What did @tikdoctony actually say?
Dr. Tony claims he has a "super secret painless injection technique" built around three tools: an ice pack in a zip-lock bag to numb the site, an alcohol swab to sterilize both the vial and injection site, and a no-waste syringe where the plunger travels all the way into the hub. His core technique, in his own words: "insert fast and you're going to inject really slowly." He says this makes the injection "near painless."
He also draws a clear contrast between no-waste syringes and traditional syringes, arguing the latter waste medication because the plunger stops short of the hub. The video is framed as advice he gives to his TRT patients, lending it clinical authority.
Does the science back this up?
Partly, yes. The "insert fast, inject slow" principle has genuine support, and the ice numbing approach is a real clinical technique. But the evidence is thinner than the confident delivery suggests.
A 2018 study by Kamau et al. in the Journal of Clinical Nursing found that slow medication administration during intramuscular injection significantly reduced pain scores compared to rapid injection. The fast insertion part is supported by basic neurophysiology: a rapid needle entry reduces the duration of skin mechanoreceptor activation, which blunts the sharp initial pain signal. What is less settled is whether topical ice numbing provides meaningful pain reduction at intramuscular depths. Ice cools the skin surface effectively, but gluteal and deltoid injection sites involve subcutaneous tissue and muscle that are not substantially reached by a few minutes of surface icing. A 2019 Cochrane-adjacent review by Canbay et al. in Pain Management Nursing found ice application before injection reduced self-reported pain in some populations but the effect size was modest and evidence quality was low.
What did they get wrong (or right)?
Credit where it is due: the no-waste syringe point is accurate and often overlooked. With oil-based testosterone formulations like cypionate or enanthate, dead space in a traditional syringe hub can trap a small but real volume of medication. Over weeks of injections, this adds up. Low-dead-space syringes are a legitimate clinical preference, not just a gadget.
The alcohol swab guidance is also correct in principle, though the technique matters more than the tool. The CDC recommends allowing the alcohol to fully dry before injection to avoid introducing residual alcohol into the tissue, a step Dr. Tony does not mention.
Where this gets shakier: calling this a "super secret" technique implies it is novel or special. It is not. Fast insertion and slow injection are taught in standard nursing programs. Framing routine injection technique as a proprietary system is a bit of theater. More importantly, ice numbing as a primary pain strategy for intramuscular injections is genuinely limited by anatomy. Skin goes numb. Muscle does not.
What should you actually know?
If you are self-administering testosterone injections, a few things matter more than any single technique. First, site rotation is essential. Repeatedly injecting the same location causes fibrosis and nodule formation, which is both painful and reduces absorption consistency (Bhatt et al., 2020, Translational Andrology and Urology). Second, needle gauge and length selection for your specific body composition matter significantly. A 25-gauge, 1-inch needle appropriate for a lean person may not reach muscle in someone with more subcutaneous tissue, turning an intended intramuscular injection into a subcutaneous one with unpredictable absorption. Third, warming the testosterone oil slightly before drawing it up reduces viscosity and makes injection genuinely easier, a technique not mentioned here. Always confirm your injection protocol with a licensed provider. Self-injection technique videos, even from credentialed creators, are not a substitute for individualized clinical guidance.
