Peptide Guides
Bacteriostatic (BAC) water is sterile water with 0.9% benzyl alcohol. Sealed, it lasts until the expiry printed on the vial; once punctured, US guidance is to discard it within 28 days. Here is how much to add, how to work out syringe units, and what the label says about storage.

Adamax is sold as an adamantane-modified version of Semax, the Russian-developed ACTH(4-10) analogue. Semax has a small, mostly Russian-language clinical literature. Adamax has almost none, and even its structure is described inconsistently.

Peptide Comparisons
Eloralintide and cagrilintide are both once-weekly amylin analogues in development for obesity. They differ in which receptors they prefer, in who makes them, and in what each has been paired with in trials. Neither is approved.

Peptide Comparisons
Eloralintide and retatrutide are both once-weekly investigational injections from Eli Lilly, but they act on different hormone systems. What each one targets, what their trials measured, and why no trial has compared them.

Bloating, burping and gas are listed adverse reactions on the Wegovy, Zepbound and Saxenda labels, and all three labels say the drugs delay gastric emptying. How often the trials reported them, when they tend to happen, and which symptoms the labels treat as warning signs.

A few peptides are FDA-approved as nasal sprays, and their labels show how little of a spray is absorbed: 3–5% for calcitonin. What the approved sprays and the research studies show, and why a research spray has none of that data.

CJC-1295 with DAC binds to albumin and lasts days; the version sold as no DAC (Mod GRF 1-29) lacks that group and is short-acting. Only the DAC form has published human data. What the difference is and what was studied.

Peptide Comparisons
Kisspeptin and PT-141 (bremelanotide) both come up in research on sexual desire, but they act on different systems. One is an FDA-approved medicine for one narrow indication; the other has only short academic studies. How they differ.
