HDL is tough to raise on its own. Endurance athletes get high HDL from lots of cardio. Omega-3 won't do much. I got great results combining 25 minutes daily cardio with proper eating. It matters more to check your LDL/HDL ratio than individual numbers.
I switched to weekly weigh-ins instead of obsessing daily - the mood swings from ups and downs were getting rough. Really helps to see the overall trend instead of freaking out over normal fluctuations. You're down 20 more, that's solid progress.
GHK-Cu timing isn't critical, read morning or evening both work. Sermorelin different - take evening before bed. Causes hormone surge and naturally happens after sleep so aligns with your body's rhythm.
