Different kinds of injections
First off, the syringe and needle you will need depend on the steroid you will inject, your dosage, and how you will inject (into which muscle group). There are three types of injections: intramuscular (IM), subcutaneous (SC), and intravenous (IV).
Intramuscular Injections
Intramuscular injections are the most common type of injection. For IM injections, you will need a syringe with a long, thin needle. The needle should be at least 1-1.5 inches long. This type of injection is best for steroids that are dissolved in oil, such as Depo-Testosterone and Winstrol Depot.
Needles
For intramuscular injections, choose a 1 inch, 23 gauge to 26 gauge needle. These needles are relatively thick and short but still sharp enough to pierce through the skin well. They are also usually hollow-pointed to allow for the steroid solution to pass through more easily.
Syringe Sizes
Once you know what type of injection you will be doing and what size needle you will need, it’s time to pick out a syringe in the corresponding size range. A common syringe in each size range is listed below.
Conclusion and summary
When buying injectable steroids, you should also keep in mind that you will also be buying syringes and needles.
