Overview
Guru Peptides (gurupeptides.com) is a US research-supply vendor that states it ships from a single warehouse in the United States. Its store runs wider than peptides — it also sells SARMs, research chemicals and lab equipment — and Prof. Peptide covers the peptide catalog only. The facts on this page were read from Guru's own pages on 29 September 2026 and 6 October 2026, and each section says which.
Guru Peptides catalog & prices
On 6 October 2026 Guru's shop listed 61 products. Its own category counts were Peptides 34, Catalog Chemicals 18, SARMs 12, Bulk Chemicals 2 and Lab Equipment 1; those add to more than 61, so some products sit in more than one category.
Peptides are sold as lyophilised vials at stated mg weights. Among the compounds named on Guru's own listings and certificates, grouped by Prof. Peptide's research categories:
- Metabolic & GLP-1
- Semaglutide, Tirzepatide, Retatrutide, MOTS-c, 5-Amino-1MQ, HGH Fragment 176-191
- Growth Hormone
- CJC-1295, Tesamorelin, Ipamorelin, GHRP-2, MK-677
- Skin Health & Anti-Aging
- GHK-Cu, Melanotan II
- Gut Health & Immunity
- KPV
Three peptide listings carry coded names: Guru sells semaglutide as GLP-1 (S), tirzepatide as GLP-2 (T) and retatrutide as GLP-3 (R). Each product's certificate filename names the compound outright, and the batch prefixes on Guru's results table — SM, TZ and RT — corroborate it.
Guru's store does not allow automated price reads, so Prof. Peptide holds no Guru price data and no price table appears here.
Testing: Labs & Certificates of Analysis
Guru publishes a dedicated 3rd Party Test Results page rather than placing certificates in product galleries. On 29 September 2026 it listed 18 batch reports — 14 marked current and 4 marked previous — as a table giving, for each, the product, the batch number, the test date, the laboratory, a result summary and a link to the certificate. As of 14 October 2026, Guru Peptides's certificates couldn't be checked at the lab's own records.
The 14 current reports are attributed to BT Labs and dated 20 August 2026, each linking a signed PDF on Guru's own domain whose filename carries the laboratory report number, the compound and the batch. They are described as covering purity by HPLC and identity by FTIR. The 4 previous reports are attributed to MZ Biolabs, dated April 2024, and cover SARMs rather than peptides. For at least one product the results table and the certificate filename give different batch numbers — KPV005 and KP0005.
None of these reports has been checked against a laboratory's own records. BT Labs runs a public verification portal keyed on the report number, but it sits behind a CAPTCHA challenge, and Prof. Peptide does not complete CAPTCHAs. Both laboratories are therefore recorded as named by Guru rather than verified, and this page carries no verification panel.
Payment and shipping
As read on 29 September 2026: Guru states orders ship within 24 hours of payment, with 48 hours allowed for orders outside the USA, and that USPS tracking arrives in the confirmation email.

Its returns page, read the same day, accepts returns due to damage that is Guru's fault or manufacturer's defects.
