is it normal to get sulphur burps at week 34

Question Clean Column ×7 Receipts ×3

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

I have 11 data points over 38 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 92, not week 46. People give up long before the interesting part.

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

Sceptical. If this were true we would see it reflected in the data and we do not.

pentadecapeptide is sequence, the supply chain naming is a mess

sequence and naming claims need the actual sequence

Crossposting this to c/vendorvetting because the people who need it are not reading this community.

Second this question. I have wondered about pentadecapeptide for 13 months and never seen a straight answer.

Yeah, rodent data does not scale to humans.

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

Removed a chain here. The rule is one line long and it is not negotiable.

Strongly agree. Zero human controlled data.

This is correct. The naming is genuinely confusing.

near-zero controlled human data, full stop

The confident tone is doing a lot of work that the evidence is not.

tendon and rodent data literature in rodents is interesting

u/tomas_kimani7 points·1 year ago

the sequence variation is the real issue

the sequence variation is the real issue

Disagree on that part. 99.2% and 99.0% on the same vial is normal.

That is net peptide content, not purity. Different number, different meaning.

rodent data must be labelled as rodent data

BPC regulatory is a naming problem, three things are called this

replysharereportpermalink
u/karim_hartmann17 points·1 year ago

Not to be pedantic but tendon and BPC-157 are being used interchangeably and they are not interchangeable in real life.

replysharereportpermalink
u/nikhil_lindqvist15 points·1 year ago

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

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

About c/bpc157

BPC-157 as it actually is: a pentadecapeptide with a genuinely interesting rodent tendon-and-gut literature, near-zero controlled human data, a naming and sequence mess in the supply chain, and a regulatory status that changed sharply in several countries.
