Growth Hormone Peptides

This is the category with the widest internal spread on the whole site. Two compounds here share a name and differ by a factor of roughly 384 in half-life, which makes it the category where copying someone else's protocol goes wrong most often.

The shared pattern: there isn't one

That is genuinely the point. This category runs from CJC-1295 without DAC at roughly 30 minutes to CJC-1295 with DAC at roughly 8 days — the shortest and the longest half-lives on the entire site, under nearly the same name.

The Drug Affinity Complex is the whole difference: it binds the peptide to serum albumin, which slows clearance enormously. Same base analogue, incomparable pharmacokinetics. Anyone reading "CJC-1295" in a protocol without checking which version is being described is reading an ambiguous instruction.

MK-677 is the other outlier — it is oral and not a peptide at all, a small molecule acting on the same pathway. It has no vial, no reconstitution, and no syringe arithmetic.

What that means for a log

• Be explicit about which CJC-1295 you mean. The two versions need separate entries and are not interchangeable in any record.
• Short compounds need clock times; long ones do not. Ipamorelin and no-DAC live inside a couple of hours. DAC lives for weeks.
• Oral entries need no concentration field. MK-677 is date and amount only.
