stalled for 10 weeks at 0.5mg and I refuse to panic this time

Baseline Well Actually ×5

I have had 8 orders now and I keep a table, so here is the honest summary rather than a vibe.

Material has been consistent. Communication has not. Shipping has varied by about 36 days on nominally the same lane, which matters more in summer than in February.

The independent number came back 96.8% against a claimed 97.2%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.

Batch number is in the comments. Ask if you want the method.

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

the 20 month ALT check is the routine

Ferritin tanked from 6 to 23. Small appetite, reduced iron intake, nobody was testing it until I asked.

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

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

The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.

Removed a chain here. The rule is one line long and it is not negotiable.

Not convinced. The evidence does not support that reading.

What are your reference ranges?

u/lina_almeida6 points·2 months ago

Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.

u/britt_marchand3 points·2 months ago

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

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

HOMA-IR is crude but free and useful for tracking

About c/bloodwork

What to measure before you start, what to re-measure, and how to interpret movement without panicking. ApoB over LDL-C, HOMA-IR as a crude free tool, ALT and the fatty-liver story, eGFR noise during rapid loss, and the deficiencies that a 1,100-calorie appetite will hand you.
