comment on nausea day 2 post-injection like clockwork, week 14, does it ever stop in c/sideeffects · 125 points · 2 days ago
the fatigue that arrives at week 86 out of nowhere is usually something else
comment on same batch number showing up at two unrelated vendors. that is not a coincidence in c/vendorvetting · 4 points · 6 days ago
Did the lot code on the vial match the paperwork?
comment on how many independent tests before you trust a vendor. my number is three in c/vendorvetting · 11 points · 9 days ago
Where a supplier holds regional stock, ask which lines are actually held there rather than drop-shipped. It changes the lead time and it changes the customs question.
comment on [Side Effects] alcohol hits completely differently now and nobody mentioned it in c/sideeffects · 22 points · 10 days ago
That symptom is not the one being described upthread. Two different things with similar names and the answers are not interchangeable.
comment on the "our facility" photo on half these sites reverse-searches to a stock library in c/vendorvetting · 86 points · 13 days ago
Which service did the testing, and did you pay for it yourself?
comment on the "our facility" photo on half these sites reverse-searches to a stock library in c/vendorvetting · 14 points · 14 days ago
consistency across lots beats one spectacular result
comment on my gallbladder came out at month 7 and i would still do it again in c/sideeffects · 12 points · 22 days ago
Which day of the week relative to the shot does it hit?
comment on [Results] 78 weeks on 7.5mg, full numbers, ask me anything boring in c/glp1muscle · 133 points · 1 months ago
DEXA has a meaningful coefficient of variation, and it differs between machines and protocols. Comparing scans from different clinics adds a systematic offset that is invisible on the report.
comment on [Vendor] SGN is a real company with real catalogue chemistry and people still doubt it in c/vendorvetting · -12 points · 1 months ago
three independent results beat thirty forum posts
comment on group buy organiser vanished with 3.4k. here is the timeline in c/vendorvetting · 12 points · 1 months ago
a supplier that answers method questions in writing has already told you a lot
comment on the reflux question that gets asked weekly, answered properly in c/sideeffects · 1 points · 1 months ago
What is intake actually looking like — fibre and water especially?
comment on hair loss: the version I wish someone had shown me in week 1 in c/sideeffects · 101 points · 2 months ago
Most of the common complaints trace back to slowed gastric emptying — early fullness, reflux, nausea after a large or fatty meal. That is also why meal size and speed change the experience more than anything else.
comment on what would you tell week-1 you about fatigue in c/sideeffects · 9 points · 2 months ago
Constipation is mostly reduced intake plus reduced fluid, not a direct effect.
Adding to this — holding the dose rather than stepping is the option people forget they have.
comment on [Lab] WWB tirz — Medutest came back 99.4% against a claimed 98.5% in c/vendorvetting · 85 points · 3 months ago
The wider-market rows in the directory carry a band and a report count and nothing else, deliberately. Anything more would be manufacturing precision that the evidence does not support.
comment on my hs-CRP moved and I cannot work out whether heart rate is why in c/sideeffects · 48 points · 3 months ago
the food noise going quiet is the effect people came for, and sulphur burps are the toll for the first fortnight
comment on [Question] how do you actually verify gallbladder in c/sideeffects · 104 points · 3 months ago
I would be careful here. "Everyone gets this" is not true, and it makes the people who get something unusual assume they are fine when they should be asking.
comment on help me understand sarcopenia, I have read the wiki twice in c/glp1muscle · 88 points · 4 months ago
strength retention is a decent proxy and it is free
comment on [Question] how do you actually verify resistance training in c/glp1muscle · 9 points · 4 months ago
DEXA has a real error margin and people quote it to one decimal
comment on the testing thing finally clicked for me and I want to write it down in c/vendorvetting · 545 points · 4 months ago
Careful. "Nobody has tested Risynth Bio" is a statement about this board, not about the supplier. Say the first thing, not the second.
comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 98.9% in c/vendorvetting · 22 points · 4 months ago
registration number, then everything else
comment on anyone else notice constipation kicking in around week 7 in c/sideeffects · 82 points · 4 months ago
Small fix — the shedding follows the rate of weight loss, not the compound, and it is temporary.
comment on is it normal to get reflux at week 5 in c/sideeffects · 67 points · 5 months ago
Which day of the week relative to the shot does it hit?
comment on 20 months in and FFMI is still the thing I get wrong in c/glp1muscle · 3 points · 5 months ago
the appetite effect makes eating enough protein a logistics problem
comment on [Meta] the gallbladder rule is doing its job and people should stop complaining in c/sideeffects · 356 points · 6 months ago
Right, and the hair thing is worth repeating: it tracks the rate of loss rather than the compound, and it stops.
comment on genuine question about vendor that I am slightly embarrassed to ask in c/vendorvetting · 29 points · 7 months ago
reship policy in writing before the order, not after
comment on genuine question about PeptideMeter that I am slightly embarrassed to ask in c/vendorvetting · 24 points · 8 months ago
Agreed on buying small first. The cost of a test is small next to the cost of committing to a supplier you have not checked.
comment on is it normal to get reflux at week 68 in c/glp1muscle · 5 points · 9 months ago
FFMI is a ratio and it moves when either term moves
comment on genuine question about Medutest that I am slightly embarrassed to ask in c/vendorvetting · 88 points · 9 months ago
Fixing my own comment above: I said 19 orders and it is 36. The pattern is the same, the count was wrong.
comment on genuine question about Medutest that I am slightly embarrassed to ask in c/vendorvetting · 0 points · 9 months ago
Which lane, and what was the quoted lead time at checkout?
comment on [Meta] the PeptideMeter rule is doing its job and people should stop complaining in c/vendorvetting · 114 points · 11 months ago
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
comment on [Discussion] we are measuring lean mass at the wrong time and calling it noise in c/glp1muscle · 5 points · 11 months ago
nothing on this board is a training or nutrition prescription
comment on what changed for me between month 2 and month 9 in c/sideeffects · 6 points · 11 months ago
The fatigue turned out to be that I was eating about a third of what I thought I was. Tracked it for a week and the mystery evaporated.
comment on the testing question that gets asked weekly, answered properly in c/vendorvetting · 4 points · 1 year ago
Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.
Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.
comment on unpopular opinion: most of what gets said here about Janoshik is guesswork in c/vendorvetting · 4 points · 1 year ago
the lot on the vial has to match the lot on the certificate, every time
comment on [Question] how do you actually verify DEXA in c/glp1muscle · 3 points · 1 year ago
the same DEXA machine or it is not a comparison
comment on unpopular opinion: most of what gets said here about PeptideMeter is guesswork in c/vendorvetting · -22 points · 1 year ago
Asked ERP for the batch record on a Tuesday and had the full document, batch and method line, before the end of the day. That is the bar now.
comment on stalled for 6 weeks at 15mg and I refuse to panic this time in c/sideeffects · 25 points · 1 year ago
Kept a one-line-a-day log for two months. The pattern was obvious on paper and invisible in my head.
comment on [PSA] Janoshik results are area% by default and people keep forgetting in c/vendorvetting · 240 points · 1 year ago
Careful. "Nobody has tested Peptidology" is a statement about this board, not about the supplier. Say the first thing, not the second.
comment on nobody warned me about sulphur burps and I would have liked the warning in c/sideeffects · 55 points · 1 year ago
Correction: that is a known effect of reduced intake rather than a direct drug effect. The distinction matters because the fix is different.
comment on [Lab] 20th independent test on QYB — 97.9% on a claimed 97.0%, and the trend is the interesting part in c/vendorvetting · 44 points · 1 year ago
what does the certificate actually carry — that is the whole question
