@surgicalknowledge11's IM injection technique, fact-checked
Quick answer
The video teaches dorsogluteal IM injection using the upper outer quadrant landmark to avoid sciatic nerve injury, a technique that was standard teaching but has been largely replaced in clinical guidelines by the ventrogluteal approach. For peptide therapy administered intramuscularly, correct site selection and technique are relevant safety considerations, though many peptides used in optimization contexts are administered subcutaneously rather than intramuscularly. Patients self-administering any injectable compound should receive site-specific training from a qualified healthcare provider, not derive technique from social media content alone.
Our take · Written by FormBlends editorial team · Reviewed by FormBlends Medical Team· This is not a transcript. It is our independent review of the video above.
What did @surgicalknowledge11 actually say?
The creator walks through intramuscular injection technique, focusing on site selection in what appears to be the gluteal region. The key clinical instruction is to use the "outer quadrant" and specifically the "upper outer quadrant" of the buttock to avoid what they call the "Shiatic nurse or blood vessel" — an apparent phonetic reference to the sciatic nerve. The video blends Urdu/Hindi with English, making some specific claims difficult to verify word for word, but the anatomical intent is clear enough to evaluate.
The core message: when giving an IM injection in the gluteal area, aim for the upper outer quadrant to stay away from the sciatic nerve and nearby vasculature. That is the claim worth checking.
Does the science back this up?
Partially, yes, but this advice is outdated by about two decades of nursing and injection safety literature. The upper outer quadrant rule was the standard teaching for most of the 20th century, but it has real problems that the video does not mention.
The dorsogluteal site, which is what the upper outer quadrant approach typically targets, carries a documented risk of inadvertent sciatic nerve injury, even when the quadrant rule is followed correctly. A 2009 review by Nicoll and Hesby in the Journal of Continuing Education in Nursing found that the dorsogluteal site is associated with higher complication rates compared to the ventrogluteal site and called for a shift in clinical practice. The ventrogluteal site, located over the gluteus medius and minimus rather than the gluteus maximus, is now the preferred IM site in most updated clinical guidelines precisely because the sciatic nerve and superior gluteal vessels are not in the vicinity. The World Health Organization and multiple nursing bodies have updated their guidance accordingly.
What did they get wrong (or right)?
Credit first: the instinct to avoid the sciatic nerve is correct. Sciatic nerve injury from IM injection is a real, documented complication. A 1999 case series by Mishra and Stringer in the Developmental Medicine and Child Neurology journal documented nerve palsy cases tied to incorrectly placed gluteal injections, particularly in pediatric patients. Mentioning the sciatic nerve at all puts this creator ahead of videos that skip anatomical warnings entirely.
What they got wrong: recommending the upper outer quadrant as the primary go-to site without noting that contemporary evidence favors the ventrogluteal site. Teaching the quadrant rule alone gives learners false confidence. The sciatic nerve's course is variable between individuals, and the "safe zone" defined by the quadrant method is less reliable than it looks on a diagram. If someone is injecting peptides like BPC-157 or TB-500 subcutaneously or intramuscularly based on this guidance alone, they are working with incomplete information.
What should you actually know?
The ventrogluteal site is the current evidence-based first choice for gluteal IM injections in adults. You locate it by placing the heel of your hand on the greater trochanter, pointing your index finger toward the anterior superior iliac spine, and spreading your middle finger toward the iliac crest. The injection goes into the V formed between those two fingers. This area does not have major nerves or vessels running through it, which is why Greenway's 2004 review in the British Journal of Nursing recommended it as the default site.
For people self-administering peptide therapies, the practical reality is that subcutaneous injection is more commonly used and technically simpler than IM for many compounds. IM technique matters when it is genuinely indicated, but learning it from a short TikTok with partial audio clarity is not a substitute for hands-on training. Needle length, injection angle, aspiration debate, and post-injection monitoring are all real variables this video does not cover.
- Always confirm with a licensed provider which route of administration is appropriate for your specific compound and health situation.
- Site rotation matters for tissue health regardless of which IM or subcutaneous site you use.
- If you feel sharp radiating pain during an injection, stop immediately. That is a nerve warning sign.

FormBlends verdict
The video teaches dorsogluteal IM injection using the upper outer quadrant landmark to avoid sciatic nerve injury, a technique that was standard teaching but has been largely replaced in clinical guidelines by the ventrogluteal approach. For peptide therapy administered intramuscularly, correct site selection and technique are relevant safety considerations, though many peptides used in optimization contexts are administered subcutaneously rather than intramuscularly. Patients self-administering any injectable compound should receive site-specific training from a qualified healthcare provider, not derive technique from social media content alone.

What it helps with
- The video teaches dorsogluteal IM injection using the upper outer quadrant landmark to avoid sciatic nerve injury, a technique that was standard teaching but has been largely replaced in clinical guidelines by the ventrogluteal approach. For peptide therapy administered intramuscularly, correct site selection and technique are relevant safety considerations, though many peptides used in optimization contexts are administered subcutaneously rather than intramuscularly. Patients self-administering any injectable compound should receive site-specific training from a qualified healthcare provider, not derive technique from social media content alone.
- The ventrogluteal site, not the dorsogluteal quadrant, is the evidence-based preferred IM injection site per Nicoll and Hesby (2009, Journal of Continuing Education in Nursing) due to lower nerve and vessel proximity.
- Sciatic nerve injury from IM injection is a real complication: Mishra and Stringer (1999) documented cases resulting in nerve palsy from incorrectly placed gluteal injections.
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- Compound access, legal status, and product quality still need a separate safety check.
- Social video captions rarely show the full evidence base behind a claim.
Best next step
Compare the claim against a FormBlends guide, safety page, and licensed-provider review before acting.

- The ventrogluteal site, not the dorsogluteal quadrant, is the evidence-based preferred IM injection site per Nicoll and Hesby (2009, Journal of Continuing Education in Nursing) due to lower nerve and vessel proximity.
- Sciatic nerve injury from IM injection is a real complication: Mishra and Stringer (1999) documented cases resulting in nerve palsy from incorrectly placed gluteal injections.
- The upper outer quadrant rule is not wrong per se, but it creates a false sense of safety. The sciatic nerve's anatomical path varies between individuals, making the quadrant boundary less reliable than it appears in textbook diagrams.
- Most peptide compounds used in recovery and optimization contexts, including BPC-157 and TB-500, are typically administered subcutaneously rather than intramuscularly. Confirm the correct route with your prescribing provider before injecting.
- Needle length selection for IM injection must account for individual body composition. A one-size approach is not supported by current injection safety data from the CDC's 2021 updated guidelines.
- Any sharp, radiating, or burning pain during an IM injection suggests possible nerve contact. Stop immediately and withdraw the needle. This is not a normal sensation.
- Short-form social media is not a substitute for hands-on injection training. Technique errors that look minor on screen can cause real injury, including hematoma, nerve damage, or abscess formation.
