Honestly I wouldn’t jump to adding more peptides here. That level of fatigue is a signal, not a gap to fill with another compound....
After ~30 lbs in 2 months, there’s a decent chance you’re in a pretty aggressive calorie deficit.
Adding peptides to “fix” fatigue from this is the wrong lever.
Stacking things like fat burners or energy peptides on top of a drug that’s already suppressing intake can just dig the hole deeper. It might mask symptoms temporarily, but it doesn’t fix the root issue.
I’d focus on getting calories, protein, hydration, and electrolytes VERY dialed in FIRST. If you restart, consider a lower dose and go SLOWER, making sure you're always focusing in the foundation vs huge calorie deficits .... most people feel a lot better doing that and it makes things sustainable.
