Kilimanjaro vs Retatrutide – Honest Comparison
Posted: Mon Sep 15, 2025 4:05 am
I’ve been following the whole GLP-1 weight loss pen trend for a while and finally decided to try both Kilimanjaro (tirzepatide) and Retatrutide. I sourced mine from sveltalabs.com
since they ship with next day refrigerated delivery in the UK.
Here’s my personal take:
Kilimanjaro 40mg injection: strong appetite suppression, but I did notice more bloating and stomach discomfort the first couple of weeks.
Retatrutide 40mg pen: felt “cleaner” to me, more steady energy, and I had noticeably less food noise in my head.
From what I’ve read, Kilimanjaro is a dual agonist (GLP-1 + GIP), while Retatrutide is a triple agonist (GLP-1, GIP + glucagon). That could explain why Retatrutide seems to push fat metabolism further.
Both work — but Retatrutide really feels like the next generation.
