no "is this good?" without saying what the compound and claimed purity are

redact your own name, not the vendor's batch details

Asked WXT for the batch-specific COA and they sent it within six hours, full document, batch number, date, everything. That is the baseline.

comment on [PSA] Medutest is not what most of this community thinks it is in c/vendorvetting · 15 points · 6 months ago

Slight fix: the number was 98.7, not 98.9. Decimal point, but a fairly consequential one.

comment on week 51 check-in — 11kg down, the food-noise thing manageable, one thing confusing me in c/vendorvetting · 2 points · 6 months ago

Did you test the vial you received or are we going off the vendor COA?

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

text only is the whole point of the community

comment on [Discussion] can we stop arguing about bacteriostatic water until somebody posts a number in c/reconstitution · 3 points · 7 months ago

dosing errors come from people reconstituting two vials differently and forgetting which is which

Yes, exactly this, and it is the bit that took me 38 weeks to accept.

comment on timeframe: what the trials say vs what this community says in c/progresspics · 6 points · 7 months ago

Disagree. What you are describing is consistent with non-scale victory, not with what you concluded.

comment on [Question] milestone — what am I missing here in c/progresspics · 0 points · 8 months ago

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

comment on three years of dead space threads, summarised so you do not have to read them in c/reconstitution · 27 points · 8 months ago

Sceptical. If this were true we would see it reflected in the data and we do not.

comment on week 56 check-in — 12kg down, injection-site soreness manageable, one thing confusing me in c/coa · 28 points · 9 months ago

This is the correct framing. The COA structure matters as much as the number.

permalink

comment on [Question] how do you actually verify reconstitution in c/reconstitution · 1 points · 9 months ago

never post a calculation as advice without stating the concentration

comment on what changed for me between week 45 and week 88 in c/coa · 154 points · 9 months ago

no "is this good?" without saying what the compound and claimed purity are

comment on [Results] 82 weeks, 15kg, and progress was the hard part in c/progresspics · 16 points · 9 months ago

Did anything else change in the same window?

comment on why does nobody talk about dead space in c/reconstitution · 50 points · 10 months ago

Cosigning. The concentration on the vial in marker is load-bearing.

comment on [PSA] order records is not what most of this community thinks it is in c/vendorvetting · 12 points · 10 months ago

GL Biochem three times. First two perfect, third arrived with a gel pack failure. Powder tested 95.1% anyway, so no harm done.

positive and negative reports both need the same evidence standard
