout. This gives our customers the highest level of privacy and transaction security. Contact us directly at Starlinesales@starlinechems.com if you have questions about payment options.
Can I cancel or modify my order?
Orders can be canceled or modified before they ship. Once an order has been dispatched, it cannot be altered or canceled. If you need to make changes, contact us immediately at Starlinesales@starlinechems.com — the sooner you reach out, the more likely we can catch it before dispatch.
What is your return and refund policy?
Due to the nature of research compounds, all sales are final once products have shipped. If your order arrives damaged, incorrect, or incomplete, contact us immediately with photos and your order details. We will make it right.
PRODUCTS & CATALOG
What categories of peptides do you carry?
Our catalog covers six research categories: Weight Loss & Metabolic (GLP-class compounds), Recovery & Healing (BPC-157, TB500, KLOW, KPV), Cognitive & Nootropic (Selank, Semax), Longevity & Mitochondrial Health (NAD+, MOTS-c), Skin, Hair & Cosmetic (GHK-CU, Melanotan II, Glutathione), and Growth Hormone Secretagogues (Tesamorelin, Ipamorelin). We also carry Nasal Spray formats of select compounds — Semax, Selank, Melanotan II, and a Semax+Selank combo — pre-mixed, no reconstitution required.
What is the difference between nasal sprays and lyophilized vials?
Lyophilized powder vials require reconstitution with Bacteriostatic Water or Acetic Acid before use. Nasal spray formats are pre-mixed in solution and ready to use immediately — each spray delivers a precise 200mcg actuation. Nasal delivery has been studied for certain compounds like Semax and Selank due to the olfactory pathway’s proximity to the central nervous system.
Some products show as sold out — when will they restock?
Use the “Notify Me When Available” button on any sold-out product page to receive an email the moment it’s back in stock. You can also email us at Starlinesales@starlinechems.com to ask about expected restock timelines for specific compounds.
Are bundles available if one compound is sold out?
Bundles that contain a sold-out compound are listed as unavailable until all components are back in stock. We don’t ship partial bundles. Use the “Notify Me” feature on the bundle page to be alerted when it’s fully available again.
Why are some compounds listed under catalog codes like GLP3-RT?
Some compounds are listed under internal catalog codes for compliance purposes. GLP3-RT references a GLP-1/GIP dual agonist class compound. GLP2-TZ references a GLP-2 receptor agonist class compound. Email us if you have questions about what a specific catalog code corresponds to.
Are your products legal in my state?
It is the purchaser's responsibility to verify that the products they are ordering are legal to purchase, possess, and use in their jurisdiction. Regulations vary by state and locality. Starline Chems does not ship to purchasers in jurisdictions where the ordered product is prohibited by law. If you are uncertain about the legal status of a compound in your state, we recommend consulting legal counsel before placing an order.
What is the FDA regulatory status of your products?
Many of the compounds we supply are classified by the FDA as unapproved new drugs or as Category 2 Bulk Drug Substances under 503A of the Federal Food, Drug, and Cosmetic Act. This means they are not approved for therapeutic use in humans and may not be compounded by licensed pharmacies for human use. Our products are sold strictly for in vitro laboratory research only.
Do you verify buyer qualifications?
By completing a purchase, all buyers represent that they are qualified researchers or laboratory professionals aged 21 or older with the proper facilities and expertise to handle research compounds. Starline Chems reserves the right to request verification and to refuse or cancel any order.
