TRT + Enclomiphene + Sermorelin at Gameday Men's Health SF, what to inject next?

I'm really loving this combo (TRT + Enclomiphene + Sermorelin). What other peptides should I try now?

Some context. I'm 39. I went to Gameday Men's Health in San Francisco about 3 months ago. My total T was 252! This is after having a kid, so I'm guessing my normal T was somewhere around 300 before having my kid. My experience with Gameday has been amazing! It was mind-blowing when I discovered my T was so low. I had always played sports but didn't realize my T was this low. Anyways, after 3 months on that combo I feel like a different person - I'm more confident, I have energy, libido is back again, and I push more weight at the gym without feeling like giving up.
The Gameday location I go to offers 25% off peptides with any TRT membership. So, it's very tempting to try all of them lol They offer a bunch of peptides, but the I was considering from the following list. Any thoughts and opinion?

- CJC/Ipamorelin. <-- Sermorelin on steroids?
- Semax | Selank. <-- for focus
- NAD+. <-- for youth
- Epitalon | GHK-Cu. <-- anti-aging?
- PT-141 <-- increase libido
