my ferritin moved and I cannot work out whether contraception is why

Results Receipts ×3

Right, the fertility question again, but with numbers this time.

I have 12 data points over 26 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.

The thing I would flag for anyone new: the effect I am describing showed up at week 23, not week 72. People give up long before the interesting part.

Interested in whether this matches other people's logs or whether I am an outlier.

You have restated the marketing copy. What is the actual substance here.

cycle changes are real and under-researched

Stalled for 21 weeks, changed nothing, and it started moving again on week 45.

hair-loss on contraception is real

Not to be pedantic but contraception and perimenopause are being used interchangeably and they are not interchangeable in real life.

Respectfully this is a sample of one presented as a finding.

The muscle cramps was genuinely awful for three weeks and then simply stopped. I know that is not useful information, but it is what happened.

Did anything else change in the same window?

Mechanistically the bit that matters is fertility. It explains most of the early profile and a decent chunk of the outcome.

Which country? Half the answers in this thread only apply in Germany.

PCOS and insulin resistance

PCOS and insulin resistance

Disagree on that part. 98.1% and 98.3% on the same vial is normal.

u/dose_creep_dan10 points·1 year ago

Small correction: the trial was 5 weeks, not 29. Does not change your point but people will quote it.

Adding to this: fertility is doing more work than the comment implies.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

Disagree on that part. 96.2% and 96.8% on the same vial is normal.

Strongly agree. Cycle changes are documented.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

About c/glp1women

The questions the trials under-powered: PCOS and insulin resistance, cycle changes, fertility signal and contraception interactions, perimenopause and menopause weight physiology, and the fact that the pregnancy answer is always "not while trying, talk to your clinician".
