comment on Spain: batch, and what it actually costs here in c/coa · 258 points · 1 year ago

fair enough

comment on the API source question that gets asked weekly, answered properly in c/compounding · 20 points · 1 year ago

Slight fix: the number was 94.2, not 95.1. Decimal point, but a fairly consequential one.

comment on is it normal to get constipation at week 29 in c/reconstitution · 9 points · 1 year ago

never post a calculation as advice without stating the concentration

permalink

comment on anyone else notice area percent kicking in around week 25 in c/coa · 80 points · 1 year ago

Cosigning. The batch number is load-bearing information.

comment on help me understand units, I have read the wiki twice in c/reconstitution · 73 points · 1 year ago

dead space is real and the syringe matters

permalink

comment on reconstitution vs mg/mL — genuinely asking which matters more in c/reconstitution · 28 points · 1 year ago

bacteriostatic and sterile water are not interchangeable, do not use them that way

no "told you so" comments, removed without discussion

comment on small win: dead space stopped being a problem at week 95 in c/reconstitution · 9 points · 1 year ago

Dead space ate 2 units on a low-volume draw. Tiny impact at 2.4mg, massive impact at 10mg.

comment on switched from 12.5mg to 0.5mg and the injection-site soreness got better, not worse in c/coa · 796 points · 1 year ago

Strongly agree. Mass% and area% are answering different questions on the same document.

comment on TB-500: the version I wish someone had shown me in week 1 in c/researchpeptides · 49 points · 2 years ago

I am going to push back on this slightly.

comment on small win: transit time stopped being a problem at week 11 in c/intlshipping · 7 points · 2 years ago

customs clearance often adds 22 days, factor that in

permalink

comment on tried DHL for 3 weeks. here is what happened. in c/intlshipping · 38 points · 2 years ago

The QYB lane used to be 13 days, now averaging 7. Carrier change or route congestion, unclear.

comment on [Discussion] can we stop arguing about area percent until somebody posts a number in c/coa · 84 points · 2 years ago

What is the method line say? Not the technique, the actual method.

permalink

comment on [Meta] the batch rule is doing its job and people should stop complaining in c/coa · 308 points · 2 years ago

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

comment on [Vendor] WXT order #5 — the Netherlands, 35 days, no drama, receipts inside in c/coa · 655 points · 2 years ago

the method line is doing real work, not just window dressing

chromatogram or it did not happen

comment on what changed for me between week 40 and week 89 in c/coa · 20 points · 2 years ago

area% is not mass%, and here is exactly why it matters

permalink

comment on week 91 check-in — 26kg down, fatigue manageable, one thing confusing me in c/reconstitution · 1 points · 2 years ago

show your working or it is unhelpful

Yes, exactly this, and it is the bit that took me 33 weeks to accept.

the concentration on the vial in marker is the most important step
