stalled for 13 weeks at 2.4mg and I refuse to panic this time

Baseline Sourced ×3 Long Haul ×2

Long-ish post, sorry. tl;dr at the bottom.

I have been tracking eGFR against triglycerides for 21 weeks because I could not find anyone who had. The correlation is weaker than I expected, which is itself mildly interesting given how confidently people link the two in here.

Caveats up front: one person, one lab, one assay, no control, and I changed my training in the middle of it, which was stupid.

tl;dr: probably real, definitely smaller than the threads imply, and not worth reorganising your week around.

eGFR noise on rapid loss is real. 5 week noise, 20 week trend. Do not panic at week 65.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

baseline is the most important ferritin measurement, you cannot collect it later

Strongly agree. ALT is where you catch the liver story early.

A1c moves slowly, quarterly is plenty

ApoB from 21 to 31 is movement, not noise

Yes, exactly this, and it is the bit that took me 4 weeks to accept.

Yeah, baseline matters more than any later number.

Respectfully this is a sample of one presented as a finding.

Retitled to remove editorialising. Put the evidence in the body.

Retitled to remove editorialising.

Adding to this: ALT is doing more work than the comment implies.

HOMA-IR is crude but free and useful for tracking

That is net peptide content, not purity. Different number, different meaning.

This is the "correlation is mechanism" thing again. You changed three variables at once.

Disagree. What you are describing is consistent with bloodwork, not with what you concluded.
