What is CD38 and why is it considered an “NAD+ killer”?

?

CRP, WBC spikes, low-grade infections…

Balancing higher workload with injury prevention.

What actual gym performance changes to expect?

Real comparisons wanted.

Fasting glucose, A1C, fasting insulin.

CRP can spike if your body is dealing with inflammation from contamination but it’s not specific

More gear doesn’t mean more volume your joints and tendons still recover slow

Liver enzymes might rise if theres solvent or impurity irritation but again not proof

A lot of people actually gain more by training 4 days not 6–7.

Bloodwork can hint somethings wrong but it can’t say yep that vial was contaminated

If strength is flying keep sessions tight don’t let ego add junk volume

Dirty oils sometimes show up as localized reactions not blood markers.

If pumps get painful or back pumps hit that’s your sign volume is too high

Good rule add volume only when recovery is consistently excellent.
