[Lab] identity confirmed but net peptide content was 71%

Lab Clean Column ×2 Sourced ×1

Trying to settle this properly because the thread from last year went in circles.

The claim: tendon matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 5 months without either producing anything.

What would actually settle it is 7 people measuring the same thing the same way. I have started; my numbers are below. They lean one way but not strongly enough for me to declare victory.

If you have data, post the data. If you have an opinion, flair it as an opinion.

The thing nobody prepared me for was the quiet. Not the appetite, the quiet. The constant negotiation in my head about food just stopped.

the regulatory rodent evidence is solid, human evidence is not

Flair changed to match the content. Read the sidebar before posting next time and we are square.

Disagree on that part. 98.7% and 99.3% on the same vial is normal.

This is correct. The naming is genuinely confusing.

Did anything else change in the same window?

My version of this: I was so worried about the injection that I put it off for eleven days. The injection is the easiest part.

Yeah, rodent data does not scale to humans.

Slight fix: the number was 98.7, not 98.9. Decimal point, but a fairly consequential one.

Yes, exactly this, and it is the bit that took me 59 weeks to accept.

Came off after 83 weeks for financial reasons. Regained about a third over the following year. Back on now at a much lower dose.

Titration speed is a side-effect dial far more than an efficacy dial.

Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.

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.
