Batch analytics are prepared by an independent lab and are provided with every order shipment.
Reverse-phase HPLC with UV detection. Purity numeric appears on every Certificate of Analysis.
Identity confirmed by LC-MS. Observed molecular weight matches theoretical within ± 1 Da.
Endotoxin ≤ 5 EU/mg by LAL. Sterility screened before lyophilization and vialing.

Shipping detailsEvery order is protected against damage, loss, or theft in transit. If your product arrives damaged, we’ll replace it at no cost. No claim forms, no back-and-forth.
Shop with confidenceA rigorous six-step process, from our manufacturing partners’ synthesis through independent third-party testing, ensures every peptide meets our exacting standards.
Our manufacturing partners test all raw materials for identity and purity before synthesis begins, verifying amino acid purity, solvent quality, and reagent specifications.
Partner facilities run solid-phase peptide synthesis (SPPS) in controlled cleanroom environments, following validated protocols with real-time monitoring.
Reverse-phase HPLC purification at our partners’ production facilities removes truncated sequences, deletion products, and residual solvents to deliver ≥ 98 % HPLC purity.
Purified peptide is freeze-dried into a stable lyophilized cake, then filled and crimped into amber glass vials under HEPA-filtered laminar flow to prevent contamination during vialing.
Every finished lot is sampled and sent to an ISO 17025-accredited third-party lab for identity (LC-MS), purity (HPLC-UV), Karl Fischer water content, acetate content, endotoxin (LAL), and appearance.
A Certificate of Analysis is issued for every lot and shipped with every order that contains it. Retention samples are archived for at least twelve months so any lot can be re-tested on request.
Share your unique referral code with fellow researchers. When they order, you earn a commission on qualifying purchases — they get a small discount at checkout, and you get credited automatically. Payouts are handled through a KYC-compliant processor.
By joining you agree to the Referral Partner Program Terms. Content restrictions apply — no medical, dosing, or human-use claims. See Section 4 for details.
Every listing carries the structured plain-English profile from the Trinity research guide — what the compound is, what it does at a mechanism level, why researchers study it, human study outcomes, side-effect notes, and what the online research community is discussing. We do not publish dosing information for any compound. Community-reported context is clearly separated from published research so you always know the source.
A kit contains ten identical-strength vials in a single order and is automatically 50 % off the retail per-vial price × 10. It is the only discount we offer and applies to every compound in the catalog. Every product page shows the full retail total struck through with the kit price in gold.
Products previously listed as Retatrutide, Tirzepatide, and Semaglutide appear on TSR Aminos as GLP-3, GLP-2, and GLP-1 respectively for catalog clarity. The internal SKU on your invoice preserves the original identity for laboratory traceability.
Sealed lyophilized vials are heat-stable and don't need refrigeration until reconstituted. After reconstitution, store at 2–8 °C, protected from light. For long-term storage of dry powder, −20 °C is preferred.
Yes. Every shipment includes the CoA for the specific lot you received: HPLC purity, mass-spectrometry identity, Karl Fischer water content, acetate content, endotoxin, and appearance. Retention samples are held for at least twelve months.
No. All TSR Aminos products are supplied strictly for in-vitro laboratory research. They are not drugs, not dietary supplements, and are not intended to diagnose, treat, cure, or prevent any disease. Nothing on this site is medical advice.
Add vials or 10-vial kits to your cart and open Checkout to enter shipping and choose a payment rail (USDC on Solana or Zelle; credit-card checkout is on the way). You'll receive an order reference plus the exact payment address. If you prefer, you can still call 909-322-6375 or email support@tsraminos.com with your SKU, quantity, and shipping details — product pages have call and email buttons pre-filled with the compound name and strength.
