Fear of needles holding you back from peptides? There’s an alternative and I use it myself!
The Comfort-In Needle-Free Injection System

The Comfort-In injector uses a fluid needle. The device converts injection fluid into a micro-thin jet that penetrates the skin at high velocity. Unlike needles which inject fluid into a blob, the Comfort-In disperses the injection in a cone-like shape, which allows for faster absorption.

Benefits of the Comfort-In

Besides the obvious, going needle-free offers significant benefits:

• Makes peptides possible for needlephobics: My anxiety with needles is extreme! I can’t even LOOK at a needle penetrating skin! I simply can’t get myself to do it. I would not be realizing the life-changing benefits of peptides without my Comfort-In injector!

• Minimal pain and tissue trauma: While not always 100% sensation-free, the Comfort-In is generally much less painful than a needle. Sometimes, the only proof I have that the peptide was injected is the empty injection nozzle! Because the fluid jet is so thin, it causes less damage to the skin and underlying tissue, reducing the risk of developing lumps and scar tissue formation over time. This is especially significant for peptides protocols that call for daily, sometimes twice daily, injections.

• No Needlestick Injuries: The risk of accidental punctures is gone completely for you and for anyone else who might use the Comfort-In to inject someone else.

• Reduced Infection Risk: Without the “sharp”, the chances of cross-contamination are minimized and medical waste disposal is simplified.

• Improved Bioavailability: The “cone-shaped” dispersion pattern created by the Comfort-In injector increases the surface area of the injection fluid in contact with the tissue. This leads to faster absorption and more consistent peak levels of the injection in the bloodstream.

• Ease of Self-Administration: The Comfort-In injector is so easy to use, most people will feel comfortable using it with their non-dominant hand. This makes it easy to rotate injection sites on both sides of the body, even in the buttocks!

• Customer Service: Got a question? The owner/inventor of the Comfort-In injector accepts WhatsApp calls! Don’t be surprised if he calls you with a question about your order. He might call you late—He’s in Australia!

Be Aware

The Comfort-In is not without limitations. In the interest of full disclosure:

• It’s a bit pricey: The starter subcutaneous kit will cost a little over $300 and ships from Australia. You’ll have to continue to buy consumables that cost more than syringes. Boxes of 50-each injection nozzles and vial adapters will add about $140 for both. I have to make the point that, for me, without the Comfort-In, I could not be using peptides at all! Without it, I would still weigh 225lbs!

• The Luer lock has more than the usual limits: The system does have a Luer lock adapter. You can always expect some fluid loss using any Luer lock but the Comfort-In’s Luer adapter adds one more point for loss. It can use be used for large doses but doesn’t make sense for small doses.

• One-size vial adapter: There’s only one size of vial adapter—14mm for 3mL vials. There are workarounds. The Luer lock adapter works as you might expect for large doses you usually take from 5mL vials, such as 50mg doses of NAD+. The amount of loss you’ll expect is less consequential when the dosage is so large. Conversely, with a little practice, the Comfort-In injection nozzle can be back-filled for dosages of 10 units or less. You’ll need to use a syringe but you’ll need to have needles on hand for reconstitution anyway! Added bonus: both of these methods will save you on consumables use.

• One-size nozzle: The nozzle capacity is 50 units. If you can’t work the reconstitution math to a max dose of 50 units or under, you’ll have to do two injections. Interestingly, you’ll feel the pressure of the injection LESS when it’s higher. I thought the max pressure would feel like blowing a hole into my skin but NO! I feel it more at the lower pressures. Makes sense when you think about it!

• Can’t control injection speed: For some peptides that sting, it’s recommended to inject slowly to ease pain. Since the Comfort-In works by injection pressure and speed, you can’t control that. For those “sting-y” peptides, add more BAC water or break up the dose into smaller-volume injections. Have a frozen gel pack ready!

• Learning Curve: Like using anything unique and novel, you’ll deal with a bit of a learning curve. How hard to press the injector into your skin? What spots tends to bruise? Practice with saline to get the hang of filling the nozzle by drawing from a vial with an adapter, backfilling nozzles with small doses, or drawing from a vial with the Luer lock adapter.
