What is the consensus on CJC + Ipamorelin timing?

Trying to understand whether morning vs night dosing actually changes anything in practice.

Reading conflicting takes everywhere. Some people swear by pre-bed dosing to ride the natural GH pulse, others say it doesn't really matter as long as it's away from meals.

Specifically curious about: (1) does dosing 2–3 hours after last meal actually matter, or is 60 minutes fine? (2) Does pre-bed vs morning meaningfully change outcomes for sleep, recovery, or body comp over a 10–12 week cycle? (3) Anyone tracked it both ways on themselves and noticed a real difference?

Not looking for protocol prescriptions — just trying to separate what's evidence-informed from what's lore that got repeated until it became 'consensus.'

Honest answer: the 'must be 3 hours post-meal' rule is overstated for most people. The mechanism is real (insulin blunts GH release) but the difference between 60 and 180 minutes is small unless you just ate a high-carb meal.

Pre-bed makes sense theoretically (stacks with natural pulse). In practice, the bigger variable is consistency. People who actually dose every day at any time beat people who do 'perfect' timing 4 days a week.

I ran morning for one cycle, pre-bed for the next. Honest answer: I couldn't reliably tell a difference in recovery or body comp. Sleep felt slightly deeper on pre-bed, but n=1.

Agree with @meridian_r. Consistency >> perfection. Pick a time you'll actually stick to.
