comment on [PSA] your bac water is fine, your fridge door is not in c/reconstitution · 44 points · 2 days ago
the concentration on the vial in marker is the most important step
comment on foam means you shook it. do not shake it in c/reconstitution · 14 points · 3 days ago
That is net peptide content, not purity. Different number, different meaning.
comment on [Explainer] why 1mL syringes cause overdoses and 0.3mL ones do not in c/reconstitution · 24 points · 3 days ago
30mg vial, 1mL water, concentration is 30/1 — write it on the vial afterwards
comment on sterile water is not bacteriostatic water and it is not close in c/reconstitution · 29 points · 6 days ago
i am begging people to write down the concentration
comment on [Suspicious] identical chromatogram on two different compounds from the same vendor in c/coa · 26 points · 8 days ago
area% is not mass%, and here is exactly why it matters
comment on how many independent tests before you trust a vendor. my number is three in c/vendorvetting · 105 points · 9 days ago
comment on [COA] what does "related substances 1.4%" actually mean for my vial in c/coa · 3 points · 12 days ago
This is the correct framing. The COA structure matters as much as the number.
comment on [Vendor] JEEP six orders in, zero problems, and i am suspicious of my own luck in c/vendorvetting · 3 points · 17 days ago
the reship rate on QST is actually pretty consistent
comment on anyone else notice certificate of analysis kicking in around week 75 in c/coa · 8 points · 1 months ago
Cosigning. The batch number is load-bearing information.
comment on Germany: water content, and what it actually costs here in c/coa · 26 points · 2 months ago
axis labels included, always
comment on unpopular opinion: mg/mL is massively overrated in c/reconstitution · 86 points · 2 months ago
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
comment on switched from 15mg to 12.5mg and the sulphur burps got better, not worse in c/vendorvetting · 72 points · 2 months ago
comment on what would you tell week-1 you about certificate of analysis in c/coa · 6 points · 3 months ago
The COA I was holding said 96.8% area and I thought it was trash. Turns out the method was solid and the impurity profile was clean.
comment on [Meta] proposal — a flair for reship posts in c/vendorvetting · 22 points · 3 months ago
did they reship, credit, or ghost you?
comment on [Meta] proposal — a flair for certificate of analysis posts in c/coa · -8 points · 3 months ago
the related substances line is where the story is
comment on [Discussion] bacteriostatic water is doing more work than we give it credit for in c/reconstitution · 2 points · 3 months ago
dead space is real and the syringe matters
Disagree on that part. 99.0% and 98.9% on the same vial is normal.
comment on [Question] mg/mL — what am I missing here in c/reconstitution · 6 points · 4 months ago
dosing errors come from people reconstituting two vials differently and forgetting which is which
comment on my ApoB moved and I cannot work out whether non-scale victory is why in c/progresspics · 7 points · 4 months ago
text removes the body-shaming pile-on
comment on water content — 5 things I got wrong before I got it right in c/coa · 41 points · 4 months ago
PDF metadata is checkable in fifteen seconds
comment on France: mg/mL, and what it actually costs here in c/reconstitution · 1 points · 6 months ago
Slight fix: the number was 99.1, not 93.7. Decimal point, but a fairly consequential one.
