write down when it starts and stops, the pattern is the useful part

reflux at night, try not eating in the three hours before bed

Which week did the appetite change actually land for you?

Constipation is mostly reduced intake plus reduced fluid, not a direct effect. That is why the boring fibre and water answer keeps working.

Agreed. Identity is the question here. A short peptide can be synthesised by almost anyone and the sequence is what you are actually buying.

Right. And the sema-to-tirz "conversion" people post is invented. There is no published equivalence.

the trials titrated on a calendar, real people titrate on symptoms

Push back on the goal number.

Adding the thing I wish someone had said to me — the goal you picked at week one was a guess.

SURMOUNT-1 landed around 21% at 72 weeks on the top arm

teodor_szabo is right that the two molecules are not interchangeable. There is no published conversion and the ones circulating are invented.

Cosigning that the papers are more modest than the summaries of them. That is true across this whole site and especially here.

stepping every four weeks is a ceiling on speed, not a schedule you must hit

Sent a vial to Janoshik: 99.4% against a claimed 98.5%, with the mass confirming the sequence. Both halves mattered to me.

switching from sema is not a dose conversion, there is no clean equivalence

Weekly dosing again, half-life in the same neighbourhood as sema, so a step change takes about a month to reach steady state. Judging a new step at day five is judging noise.

Which paper is that claim from, and was it in humans?

nobody owes anybody a starting weight

the four-week step schedule is the label, not folklore

What step are you on and how long have you been there?

14kg over 53 weeks, never went past 10mg, and reflux stayed mild the whole way. Posting because the loud threads are all 15mg.

Held 7.5 for five months. Everyone kept asking when I was going to 10. The answer was never, because 7.5 was working.

Every claim I could trace in this board went back to about four papers. That was a sobering afternoon.

goal weights chosen at week one are usually guesses

Why identity, not purity, is the test to buy here.

This is a short peptide with a published sequence. Synthesis is not difficult, which means the market is wide and the analytical question shifts. A high area-percent figure tells you the sample is homogeneous; it does not tell you the homogeneous material is the sequence you ordered.

Mass spectrometry, with the theoretical mass alongside the measured one, converts a purity claim into an identity claim. It costs a little more and it answers the question that actually matters. Ask for it, and ask suppliers whether they can provide it before you order — the answers are informative in themselves.

Which service, and did you pay for it yourself?

Yes. I stepped to 12.5 because the calendar said so, not because anything needed fixing, and I regretted it for a fortnight.

Appetite effect for me is flat across seven days. On sema it was a wave. Same person, different molecule.

stepping every four weeks is a ceiling on speed, not a schedule you must hit

Have now spent more on testing than on some of the orders. No regrets — the log is the reason I can buy without agonising.

Are you comparing yourself with the trial mean or with the people who post the most?

fibre and water before you buy anything to fix it

Which day of the week relative to the shot does it hit?

Bought four different things to fix my sulphur burps. What actually worked was eating half as fast.

early fullness on day two and gone by day four is the standard shape

Not sure that follows. You went up a step and changed your training in the same fortnight.

Disagree that this is a discrepancy. 98.1% against a claimed 97.5% is inside ordinary inter-lab variance in either direction.

2.5mg is a four-week starting dose, not a maintenance dose. Worth being precise since people search these threads.

What method produced that purity number?

a rough fortnight at each step is normal, a rough three months is not

Correcting my own comment above: I said day three and my log says day two. Same pattern, wrong day.

if it is severe or persistent that is a clinician question, not a board question
