Research use and compliance
What does “Research Use Only” (RUO) mean?
RUO means our products are sold strictly for laboratory and in-vitro research by qualified researchers. They are not drugs, foods, supplements or cosmetics, and they are not intended to diagnose, treat, cure or prevent any disease.
Can these products be used in humans or animals?
No. Nothing we sell is for human or animal consumption, injection, or any other form of administration. Purchasing from Amino Annex confirms you will use products only in a controlled research setting.
Do you give dosing, reconstitution or protocol advice?
No. We can’t advise on dosing, administration or use protocols, and our team will not answer questions that suggest human or animal use. We’re happy to help with product specifications, documentation, orders and shipping.
Who can buy from Amino Annex?
Buyers must be at least 21 years old and purchasing for legitimate research purposes. At checkout you’ll confirm both. We may cancel orders that appear to be for personal use.
Are your products FDA approved?
No. Our products are research chemicals and have not been evaluated or approved by the FDA for any use. Statements on this site have not been evaluated by the FDA.
Rewards
How does the Amino Annex rewards program work?
Our rewards program lets you earn points on every order and turn them into discounts. Create a free account or log in, and you’re enrolled automatically. You can check your points any time under My Account -> Points & Rewards.
How do I earn points?
You earn 1 point for every $5 you spend. Points are added to your account when your order is completed. For example, a $100 order earns 20 points. Points are only earned on orders placed while you’re logged in.
How do I redeem my points?
Every 100 points can be redeemed for a $25 off coupon. Open your rewards page in My Account or the rewards panel, choose the $25 off reward, and redeem it. Your coupon will appear in your account. Apply it at the cart or checkout, and the discount comes off your order total.
How does the referral bonus work?
Share your personal referral link, found on your rewards page. When a friend places their first order through your link, you both receive a 25% points bonus based on the points that order earns. For example, if your friend’s first order earns 40 points, they get 10 bonus points on top, and you get 10 bonus points too. The bonus applies only to a referred friend’s first purchase.
Do my points expire, and what happens if I return an order?
Points do not expire. If an order is cancelled or returned no points are awarded. In rare instances, a voucher applied to an order that gets cancelled can become unavailable. Please contact us at info@aminoannex.com if this happens so we can issue a new voucher code.
Can I combine reward coupons with other discounts?
Reward points cannot be combined with other discounts. Reward coupons have no cash value and can’t be exchanged for cash.
Quality and testing
How pure are your peptides?
Every lot is tested by HPLC, and we only release lots that meet our minimum purity of ≥98%. The exact purity for your lot is printed on its Certificate of Analysis.
What is a Certificate of Analysis (COA), and where do I find one?
A COA is the lab report for a specific production lot. It shows identity (mass spectrometry), purity (HPLC), lot number and test date. Each vial label carries a lot number; enter it in our COA lookup to view the matching report, or find COAs on each product page.
Who tests your products?
Lots are tested by Freedom Diagnostics. COAs list the testing lab so results can be checked.
What’s the difference between batch average content and the vial amount?
The amount on the label (for example 10 mg) is the expected weight of lyophilized material.Batch average content is the average content accross several conformity vials, with the rest being counter-ions and residual moisture that are normal in peptide synthesis. Where tested, batch average appears on the COA and the label.
Storage and handling
What form do products arrive in?
Peptides ship as a lyophilized (freeze-dried) powder in a sealed, crimp-capped glass vial. The powder may look like a small puck, flakes or a thin film, and it can shift during transit. That’s normal and doesn’t affect the material.
How should I store products when they arrive?
For long-term storage, keep sealed lyophilized vials frozen at −20 °C, dry and away from light. For short periods, refrigeration at 2–8 °C is generally fine. Let a vial reach room temperature before opening to limit condensation. Always follow the storage guidance on the product page and SDS.
My order wasn’t shipped cold. Is it still OK?
Yes. Lyophilized peptides are stable at ambient temperature for the length of normal transit, so cold packs aren’t needed. Move vials into proper storage once they arrive.
Orders and shipping
Where do you ship?
We currently ship to all 50 US States, Canada and Puerto Rico.
How fast will my order ship?
Orders placed before 2:00PM Central on business days usually ship same day. Typical delivery takes 2–5 business days after shipping but can take longer due to unforseen circumstances. We cannot control carrier delivery times.
Will I get tracking information?
Yes. You’ll receive an email with a tracking number as soon as your order ships. You can also see order status any time under My Account.
How is my order packaged?
Orders ship in plain, unbranded outer packaging with vials padded to prevent breakage.
Can I change or cancel my order?
You can change your order within 30 minutes of placing it. After we cannot guarantee modifications or cancellations.
Payments, returns and support
What payment methods do you accept?
We accept ACH/e-check, Zelle and crypto. All payments are processed securely, and we never store full card details.
