iNot medical advice. We don’t recommend any dose. Every dose below is a quote from the person named, describing their views or their own use. Oxytocin is an approved prescription medicine for labour and after childbirth, given by injection or infusion under medical supervision. Intranasal use for libido, training or mood is off-label and experimental.
3 statements from 1 person. Each one is word for word: we add punctuation only and mark cuts with […]. The chips repeat the exact words used.
“consider taking about 500 to 750 iuse oxytocin internally about 1 hour before your L day. Seems to have about a 2hour half life when taking internasal”
Context: Solo video. The captions read “iuse”, “internally” and “L day”; he appears to mean IU, intranasally and leg day. His 2026 figures are far lower (20–100 IU), so this line is flagged for a listen.
“My leg days became ultra pleasurable, a very positive association with training to failure on particular exercises and far beyond. So, my leg days were legendary after taking maybe 20, 40, sometimes 100 IUs oxytocin pre-workouts.”
Context: His own experience. He does not state the route here; in a 2021 video on the same topic he describes a nasal spray.
“20 IUs, 30 IUs, 50 IUs, whatever your sweet spot is, is sufficient. You can keep it at that dose, taken about an hour before sexual activity. But if you start to use it every day, you might end up with 200 IUs or 500 IUs, which is an insane dose. You might experience a little bit of flushing as a side effect of very high dosages of oxytocin. So, I'd use oxytocin intermittently.”
Context: Just before, he says “the dose highly depends on your tolerance” and that he and clients “noticed that you need to continuously bump up the dose”.
1 statement from 1 person about risks and how strong the evidence is.
“which unfortunately doesn't seem to be the case for myself and everybody that I've talked to: oxytocin nasal spray seems to be ineffective regarding sexual activity”
Context: In 2021 he found no libido effect; in his 2026 clip he says the opposite (that his libido became “problematic” on oxytocin combined with Semax).
Context, not a dosing guide. Intranasal oxytocin studies usually used about 24 IU, often once. Results have been mixed, and a large trial in autism found no benefit. These are evidence context, not a guide.
| Study | Studied in | What the study used | What it found |
|---|---|---|---|
| Kosfeld et al., 2005, NaturePubMed 15931222 | Healthy men, trust game | Single intranasal dose | Increased trust in social risk-taking |
| Striepens et al., 2013, Sci RepPubMed 24310737 | Healthy men | 24 IU intranasal | Raised oxytocin levels in blood and cerebrospinal fluid |
| Sikich et al., 2021, N Engl J MedPubMed 34644471 | 290 children and adolescents with autism (phase 2) | Intranasal, target 48 IU daily for 24 weeks | No difference from placebo in social or cognitive outcomes |
Yes, as an injection used in obstetrics. Intranasal use for other purposes is off-label.
His 2021 video says “500 to 750” and his 2026 clip says 20–100 IU. We quote both as captioned and have flagged the 2021 line for a listen.
It is debated. Striepens 2013 found raised CSF levels; Leng & Ludwig 2016 argue very little reaches the brain.
