What are Needle-free Injections
and How do they Work?

Your research brought you here because you are sick of prodding yourself with needles just to get your, insulin, Testosterone, B12 or any other medication. Whether you’re a kid or a tough guy, nobody likes needles. Some people really don’t like needles, to the point where it interferes with their treatment.

Needle-free injections, also called Needle-Less injections, are simply an injection without needles. A needle-free injection occurs when the injectable medicine (eg. insulin, hormones, local anaesthesia and more) is pushed into the body through the skin, using a combination of pressure, high velocity and a syringe/nozzle that has been specially designed for this purpose. “The liquid becomes the needle”.

How to select the right injector? 

1Is your medication intended to be deposited into your muscles (intramuscular) or into your fatty tissue (subcutaneous)?
Is your medication intended to be deposited into your muscles, that means intramuscular or into your fatty tissue that means subcutaneous? One way is to ask your doctor or read the instructions on the medications pamphlet or labels, it should be in bold letters: “FOR SUBCUTANEOUS DELIVERY“ or “FOR (IM) INTRAMUSCULAR DELIVERY.” This means the following: Injection sites should be identified as Intramuscular or subcutaneous.
2What types of Comfort-in™ injectors do we have?
We carry three types of injectors, they all look the same but the difference is in the strength of the spring inside. Injector labeled “IM” intramuscular is tested and certified for Needle-less delivery of vaccines and other prescription liquid substances labeled “intramuscular delivery“. Most popular injector labeled “NORMAL” is certified and suitable for subcutaneous delivery of liquid medications intended for subcutaneous delivery such as Insulin. it’s ideal for delivery of local anaesthesia solutions anywhere the body. Injector Labeled “Soft” is currently used and suitable for delivery of local anaesthesia in the oral cavity in the dental application and is also used by cosmetic doctors for facial injections.
3How to inject correctly Oily based medication such as Estrogen/Oestrogen & Testosterone?
Oily based medication is usually injected into a muscle, in recent years doctors have been recommending “MICRO DOSING “ testosterone subconsciously into the fatty tissue. From customer’s experience the feedback is that the injector labeled IM with 6000 PSI is the best choice for oily based liquid medication delivery because it is 50% stronger than the injector labeled NORMAL 4000 PSI, therefore it will deliver. *It is recommended to inject 0.25ml at a time, therefore if you want to inject 1ml break it over 4 deliveries of 0.25ml each.
