comment on is 96.8% area% actually fine or am i being sold a rounding error in c/coa · 92 points · 1 days ago
this thread has already been worth more than the last twenty i read
comment on [Seizure] letter arrived, no prosecution, here is exactly what it said in c/customs · 2 points · 2 days ago
Asked somebody qualified locally rather than relying on this board. Best forty minutes I have spent on the topic.
comment on WXT and BCH put water content on the COA when nobody asks for it, and i think that is the tell in c/vendorvetting · 88 points · 2 days ago
i genuinely did not know water was invisible to the detector. that reframes about half of what i thought i understood.
comment on is 96.8% area% actually fine or am i being sold a rounding error in c/coa · 214 points · 2 days ago
oh. so the number is not the issue, the missing breakdown is the issue.
comment on two labs, same vial, 98.1 and 96.4. both right? in c/hplc · 71 points · 2 days ago
i have been treating the higher number as the true one this whole time. edit: and specifically i once emailed a vendor about a 1.2 point gap. i would like that email back.
comment on [Janoshik] SSA tirz 10mg — 99.1%, third batch in a row above 99 in c/labresults · 52 points · 2 days ago
i had absolutely made that mistake before reading this
comment on is 96.8% area% actually fine or am i being sold a rounding error in c/coa · 71 points · 2 days ago
doing that. edit: sent to Janoshik, will post in c/labresults either way even if it makes me look silly.
comment on [Explainer] area% is not mass% and here is exactly why it matters to your vial in c/coa · 74 points · 3 days ago
i have been on this site four months and this is the first time the two numbers have made sense. edit: went back and re-read three of my own old posts and i was confusing them in all of them.
comment on [Country Guide] personal import rules, my country, with the actual citations in c/customs · 106 points · 3 days ago
Shipped from regional stock or from origin?
comment on bought a second-hand HPLC. worst best decision of my life. AMA in c/hplc · 143 points · 3 days ago
genuine question — did it change what you buy, or just how you talk about it?
comment on net peptide content vs purity — two different numbers, same vial, and only one is on your COA in c/coa · 68 points · 5 days ago
so a 10mg vial might have nine milligrams of peptide and everyone involved has been honest. edit: yes, per the table in the other thread. this is the least satisfying accurate answer i have received.
comment on QSC: six tests over three years, 0.9 points of spread, and what that actually tells you in c/labresults · 71 points · 5 days ago
the naming situation in this industry is genuinely hostile to newcomers
comment on [Concluded] 104 weeks. final numbers. thanks for reading. in c/dosinglogs · 66 points · 20 days ago
waist monthly, weight weekly, notes whenever
This is the whole discipline in one line. Contemporaneous, consistent, minimal.
comment on [Question] how do you actually verify personal import in c/customs · 8 points · 24 days ago
if it matters, ask somebody qualified in your own jurisdiction
comment on what changed for me between month 9 and month 13 in c/dosinglogs · 3 points · 1 months ago
Are the missed weeks in there as blanks or dropped entirely?
comment on someone explain import to me like I have not read a paper in years in c/customs · 21 points · 2 months ago
Clearance took four days and the carrier took eleven. I had been blaming entirely the wrong stage for a year.
comment on [Struggle] regained 6kg over a winter and i am posting it anyway in c/progresspics · 18 points · 2 months ago
Rate of change is not a virtue.
Adding the thing I wish someone had said to me — the goal you picked at week one was a guess.
comment on log is the most under-discussed thing on this board in c/dosinglogs · 35 points · 3 months ago
Retitled — a log is a record, not a protocol, and the original read as a schedule for others to follow.
Disagreeing with this bit: daily weighing gives you noise and costs you something.
Here it is: 72 weeks on 12.5mg, full numbers, ask me anything boring. One person, one log, no control group, so read it accordingly. 72 weeks and 12.5mg — those are the…
comment on what would you tell week-1 you about struggle in c/progresspics · 5 points · 8 months ago
Removed an image link.
This is the one I would put in the sidebar. The middle is where everyone lives.
comment on the log question that gets asked weekly, answered properly in c/dosinglogs · 2 points · 10 months ago
consistent conditions or you are logging noise
comment on genuine question about timeframe that I am slightly embarrassed to ask in c/progresspics · 52 points · 10 months ago
Yes. The middle is where everybody actually lives and almost nobody posts from it.
comment on unpopular opinion: most of what gets said here about customs is guesswork in c/customs · 30 points · 10 months ago
Research-use-only labelling is a description of intended use, not a customs classification.
Agreed — read the notice before deciding what has happened. Most of the panic here is misclassification.
comment on [Meta] the non-scale victory rule is doing its job and people should stop complaining in c/progresspics · 7 points · 11 months ago
What timeframe is that over?
comment on three years of seizure threads, summarised so you do not have to read them in c/customs · 201 points · 11 months ago
Kept every document including the dull ones. When a process started, having the dates in order made it short.
comment on [Discussion] we are measuring personal import at the wrong time and calling it noise in c/customs · 22 points · 1 year ago
the answer for Canada does not apply anywhere else

Are the missed weeks in there as blanks or dropped entirely?
comment on [Results] 64 weeks, 15kg, and waist was the hard part in c/dosinglogs · 1 points · 1 year ago
What are you actually recording each week?
comment on [Results] 64 weeks, 15kg, and waist was the hard part in c/dosinglogs · 5 points · 1 year ago
Wrote the concentration into the log as well as on the vial. Have referred back to it more than once.
Reporting in. 64 weeks, 15kg, and waist was the hard part. The relevant figures are 64 weeks and 15kg, and they come from the same log I have kept the whole time.…

Is the concentration recorded anywhere in the log?
comment on personal import — 11 things I got wrong before I got it right in c/customs · 10 points · 1 year ago
Got a request for information and treated it as a seizure for two days before actually reading it. It was neither dramatic nor difficult.

Agreed on asking what documentation accompanies a shipment. Suppliers who ship regionally usually have a clear answer.

The rules where I live changed between two orders six months apart. Nothing was announced; I found out by reading.

comment on my ferritin moved and I cannot work out whether tracking is why in c/dosinglogs · 24 points · 1 year ago
Yes — log what happened rather than what you intended. My retrospective entries were quietly wrong every time.
comment on my ferritin moved and I cannot work out whether tracking is why in c/dosinglogs · 14 points · 1 year ago
a log is not a plan and it is not advice for anybody else
comment on [Question] declared value — what am I missing here in c/customs · 4 points · 1 year ago
keep the paperwork, including the boring parts
