Research Peptide Oral Sprays
This collection covers our ready-to-use research oral sprays, all in the shelf-stable PRO formulation: GLP-3 (RT) PRO Oral Spray (Retatrutide) and GLP-2 (TR) PRO Oral Spray (Tirzepatide), two peptide combinations (BPC-157 / TB-500 and MOTS-c / SS-31), and single-compound sprays of GHK-Cu and Cartalax. Each spray comes in a 10 mL spray bottle, with the amount of compound printed on the label and listed on the product page.
What Is a Peptide Oral Spray?
A peptide oral spray is a research compound supplied already prepared in a spray bottle, so researchers can work with it straight away, without the reconstitution step a lyophilized vial requires. The sublingual sprays in this collection are labeled for the sublingual oral-spray format. All sprays are sold strictly for laboratory and in vitro research and are not for human or veterinary use.
What Does PRO Mean?
PRO is the shelf-stable spray formulation. Every spray in this collection has a 12-month shelf life and needs no refrigeration, which keeps storage and handling simple over the course of a study.
Our Research Oral Sprays
- GLP-3 (RT) PRO Oral Spray (Retatrutide) (20 mg in 10 mL): retatrutide, used in models of the GLP-1, GIP and glucagon receptor systems.
- GLP-2 (TR) PRO Oral Spray (Tirzepatide) (20 mg in 10 mL): tirzepatide, studied at the GLP-1 and GIP receptors.
- BPC-157 / TB-500 PRO Sublingual Oral Spray (20/20 mg in 10 mL): two peptides studied in tissue repair and recovery research, at a fixed ratio.
- MOTS-c / SS-31 PRO Sublingual Oral Spray (25/25 mg in 10 mL): the mitochondrial-derived peptide MOTS-c combined with SS-31.
- GHK-Cu Sublingual Oral Spray (50 mg in 10 mL): the copper-binding peptide complex GHK-Cu, studied for collagen synthesis and tissue regeneration.
- Cartalax 10 Sublingual Oral Spray (10 mg in 10 mL): Cartalax in a ready-to-use sublingual spray.
Oral Sprays vs. Lyophilized Vials
Lyophilized vials hold freeze-dried powder that researchers reconstitute to their own concentration and store at −20 °C. Oral sprays trade that flexibility for convenience: the amount is set, the spray is ready to use and the PRO formulation needs no refrigeration. Retatrutide, tirzepatide, BPC-157, TB-500, MOTS-c and GHK-Cu are also available as lyophilized vials, so studies can compare formats.
Why Researchers Use PRO Oral Sprays
- No reconstitution step, so less preparation time and handling
- A 12-month shelf life with no refrigeration required
- A fixed, labeled amount in every 10 mL bottle
- Combination sprays that keep the ratio between peptides identical from bottle to bottle
Choosing an Oral Spray by Research Area
- Metabolic and endocrine receptor signaling: GLP-3 (RT) PRO or GLP-2 (TR) PRO
- Tissue repair and recovery: BPC-157 / TB-500 PRO
- Cellular energy and metabolism: MOTS-c / SS-31 PRO
- Collagen synthesis and tissue regeneration: GHK-Cu
How to Store Peptide Oral Sprays
No refrigeration is required: keep each bottle capped, upright and away from heat and direct light, and use it within its 12-month shelf life. The storage notes for each spray are listed on its product page.
Testing and Lot Documentation
Each lot is independently tested by reverse-phase HPLC and mass spectrometry. Until a lot's certificate is published, the product page reads "Lot COA coming soon"; published certificates are added to our COA library, searchable by compound or lot number.
