Training on 10mg — is it realistic

Started reta 9 weeks ago. Training intensity is noticeably down at 8mg, worried 10mg will end my lifting window.

Lifting 4x/week, mid-to-high volume, avg 75 min sessions. At 8mg I'm hitting sessions but feeling gassed around minute 50 that I wouldn't have felt at baseline. Heart rate is higher at comparable loads. Recovery between sets is longer.

Anyone hold lifting intensity at 10+mg or does it just become impossible?

Hitting sessions at 10mg but I dropped one session per week and cut volume 20%. The cardiovascular cost is real. Intensity (load) is holdable, total work output is not.

Pragmatic answer — periodize. Lifting season runs on 6mg max. Loss-maximization phase runs on 10mg for 8 weeks, training becomes maintenance-only. Don't try to do both at max effort.

Intra-workout carbs help more than you'd think on reta. 40g cyclic dextrin starts to bring the gas tank back at minute 40.

@macrosguru trying this Friday. Hadn't considered intra-workout because appetite is so blunted but that's separable from substrate availability.

Hold intensity, drop volume. That's the move. You're not losing strength at 10mg, you're losing work capacity, which is different. I ran 10 for 12 weeks last year doing 3x/week heavy comp lifts plus 2x/week moderate accessory and it worked fine. The guys trying to maintain their full 4x/week 75 min routine are fighting the drug instead of respecting what it does to your cardiovascular system. Your HR is elevated because reta is literally making your metabolism run hotter. Work with that, not against it.
