Pre-filled Nasal Spray Peptides — Coming Soon
Coming soon — our pre-filled nasal spray range is being finalised (labels and packaging). Vials of every peptide below are available to order now; the nasal spray format will be enabled as soon as stock is ready.
A curated selection of research peptides available as pre-filled nasal sprays — already reconstituted and ready to use in a sterile 30 ml bottle. Prefer the standard format? Each peptide is also available as a lyophilised research vial. Every batch is independently HPLC tested at ≥99% purity and dispatched from our UK facility. Strictly for in-vitro research use only — not for human use.

Pre-filled nasal sprays — ready to use (coming soon)
The pre-filled nasal spray option will be available shortly — each peptide arrives already reconstituted in a sterile 30 ml nasal spray bottle, ready for in-vitro research use straight away. Until the pre-filled format launches, you can order the lyophilised vial format and reconstitute with sterile saline. Add solvent slowly down the inside wall of the vial, swirling gently until dissolved. Our peptide reconstitution calculator gives exact volumes for your target concentration.

Which of your peptides are available as nasal sprays?
The peptides most commonly used in nasal spray studies from our range are MT-1, MT-2, PT-141, Selank, Semax, DSIP, NAD+ and Glutathione. The pre-filled nasal spray format is coming soon; the standard lyophilised research vial is available to order now for each of these peptides.
What does pre-filled nasal spray mean?
Our pre-filled nasal sprays are supplied already reconstituted in a sterile 30 ml nasal spray bottle — ready to use straight away for in-vitro research. No separate mixing, solvent, or empty bottle is needed.
What solvent should I use if I buy the vial format?
If you choose the lyophilised vial format, nasal spray research protocols typically use sterile saline — not acetic acid water. Add the solvent slowly down the inside wall of the vial and swirl gently. Never shake. Our peptide calculator gives exact volumes.
How should nasal spray peptides be stored?
Refrigerate at 2–8°C and use within 28 days. Keep the bottle upright and away from light. All Peptides UK 4U products are strictly for in-vitro research use — not for human use.
Are these peptides legal to buy in the UK?
Yes — all peptides listed are legal to purchase and possess in the UK for laboratory research purposes. They are not licensed medicines and are supplied for in-vitro research only.
How is Melanotan 2 (MT-2) prepared as a nasal spray?
Our pre-filled MT-2 nasal spray is reconstituted at 10 mg in 10 ml sterile saline (1 mg/ml). A research reference table is shown on the MT-2 product page when the nasal spray format is selected, including approximate spray counts and frequency (daily for Weeks 1–8, then 1–2× per week for maintenance). Spray counts assume a 0.1 ml delivery per spray (~100 mcg per spray). This is for laboratory research reference only — not for human use.
How is PT-141 prepared as a nasal spray?
Our pre-filled PT-141 nasal spray is reconstituted at 10 mg in 10 ml sterile saline (1 mg/ml). A research reference table is shown on the PT-141 product page when the nasal spray format is selected, including approximate spray counts and frequency. Spray counts assume a 0.1 ml delivery per spray (~100 mcg per spray). This is for laboratory research reference only — not for human use.
