Janoshik Analytical
RecommendedThe community standard, with a public results archive and a per-compound price list.
Before you send a sample
- Samples ship from Canada to the Czech Republic, so budget for international transit and customs.
- Prices are per compound and the spread is wide. Check the published list for yours before ordering.
- No published turnaround window and no named accreditation body.
The most widely used independent laboratory in the peptide research community, and the reference point most vendor certificates are measured against. Janoshik publishes a price for every compound it will run, maintains a public results archive so a certificate can be checked against the laboratory's own record rather than taken on trust, and has been analysing performance compounds for over ten years. It is the only entry here whose per-compound price you can look up before you have spoken to anybody.
Services and pricing
US$215 to US$450 a peptide, published per compound, with blends US$320 to US$800.
Single peptide analysis
US$215–$450, per compoundComprehensive purity and composition analysis, reporting identity and the amount of peptide present. BPC-157, arg-BPC-157, CJC-1295 with or without DAC, ipamorelin, GHRP-2/6, PT-141, TB-500, melanotan II and AOD-9604 sit at US$215. Semax, selank, epithalon, DSIP, GHK-Cu, sermorelin, tesamorelin, glutathione and thymosin alpha-1 sit at US$290. Cagrilintide, KPV, MOTS-C, kisspeptin, LL-37, oxytocin, SS-31, NAD+, dihexa, VIP, hexarelin, melanotan I and the bioregulator series sit at US$450.
Common GLP-1 blind test
US$360Identifies which of semaglutide, tirzepatide or retatrutide a sample actually contains. This is the GLP-1 route at Janoshik: it does not publish individual semaglutide, tirzepatide or retatrutide analyses.
Blend analysis
US$320–$800, per blendBPC-157/TB-500 and both CJC-1295/ipamorelin blends at US$320; GLOW (identity and amount, peptide purity not included) at US$500; the thymosin alpha-1/thymalin/thymulin blend at US$600; CagriSema at US$630; KLOW at US$800.
Human growth hormone analysis
US$360, or US$500 with dimerAmount and purity at US$360. The US$500 version adds dimer and higher-molecular-weight protein analysis. The AOD-9604 and rHGH fragment tests are US$215 in water and US$340 with LCMS plus CHNS.
Bacterial endotoxin
US$180Measurement up to 10 EU per vial. A separate vial is preferred rather than sharing the one used for purity.
Sterility testing (TAMC + TYMC)
US$290Total aerobic microbial count and total yeast and mould count.
Heavy metals screening (As, Cd, Pb, Hg)
US$145The four-metal screen, ordered alongside or instead of purity work.
GCMS/LCMS contamination screening
US$205Contamination screening under the harm-reduction service line.
Bacteriostatic water and benzyl alcohol analysis
US$145Analysis of the diluent rather than the compound.
Methods
- Chromatography with mass-spectrometric detection for identity and composition
- CHNS elemental mass report, available standalone
- Kinetic endotoxin measurement, reported per vial
- Microbial enumeration for total aerobic count and total yeast and mould count
- Blind screening panels for GLP-1 peptides, anabolic steroids and SARMs
What it will test
- Peptides, including the full Khavinson bioregulator series and the N-acetyl and amidate variants
- Anabolic steroids, including blind screening for raws, oils and orals
- SARMs and related compounds, and SERMs
- Sexual health compounds
- Harm reduction: heavy metals, contamination screening, endotoxin, sterility
What the certificate carries
- Results published to a public archive, so a certificate can be matched against the laboratory's own record
- Reports issued anonymously; the laboratory states 100% anonymous and secure test reports
Best for
Cross-checking a vendor's own Janoshik certificate, and for compounds where a published community price and a public results archive matter more than domestic turnaround.
Shipping from Canada: International. A Canadian sample crosses to the Czech Republic, so budget for transit and customs.
Janoshik Analytical questions
Can I get semaglutide or tirzepatide tested individually?
Not as a named single-compound test. The published GLP-1 route is the US$360 blind test, which identifies which of semaglutide, tirzepatide or retatrutide is actually present.
Why is one peptide US$215 and another US$450?
Janoshik prices per compound rather than flat. Common compounds with established methods sit at the low end; rarer ones, including the bioregulator series, sit at US$450.
