Growth Hormone Support
Tesamorelin is a stabilised 44-amino-acid analogue of human growth hormone-releasing hormone (GHRH) bearing a trans-3-hexenoic acid modification at the N-terminal tyrosine residue. The acyl group confers resistance to dipeptidyl peptidase-IV cleavage, extending plasma half-life relative to native GHRH and prolonging stimulation of pituitary GHRH receptors. Published preclinical and clinical literature has characterised its pharmacokinetics, downstream growth-hormone and IGF-1 pulsatility, and effects on visceral adipose tissue and hepatic fat in randomised trials of HIV-associated lipodystrophy. AeroPeptides supplies tesamorelin for in vitro and ex vivo investigation of GHRH-receptor pharmacology, endocrine signalling, and adipose-tissue biology; findings from approved clinical populations should not be extrapolated to other contexts. For laboratory and research use only.

Technical specifications
Compound Information
N-modified GHRH analogue (44 amino acids)
Storage & Stability
Lyophilized (powder)
-20°C • long-term stable in sealed lyophilized form
Reconstituted
2-8°C • use within 30 days of reconstitution
Light
Protect from light during storage and reconstitution
Room temperature
Short-term tolerant during shipping; minimise extended exposure above 25°C
Dosing in the literature
Observational summary of values reported in published research. Not a guide for human or animal use.
Reconstitution
Typically 1–2 mL bacteriostatic water per 10 mg vial, yielding a ~5–10 mg/mL working concentration in research preparations.
Published protocols
Falutz et al. 2007 (NEJM, PMID 18057338) and the pooled phase 3 analysis (Falutz et al. 2010, JAIDS, PMID 20554713) used SC injections of 2 mg/day in HIV-associated lipodystrophy research cohorts. Stanley et al. 2011 (JCEM, PMID 20943777) characterised GH pulsatility and insulin-sensitivity effects at 2 mg/day SC in healthy men.
Half-life
~26–38 minutes in plasma following SC administration, as characterised by Chen et al. 2015 (Br J Clin Pharmacol, PMID 25358450) population PK analysis. The trans-3-hexenoyl modification confers DPP-IV resistance relative to native GHRH but does not extend half-life to the multi-day range seen with albumin-binding analogues.
Post-reconstitution stability
~28 days at 2–8 °C in BAC-water solution.
Half-life from Chen et al. 2015 (PMID 25358450). Published dose levels from Falutz et al. 2007 (PMID 18057338) and Falutz et al. 2010 (PMID 20554713) phase 3 trials in HIV-lipodystrophy cohorts.

Researcher FAQ
No. Aero Peptides materials are sold exclusively for in-vitro research and laboratory analytical use. They are not intended to diagnose, treat, cure, or prevent any disease, and are not approved for human or animal administration.
By placing an order, you confirm that you are a qualified researcher and that the material will be used in accordance with all applicable institutional and jurisdictional regulations.
Each lot is independently tested for identity, purity, and mass using HPLC and mass spectrometry. The COA lists the lot number, test date, assay results, and the laboratory that performed the analysis.
Public COA documents are being prepared. In the meantime, you can request a COA for your specific lot and we’ll email it within 1 business day.
Orders ship quickly after your order is placed, from the US. Lyophilized peptides are shipped with insulation appropriate to season; short-term ambient excursions during transit do not measurably affect potency.
On receipt, store at −20°C in the sealed vial until reconstitution. See the handling matrix for full storage parameters. Tracked shipping is included; we ship to all US states and most international destinations.
Most peptides are reconstituted with bacteriostatic water (BAC). The volume depends on the target working concentration. Use our Peptide Calculator to compute volume, U-100 insulin syringe units, and doses per vial from peptide mass and target dose.
Once reconstituted, store at 2–8°C and use within 30 days. Protect the vial from light during storage and handling.
Because peptides are temperature-sensitive research materials, we cannot accept returns of opened or unsealed vials. If a shipment arrives damaged or the seal is broken on arrival, contact us within 7 days and we’ll replace or refund.
See our full returns policy for details.
