Fertilaid for men experience?

TtcMommyof1 • Wife to a wonderful man ❤️. Mommy to an amazing 6 year old girl 💕. Due 11/8 with a baby boy after 37m ttc💙
My husband had a SA in March and had a zero sperm count as a result of testosterone therapy that was prescribed to him. Our first daughter (now 4 years old) was conceived first month. He discontinued the testosterone and is just waiting for his body to get back to his normal production. His last treatment was in February, and we're trying to speed things up so I purchased fertilaid. Does anyone have any experience or success stories?! Thanks in advance!!
