The unglamorous side of keeping a logbook — handling, storing and getting rid of things properly. Search below if you've got a vial open and one question. No dosing advice, no vendors.
Aim the water at the glass, let it stand, and roll it between your palms until the powder has completely gone. Step by step, plus the things not to do.
Filtering the water going in costs you nothing; filtering a mixed vial costs you peptide. What 0.22 µm removes, what it can't, and when reaching for a filter is the wrong answer.
Where sealed powder and mixed vials should actually live, what really degrades a peptide, travelling with vials, and what to do when the power goes off.
Which vials must stay cold and which tolerate room temperature, how long one can be left out, and what heat, light and freeze–thaw actually do.
The reconstituted clock: roughly how long a mixed vial keeps in the fridge, frozen or warm, why sealed powder lasts far longer, and how to date yours.
Peptides vs steroids, SARMs and GLP-1s. Is tirzepatide a peptide, is ibutamoren a steroid — a plain-English classification with a quick table.
What the mg number, ‘lyophilised’, ‘preservative free’, ‘research use only’, batch numbers and the dates on a vial actually mean.
What actually counts as a sharps container, how to fill and seal it, where to take it, and the mistakes that cause needlestick injuries.
Every compound's refrigerated and frozen window in one sourced table, with the limitations spelled out. Free to cite.
Once mixed, yes — keep it around 2–8°C. Sealed powder tolerates short room-temperature spells but is stored cold, and frozen for the long term. Follow your own vial's instructions.
StorageA few hours to warm up or in transit is generally fine, especially for sealed powder. A mixed vial left warm for days degrades much faster — heat is the biggest factor.
StorageSealed powder freezes well. A reconstituted vial can usually be frozen once to extend it, but avoid repeated freeze–thaw cycles.
StorageCommonly quoted at about 28 days refrigerated, ~60 days frozen once, and only a few days at room temperature. Sealed powder lasts far longer. Exact figures vary by compound.
BasicsYes — tirzepatide is a peptide (a chain of amino acids) acting on the GLP-1 and GIP receptors. Semaglutide and retatrutide are peptides too.
BasicsNeither. MK-677 is an oral small-molecule growth-hormone secretagogue — not a peptide and not an anabolic steroid, which is why it's stored and taken differently.
BasicsIt's the total mass of dry peptide in the vial — not a dose and not a concentration. Concentration only exists once you add a known volume of water.
MixingRolling is the safer default. Aim the water at the glass wall, let it stand, then roll gently between your palms until the powder has gone.
MixingAt the glass wall above the powder, so it runs down rather than blasting into the cake. A hard stream straight into the powder foams it.
MixingLet it stand a few minutes, then roll. Most vials that look like they need help just need more time — not more force, and not a filter.
MixingBacteriostatic water for anything you'll draw from more than once — the preservative is the point. Check what came with your vial.
FilteringBefore, if at all. Filtering the water on its way in costs you nothing because the peptide never touches the membrane. Filtering a mixed vial loses some of the peptide.
FilteringOnly when the peptide goes through the membrane. Peptides adsorb to filter surfaces, and a dilute vial loses a bigger proportion than a concentrated one.
FilteringNo. Endotoxin is far smaller than a 0.22 µm pore and passes straight through. Filtered is not the same as sterile-manufactured.
FilteringNo. Cloudiness is information, and filtering removes the information rather than the cause. Usually it simply hasn't finished dissolving.
FilteringEvery filter holds liquid back in the housing and membrane. Read the volume that actually reached the vial and calculate your concentration from that number.
FilteringThe question doesn't split that way — a membrane responds to particle size, not chemical class. NAD+, methylene blue and glutathione simply behave differently on a filter.
StorageSealed powder and reconstituted vials have different needs, and freezing a mixed vial is its own decision. The guide splits the two cases.
StorageIt depends on the compound and how it's stored. Write the mix date on the vial the moment you mix it — that's the number people lose, not the vial.
StorageBoth are covered — what a few hours out of the fridge actually means, and how to carry vials without cooking or freezing them.
StorageFor some compounds it does. Keeping vials in a box or a case rather than on an open shelf costs nothing.
SharpsA proper rigid, puncture-proof container with a lid. The guide covers what qualifies and what doesn't.
SharpsIt varies by country and local authority — pharmacies, councils and clinics are the usual routes. Never household waste.
SharpsNever recap a used needle, never overfill the container, and don't push anything down. Those three cover most injuries.
Shelf lifeThe reference table gives a refrigerated and frozen window per compound, with sources and the limitations stated.
Shelf lifeEnter the mix date in the shelf-life tool and it works out where you are in the window.
CostThe cost-per-dose tool divides the vial price by the doses it really holds, so you can compare vial sizes honestly.
ScannerYes — the free scanner reads the compound and strength off a vial photo. No account, and nothing is stored.
Nothing matched that. Try a single word — shake, filter, cloudy, endotoxin, fridge, freezer, travel, sharps, cost.
