Even if your growth hormone spikes right after lifting weights, that doesn’t mean you’ll end up with bigger arms after 8 weeks of training.
Claim Language
Language Strength
association
Uses association language (linked to, correlated with)
The claim uses 'not associated with' and 'no significant correlation was observed', which explicitly frame the relationship as a lack of statistical link rather than causation or probability.

Effects of rest intervals and training loads on metabolic stress and muscle hypertrophy
Even though one group had a big spike in a growth hormone after working out, both groups ended up with bigger arms after 8 weeks — and the size of the hormone spike didn’t predict who got bigger. So the hormone spike doesn’t seem to matter for muscle growth.
