Orbitrex Peptides (orbitrexpeptide.is) is a US-based research-compound supplier. Two things about its documentation are worth knowing before anything else: the certificates carry a search code that resolves on the testing laboratory’s own website rather than only on Orbitrex’s, and the panel those certificates run is deeper than most. Compounds by research area:
- Metabolic & Weight Loss
- Retatrutide (3G-RT), Tirzepatide (G2-TRZ), Semaglutide (1G-SGT), Cagrilintide (Cag), Survodutide, AOD-9604, MOTS-C, 5-Amino-1MQ
- Recovery & Tissue Repair
- BPC-157, TB-500, Wolverine (BPC-157 + TB-500)
- Growth Hormone
- CJC-1295 (no DAC) + Ipamorelin, Sermorelin, Tesamorelin, SomatoPulse (Tesamorelin + Ipamorelin)
- Skin Health & Anti-Aging
- GHK-Cu, Melanotan I, Melanotan II, GLOW, KLOW
- Gut Health & Immunity
- KPV, Thymosin Alpha-1, VIP, LL-37
- Sleep & Recovery
- DSIP
- Longevity
- NAD+ and buffered NAD+, Glutathione, Epitalon, Pinealon, Cortagen, ARA-290, Cartalax, Vilon, FOXO4-DRI
- Sexual Health
- PT-141, Oxytocin, Kisspeptin
Orbitrex labels its GLP-class metabolic compounds with coded names, and each decode comes from the certificates rather than from the naming convention: the certificate for 3G-RT names Retatrutide in plain text, the certificate for G2-TRZ names Tirzepatide, and the certificate for 1G-SGT names Semaglutide. Cag is documented as Cagrilintide on its own certificate. Survodutide is sold under its own name. We list each compound under both its name and its code — “Retatrutide (3G-RT)” — so a reader searching Orbitrex’s store for the coded name still lands on the right compound.
Orbitrex publishes 195 certificates, with multiple dated batches for a given product rather than a single fixed file — the 20 mg Retatrutide listing alone carries eight. Testing is spread across several named laboratories, each named on the certificates it issues: Freedom Diagnostics covers the largest share, with further certificates from ILS Laboratories, Kovera Labs, Vanguard Laboratory and TrustPointe Analytics.
The Freedom Diagnostics certificates run an unusually broad panel for this catalog. Alongside identity by LC-MS, purity by HPLC with UV detection, and measured net peptide content, they report bacterial endotoxin by USP <85> LAL assay run in duplicate, microbial screening by PCR, elemental impurities by ICP-MS covering arsenic, cadmium, lead and mercury, and a fentanyl screen. They also assay four vials from the batch separately, printing a purity and a content figure for each rather than a single number for the lot. The ILS Laboratories certificates run their own panel, covering purity, identity and quantitation by HPLC together with an endotoxin test, elemental impurities by ICP-MS and a fentanyl screen.
The basis for the first point is worth setting out, because it is what separates a certificate a reader can check from one they cannot. Every Freedom Diagnostics certificate prints a search code. We took two — ORBI2607220001, a Semaglutide lot, and Orbi2608180461, a Retatrutide lot — and resolved each directly on Freedom Diagnostics’ own domain. Both returned the laboratory’s own copy of the report, byte-for-byte identical to the file Orbitrex publishes. The check runs against the laboratory rather than against the vendor, and it is a check any reader can repeat. The ILS Laboratories certificates print their own access code for verification at that laboratory.
The certificates for the GLP-class compounds are published at fixed addresses, which we link here directly: Retatrutide 10 mg, lot ORB-3R1096; Tirzepatide 15 mg, lot 2G15726; Semaglutide 10 mg, lot 1G10826; and Cagrilintide 10 mg, lot CAG100326.
Two points of context. None of these laboratories prints an accreditation on the certificates we read, so none is claimed here — the strength of the record is the independent, externally verifiable check on the laboratory’s own domain. Orbitrex states that its products are “verified at >99% purity through independent third-party testing”; the certificates report the measured result for each lot, which is the figure to read. Orbitrex is US-based and ships to all 50 US states and Washington, D.C. All products are sold for laboratory and research use only.
