We’d been trying for 2 years. My count was 6 million/ml and the urologist wanted IVF. I came off my TRT and ran kisspeptin for 3 months on my own. Retested at 21 million. Wife is 9 weeks

Off-Ramp Fertility

I am a 44yr old man, i have been taking Kisspeptin every night for a few weeks now and I can categorically say that i didn't shoot loads half as big as i am shooting now when i was 18. It's a real shame I'm single and nobody else will get to see it, i really need to lose more weight and get some.
