Supply guides that answer the question
Short guides to the products themselves — what the words on a listing mean and which one to buy. Nothing here is medical advice; for health questions, ask a licensed clinician.

How to read a supply listing before you buyTwo listings for the same thing can differ on everything that matters. What to check, in the order it bites people.
Where to buy peptide supplies (and what to avoid)Which source suits which item — and the sellers to walk away from.
Bac water vs. sterile water (and which to buy)Bac water, sterile water and saline are not interchangeable. Which one your vial needs, how much to add, and why an opened bottle has a clock on it.
Syringes and needles, translatedGauge, units and barrel size decoded — including why a bigger gauge number means a thinner needle.
Doing it right
Units and millilitres: a conversion tableThe conversion table: what every marking on a U-100 syringe is worth in millilitres.
Measuring accurately — units, bubbles and dead spaceThe mechanics of an accurate measurement: reading units, clearing bubbles, and where volume quietly goes missing.
Sterile technique at homeSterile technique at home is a short list of habits. Here they are, and what to do when you break one.
Mixing (reconstituting) a vial, step by stepThe standard reconstitution technique, step by step, in terms of the supplies it actually takes.
Subcutaneous vs. intramuscular: what supplies each needsThe two routes need different needles, different syringes and different drawing-up kit. What each one asks you to own — and the mismatch that catches people out.
Keeping it cold
Storing and traveling with temperature-sensitive vialsWhere a vial should live, what light and temperature do to it, and how to carry one without ruining it.
Peptide fridge: choosing one, and proving it's actually coldA peptide fridge is just a mini fridge that holds its temperature. Why the door is the worst shelf, and how to prove yours stays at 2–8 °C.
Keeping things cold: every option comparedMini fridge, ice packs, cooling wallet or car fridge — what each one is actually for.
Flying with syringes and cold packsWhat airport security actually allows, the rule people get caught by, and how to make screening quick.
Kit and comfort
Pens vs. vials and syringes: what supplies each one needsNew to injecting at home with a pen? It needs remarkably little. The three things to buy, and what a vial needs instead.
Nasal, oral and topical suppliesSprays, atomizers, oral syringes and dropper bottles — where consistency comes from the container, not your aim.
Alcohol pads, chlorhexidine or barrier wipes?Alcohol pads, chlorhexidine and barrier wipes do overlapping jobs. Which to use when.
Making injections hurt lessMost of the sting is technique and equipment, not tolerance. What makes the biggest difference, in order.
Afterwards
Sharps containers: choosing one, and getting one freeSharps bin or sharps container, same job. What makes a good one, how to use it — and the places that will give you one free.
How to dispose of a full sharps containerA full container doesn't go in the bin. Every route out — council collection, pharmacy take-back, drop-off, mail-back — and which ones exist where you live.
How long supplies last, and how to tell when they're doneSupplies expire three different ways. The printed date is only one of them.
Where to check official information yourselfThe free, official places to check a product label, your local sharps rules and what airport security allows — by country.
