What is PEP-TSM-G?
PEP-TSM-G is a 44-amino-acid analogue of growth-hormone-releasing hormone with a modification at the N-terminus that protects it from enzymatic breakdown. It is used in research on the GHRH receptor, growth-hormone and IGF-1 signalling, and visceral adipose tissue models. Pepstral supplies PEP-TSM-G as a lyophilized powder, 10 mg net peptide per vial, tested by an independent US laboratory before the lot is listed.

What is PEP-TSM-G studied for?
- GHRH receptor pharmacology
- Growth-hormone and IGF-1 axis studies
- Visceral adipose tissue models
- Comparisons against CJC-1295 and native GHRH
All applications above are in-vitro or preclinical research contexts. PEP-TSM-G is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot TESA10-0803 show?
Every lot of PEP-TSM-G is tested by an independent US laboratory before it is listed. The report for lot TESA10-0803 is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot TESA10-0803 result |
|---|---|---|
| Identity | LC-MS/MS | Conforms |
| Content | HPLC quantitation | 10.18 mg |
| Purity | RP-HPLC (214 nm) | 99.79% |
| Endotoxin | USP <85> | <0.05 EU/mL |
| Heavy metals | USP <232> | <0.01 ppm |
How is PEP-TSM-G handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
Frequently asked questions
How does PEP-TSM-G differ from CJC-1295?
Both are GHRH analogues. PEP-TSM-G carries a trans-3-hexenoic acid group at the N-terminus for enzyme resistance, while CJC-1295 uses amino-acid substitutions.
What does lot TESA10-0803 report?
99.79% purity by RP-HPLC (214 nm), identity confirmed by LC-MS/MS, content 10.18 mg by HPLC quantitation, endotoxin <0.05 EU/mL, heavy metals <0.01 ppm. Certificate COA7630, issued 17 August 2026 by Bioviridian Inc.
Is PEP-TSM-G part of a bundle?
Yes. The GH axis set pairs it with the CJC-1295 and Ipamorelin blend as one order; each vial keeps its own certificate and its own catalogue price.
Is PEP-TSM-G for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
Also ordered as part of gh axis set and metabolic axis.
