Whether someone chooses a Luer Lock for its structure or a Slip Tip for its simplicity, the syringe should help foster confidence. The right choice is the one that makes the process feel steady and soothing. Understanding these emotional responses helps individuals choose the syringe that supports their sense of wellbeing. Those with softer hands or those who prefer a more rigid connection often appreciate the structure of the Luer Lock. Another person may begin with Luer Locks for reassurance but switch to Slip Tips once they become confident enough to prefer a softer feel. Most syringes include incremental hash marks between larger, numbered ones. Injection supply kits can be obtained at any Planned Parenthood of Michigan health center if you are prescribed injectable hormone medication by PPMI. If you need more information about purchasing injection supplies, this information may be helpful. The label may be on the box or packaging, or the medication vial itself. It is important to check this label each time you pick up a prescription as this volume you inject may change based on dose adjustments or based on changes in the concentration of medication prescribed. Pharmacy has me injecting Test C with 25 Gauge needles. I don't even really feel the 25G needles that I've been using, so I can only imagine how comfortable these little guys will be! Plus, they're Luer Lock needles, so I can still use a larger draw needle for easy filling! Let's face it, guys -- TRT is for life, and all those injections add up! It may be more difficult to draw up and inject using these smaller-volume tools, but you may be able to get a more precise dose. Syringes with volumes less than 1mL are usually insulin syringes. Someone who started with Slip Tips may later prefer the secure feel of a Luer Lock as their technique evolves. Others prefer the simplicity of the Slip Tip because it makes preparation feel calm and uncomplicated. Some individuals enjoy the firmness of the Luer Lock because it makes the entire process feel grounded and secure. Most patients using single-use testosterone vials will be instructed to inject a small amount of the volume in the vial (example 0.4 mL of a 1 mL vial); the remainder of the medication in the single-use vial should be discarded. Our injection kits contain 1" needles for injections, allowing them to be used for either IM or SC hormone injections. For IM injections, a 1-inch or 1.5-inch needle can be inserted completely (using the full length of the needle, to inject medication at a depth of 1–1.5 inches) for most bodies. We recommend using a larger/thicker needle (around 18–20 gauge) to draw up the medication more easily and a smaller/thinner needle (around 22–25 gauge) to reduce discomfort with injecting the medication. I got a box of 1ML luer lock syringes. I think that sacrificing a little injection speed for less scar tissue accumulation is well worth it in the long run, and these needles really fit the bill! Sure, we rotate injection sites and try to do as little damage as possible by injecting properly, but the thickness of the needles we use plays a large role in how much scar tissue we build up. A comfortable and reliable connection is essential for creating a calm and gentle injection ritual. The difference between Luer Lock and Slip Tip syringes for TRT is something many people do not fully understand when they first begin exploring testosterone therapy. The volume of medication prescribed accounts for "loss" in the syringe tip and needle. A 1-inch or ⅝-inch needle can be inserted through the skin and into the underlying fatty tissue for SC injections. The dose of injectable medication depends both on the concentration of the medication (amount of medication in a specific volume) and the volume of medication injected. When using injectable medications, it is important to ensure you are measuring/drawing-up the correct amount of medication. And inject with 29 gauge? I am certain that it would be capable of injecting oil even at such an extremely bent angle. I just got a box of BD 30G 1" needles, and I am super excited to try them out! I purchased them because I currently use 25G 1" pins (which are just fine), but I want to do all I can to minimize scar tissue.
