Reading a rodent study on a secretagogue without over-extrapolating — the long version posts 61–67

Coming back to post #59, because the follow-up matters more than the original answer.

Why this subcategory is stricter about sourcing than most: the evidence base is weaker and that is precisely why documentation quality matters more. A supplier page that clearly identifies the compound and the purity is more valuable for secretagogues than for incretin agonists where the evidence base is stronger.

Secretagogues and glucose tolerance: there is a mechanistic concern that sustained growth hormone elevation might impair glucose tolerance. The clinical relevance of this concern in practice is not well established.

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.

post #63 answers the question as asked. The question underneath it is different.

Development history is more informative than speculation: ipamorelin was investigated clinically for post-operative ileus and was not taken forward to registration. That it was not brought to market tells you something about the cost-benefit calculation that any amount of forum enthusiasm does not.

CJC-1295 with and without DAC: the version with a drug affinity complex binds albumin covalently and persists for days. The version without it does not persist. Supplier labelling frequently does not distinguish them clearly, so confirming which you have is important.

Worth separating two things that post #63 runs together.

Ipamorelin selectivity claims originate in preclinical characterisation and are reasonably well supported for what they claim: less effect on cortisol and prolactin than earlier GHRPs. Whether that translates to something clinically meaningful is a different question from whether the selectivity is real.
