Calling it significantly cheaper feels like a bit much. Bulk Tirz runs about $.20/mg for 1200mg, while Reta comes in near $.48/mg.
At the top doses that have been published from trials, that works out to only $2.76/week more, if you're stocking up to lock in the best rate. For me, $2.76/week is a fair trade to hold onto roughly 6-10lb of lean mass across an 80lb cut, since GCGR helps spare lean tissue and gives steadier energy for lifting.
Even if the scale lands on the same number either way, on Tirz I'd be carrying 6-10lb more fat at that weight than I would on Reta, plus all the time it would take to rebuild that lean fiber.
Anecdotal note on energy for sticking with training:
Day 1 on Reta (no prior meaningful exposure) my exercising walking heart rate averaged 114bpm, while the day before and the day after both averaged 115bmp.
18 days in, doing the same exercise with more incline and less perceived effort, my average heart rate over the last 3 days sits around ~130bmp, with reta at 6-9.2mg (Tirz tapering from 2.5mg down to ~1.7mg).
Tirz never gave me any trouble, and so far I have zero regrets about moving to reta.
