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 & GLP-1
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 (a blend of BPC-157 and TB-500)
Growth Hormone
GH Stack, Sermorelin, Tesamorelin, SomatoPulse (a blend of Tesamorelin and Ipamorelin)
Cognitive & Nootropic
Semax, Selank, N-Acetyl Semax Amidate, N-Acetyl Selank Amidate, Adamax
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 sells retatrutide as 3G-RT, tirzepatide as G2-TRZ, semaglutide as 1G-SGT and cagrilintide as Cag — each named in plain text on its own certificate. Survodutide is sold under its own name.

Orbitrex’s certificate page states 173 certificates across 58 products — the vendor’s own figure, printed verbatim at orbitrexpeptide.is/coas/ — 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.

  • NAD+ — 99.88%
  • Net Peptide Content — Vial 1: 576.12 mg; Vial 2: 569.85 mg; Vial 3: 563.05 mg; Average Net Peptide: 569.67 mg

Tirzepatide 60mg · lot ZG601125A

Passed

Freedom Diagnostics · tested 27 November 2025 · certificate Orbi2511240086

  • Passed: Replicate 1 — Pass (spec ≤ 0.05 EU/mL)
  • Passed: Replicate 2 — Pass (spec ≤ 0.05 EU/mL)

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.

Finnrick rates Orbitrex Peptides 71% across 46 tests (read 30 September 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.

Frequently Asked Questions

What peptides does Orbitrex Peptides carry?
Orbitrex carries a research catalog spanning GLP-class metabolic compounds — Retatrutide, Tirzepatide and Semaglutide under the coded names 3G-RT, G2-TRZ and 1G-SGT, plus Cagrilintide and Survodutide — alongside AOD-9604, MOTS-C and 5-Amino-1MQ, recovery peptides (BPC-157, TB-500 and a blend of BPC-157 and TB-500 sold as Wolverine), growth-hormone secretagogues (CJC-1295 no DAC with Ipamorelin, Sermorelin, Tesamorelin, and a blend of Tesamorelin and Ipamorelin sold as SomatoPulse), Semax and Selank with their N-acetyl amidate forms, Adamax, GHK-Cu, Melanotan I and II, GLOW and KLOW, KPV, Thymosin Alpha-1, VIP, LL-37, DSIP, NAD+ and buffered NAD+, Glutathione, Epitalon, Pinealon, Cortagen, ARA-290, Cartalax, Vilon, FOXO4-DRI, PT-141, Oxytocin and Kisspeptin.

Is Orbitrex Peptides third-party tested?
Yes. Orbitrex’s COA page states 173 certificates across 58 products, with multiple dated batches per product, issued by several named laboratories — Freedom Diagnostics covers the largest share, with further certificates from ILS Laboratories, Kovera Labs, Vanguard Laboratory and TrustPointe Analytics. The Freedom Diagnostics certificates report identity by LC-MS, purity by HPLC-UV, measured net peptide content, bacterial endotoxin by USP <85> LAL run in duplicate, microbial screening by PCR, elemental impurities by ICP-MS, and a fentanyl screen, with four vials from the batch assayed separately. Each also prints a search code that resolves on Freedom Diagnostics' own domain: we resolved two — ORBI2607220001, a Semaglutide lot, and Orbi2608180461, a Retatrutide lot — and both returned the laboratory's own copy byte-for-byte identical to the file Orbitrex publishes. None of these laboratories prints an accreditation on the certificates we read, so none is claimed here.
What do Orbitrex Peptides' 1G-SGT, G2-TRZ and 3G-RT codes mean?
They are Orbitrex's coded names for its GLP-class metabolic compounds, 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, and Survodutide is sold under its own name. Prof. Peptide asserts a decode only from evidence such as a molecular weight, formula, CAS number or a self-identifying specification — a naming convention on its own is corroboration, not proof.
Where does Orbitrex Peptides ship?
Orbitrex ships to all 50 US states and Washington, D.C. Its published address is in Flower Mound, Texas. All products are sold for laboratory and research use only.
