Looking for an alternative to Peptide Sciences?
Peptide Sciences is currently limited availability. Peptide Sciences built its catalog around US-domestic supply of research peptides. Buyers who relied on Peptide Sciences for consistent purity and broad compound coverage need a replacement with documented analytical data and similar SKU breadth.
Research Use Only — Not FDA-Approved
All Orion compounds are for in-vitro laboratory research only and are not for human consumption.
Why Orion as a Peptide Sciences replacement
- 16 in-stock SKUs plus 6 in transit covering metabolic, tissue-signaling, longevity, neuropeptide, and dermatological research
- ≥98% purity specification per batch, with the measured value recorded on the batch COA
- Reversed-phase HPLC + mass spectrometry on every lot
- No subscription, no minimum, single-vial pricing available on every SKU
- Researcher attestation at checkout — clear in-vitro research framing throughout

FAQ
Is Orion a direct replacement for Peptide Sciences?
Orion is a research-supply vendor with overlapping catalog coverage to Peptide Sciences. We do not represent or claim affiliation with Peptide Sciences. We provide third-party-tested research compounds with batch-specific Certificates of Analysis. Material is for in-vitro research use only.
How is purity verified?
Every batch is tested by reversed-phase HPLC for purity and confirmed by mass spectrometry against the theoretical molecular weight. The batch-specific COA documents the measured purity value (minimum specification 98%) and is available with every order.
What's the typical shipping timeline?
USPS-tracked fulfillment within 1–2 business days of confirmed payment. Tracking provided. Returns are not accepted on opened or temperature-compromised material per the refund policy.
Which payment methods are available?
USDT, USDC, PYUSD, Bitcoin, and Ethereum through NOWPayments; Zelle for US bank-to-bank transfers up to $1,500 per order. Crypto payments are auto-confirmed on-chain.
Are these compounds for human use?
No. All Orion research compounds are for in-vitro laboratory research only. They are not FDA-approved for any therapeutic, diagnostic, or clinical use, and they are not for human consumption. Each checkout requires a five-point researcher attestation.
