PT-141 + Oxytocin Nasal Spray
A prescription nasal spray that pairs two peptides studied for different sides of intimacy. You use it only when you need it, about 45 minutes to 2 hours before planned intimacy.
Check your blood pressure first and gently clear your nose. Insert the nozzle into one nostril and give 1 spray, then lie down right away for several minutes. Prime a new bottle before its very first use by pumping into the air until a fine mist appears.
Only if needed, and at least 3 hours after your first spray, in the other nostril. Never use more than 2 sprays in 24 hours or more than 12 sprays in a month.
Each spray (0.1 mL) delivers 0.3 mg PT-141 and 60 units of oxytocin. The 5 mL bottle holds 15 mg PT-141 and 3,000 units oxytocin, about 50 sprays. At the monthly maximum of 12 sprays, one bottle lasts about 4 months, as long as it is used by the date on the label.
Nausea is the most common, especially the first time or after a second spray. It usually fades within a couple of hours, and staying hydrated helps. Some people notice flushing or warmth, a mild headache, nasal irritation, dizziness, or a brief rise in blood pressure that settles within a few hours. With repeated use, some people notice darkening of the skin or gums; tell your provider if you see this.
Do not use this spray if your blood pressure is high or uncontrolled, if you have heart disease, or if you are pregnant, could be pregnant, or are breastfeeding. Seek care right away for chest pain, a severe or lasting headache, fainting, a very high blood pressure reading, or any sign of an allergic reaction.
Keep it in the refrigerator between 36°F and 46°F (2 to 8°C), standing upright and away from light and heat. Do not freeze it, and never use it past the date printed by the pharmacy. Keep it out of reach of children.
Yes. Every order is reviewed by a licensed provider before it ships, and the spray is prepared by a Licensed Compounding Pharmacy. If your provider determines it isn’t appropriate for you, your order is refunded.

What’s Inside
Two peptides that may support both the physical and emotional sides of intimacy, in a nasal spray you use only when you need it.
A peptide that acts on the brain’s MC4 receptor pathways rather than on blood flow, studied for its role in desire and sexual response. Each spray delivers 0.3 mg.
0.3 mg · Desire · ArousalOften called the bonding hormone, oxytocin may support closeness, trust, and emotional connection. Each spray delivers 60 units, pairing the emotional side of intimacy with the physical.
60 Units · Closeness · ConnectionOne spray in one nostril, 45 minutes to 2 hours before planned intimacy. Absorbed through the lining of the nose, with no needles and no mixing.
No Needles · About 50 Sprays · As NeededPrescribed after licensed provider review and prepared by a Licensed Compounding Pharmacy. Shipped cold and stored in the refrigerator to keep it fresh.

The Science
PT-141 and oxytocin work through different pathways, one on arousal and one on connection, delivered through the nose for fast, needle free use.
One spray in one nostril, then lie down for several minutes. The lining of the nose is rich in blood vessels, so the peptides begin absorbing without swallowing or digestion.
Lie Down Right AfterPT-141 acts centrally on MC4 receptor pathways linked to arousal, which is a different approach than products that work on blood flow alone.
Central MC4 PathwaysOxytocin is associated with trust, bonding, and emotional closeness, supporting the connection side of intimacy alongside PT-141.
Bonding & ClosenessUse it 45 minutes to 2 hours before planned intimacy. A second spray is only for if needed, at least 3 hours later, up to 2 sprays a day and 12 a month.

Important — read before opening
Your spray ships in two parts. Take 60 seconds to assemble before first use.
Check Your Package Contents
Your nasal spray ships in two parts: the bottle and the pump mechanism. Both are inside the box, protected by the inner packaging. Do not discard anything until you have located both pieces.
⚠️ Do not throw away any packaging until you have fully assembled your spray.
Remove the Protective Cap From the Pump
Locate the pump mechanism inside the box. It will have a small protective cap covering the nozzle tip. Remove it and set it aside — you will reuse it to seal the spray between doses.
Attach the Pump to the Bottle
Insert the pump stem into the top of the bottle and press down firmly until it clicks into place and sits flush with the bottle neck. The pump should feel secure and not wobble.
Prime Before First Use
Hold the bottle upright and depress the pump 3 to 5 times until a fine mist appears. This purges any air from the stem. Your spray is now ready to use.
⚠️ Prime into a tissue — not toward yourself or others.
Replace the Cap and Refrigerate
After each use, replace the protective cap over the nozzle. Refrigeration is required. Store upright in your refrigerator away from strong odors. Do not freeze.
Recommended Usage
Use only as directed by your prescribing physician. Most protocols call for 1 to 2 sprays per nostril once daily. Do not exceed the recommended dose without consulting your provider.
If anything appears to be missing from your order, do not discard the packaging. Contact support@lavimd.com and we will make it right.
