what would you tell week-1 you about handling

Question Well Actually ×9 Cold Box ×1

Confession thread, sort of.

I went from 2.5mg to 1.0mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 8 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway.

So now I have early fullness I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 24 reads it before doing the same thing.

Tracking number removed. It identifies both ends of a shipment.

Second this question. I have wondered about thymosin for 9 months and never seen a straight answer.

Disagree. What you are describing is consistent with identity, not with what you concluded.

Sweden here. Waited 3 months on a list, gave up, went private, and the total cost was roughly what I expected.

What was the batch number and which service?

Slight fix: the number was 97.6, not 97.4. Decimal point, but a fairly consequential one.

I am going to push back on this slightly.

name the compound precisely, TB-500 and Thymosin Beta-4 are not the same

thymosin fragments, GH secretagogues, secretagogue, long tail

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, identity is the first question.

u/osman_ferrari26 points·7 months ago

Has anyone actually got this in writing, or is it forum lore at this point?

u/gustav_solberg35 points·7 months ago

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

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

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

everything else in the vial drawer, secretagogue

Disagree on that part. 98.1% and 99.2% on the same vial is normal.
