----------|-------------------| | "Destroys all muscle" | Overstated; 20-40% lean loss, mitigable | | "Easiest cut ever" | Likely accurate for most users | | "Just discipline, bro" | Ignores biological regulation | | "Better than clen/DNP" | Correct — much safer profile | | "Works great with gear" | No data, but mechanistically plausible | | "Not for serious lifters" | Context-dependent; can work well |
The Bottom Line
The bodybuilding community's concerns about muscle loss are valid but often exaggerated. GLP-1s do cause some lean mass loss, but it's: - Similar to diet-induced loss - Substantially mitigated by training and nutrition - Potentially almost eliminated with future muscle-sparing combinations
For lifters with significant fat to lose, the tradeoff is often worthwhile. For those already lean, the calculus is less clear.
As with most things in fitness: context matters, individual response varies, and the best protocol is the one you'll actually follow.
