- 1:5022-hour IV infusion studyHe cites a study in healthy men where LH rose as high as threefold and testosterone increased significantly. He says this shows the system can be activated under controlled conditions.
- 2:25Subcutaneous injections fall shortBurud says most people inject under the skin, not by IV, and that results for raising testosterone are much less impressive. He says an LH rise does not always lead to lasting testosterone gains.
- 3:09Desensitization riskHe warns that frequent use may make receptors less responsive. In his words, the system can become numb.

What the video says
Dr. Sajid Burud opens by asking whether kisspeptin-10 is a natural way to raise testosterone or mostly hype. He says at the start that substances like this are largely experimental and not FDA-approved for this use, and he describes them as research compounds in this context. His answer to the headline question is that it is neither a simple yes nor a simple no.
He explains kisspeptin as a peptide made in the hypothalamus that acts as a gatekeeper of the reproductive hormone system. He compares testosterone replacement therapy to pushing a stalled car and kisspeptin to the key that starts the engine. He then walks through the chain he calls the body's hormonal chain of command: kisspeptin prompts GnRH release, GnRH prompts the pituitary to release LH, and LH signals the testes to produce testosterone. On paper, he says, more kisspeptin signaling should mean more testosterone.
On evidence, Burud points to a study in which healthy men received a 22-hour IV infusion of kisspeptin-10. He says LH rose as much as threefold and testosterone increased significantly, so the system can be activated under controlled conditions. He then says most people use subcutaneous injections instead, and that the data for that route is much less impressive. In his telling, a shot may raise LH without producing a lasting rise in testosterone. He also raises desensitization, the possibility that receptors become less responsive if kisspeptin is used too often.
Burud suggests its most promising role may be in men with secondary hypogonadism, where he says the testes can work but the brain signal is weak. He also floats the idea of using it alongside TRT, comparing the concept to how hCG is used, and he stresses that medical guidance matters. He mentions a trial in which, he says, kisspeptin raised activity in sexual brain pathways and improved penile rigidity by as much as 56% compared with placebo. He closes by saying no peptide replaces sleep, diet, stress control and metabolic health, and calls kisspeptin-10 a niche tool with potential in the right context.
On each compound
Kisspeptin-100:40
Burud says kisspeptin-10 raised LH and testosterone in a 22-hour IV study in healthy men, but that subcutaneous injections give much less reliable testosterone results. He describes it as a niche tool, mentions desensitization as a concern, and notes it is not FDA-approved for this use.
See how your DNA reads Kisspeptin-10What this video doesn’t settle
- The video names the 22-hour IV study and the libido trial but gives no authors, sample sizes or sources, so the reader cannot check them.
- Burud says subcutaneous results are less impressive but shows no data, doses or dosing schedules for that route.
- The idea of using kisspeptin alongside TRT is offered as a possibility by Burud, and no data on it is presented.
Questions this video answers
Does kisspeptin-10 increase testosterone?
Burud says yes, but only in a limited sense. He cites a 22-hour IV study in which LH rose as high as threefold and testosterone increased significantly. He says results from subcutaneous injections are much less reliable.
Is kisspeptin-10 FDA approved?
Burud says kisspeptin-10 is not FDA-approved for this use and that peptides like it are generally considered research compounds in this context.
Why might kisspeptin-10 stop working over time?
Burud raises desensitization. He says that if it is used too frequently, receptors may become less responsive and the signal may become less effective.
Who does Burud think kisspeptin-10 might be for?
He suggests it may be most relevant for men with secondary hypogonadism, and possibly for men on TRT, comparing that idea to how hCG is used. He says medical guidance matters in either case.
What does the video say about kisspeptin-10 and libido?
Burud cites a trial in which kisspeptin increased activity in sexual brain pathways and improved penile rigidity by as much as 56% compared with placebo. He presents this as newer research suggesting effects beyond hormone numbers.
