Peptides, from first principles
What a peptide is, what it is not, why almost all of them need a needle, and the evidence grade behind each category.
Primers
The background the graded entries assume. Deliberately unexciting: no protocols, no doses, no promises.
Available primers
Choosing what to run
Pick one goal, match it to a category, and set out in advance what would count as it working.
What can go wrong
Side effects worth expecting, risks worth taking seriously, who should not start at all, and the symptoms that mean stop now.
Doing the arithmetic
Reconstitution, concentration and injection volume. The maths is simple; the unit errors are not forgiving.
Reconstituting a vial
Why it arrives as powder, what you need, the procedure step by step, and the handling mistakes that ruin a vial.
Storage and stability
Why the powder is stable, the four things that degrade it, the two clocks that start when you add water, and per-compound handling.
Giving the injection
Subcutaneous technique, where to site it, needle choice, rotation, and what is normal afterwards.
The nasal route
Which compounds actually absorb through the nose, which need a needle, and why “absorbs” and “works” are two different questions.
