THE PROBLEM NOBODY WARNED YOU ABOUT

Kitchen fridges weren't built for peptides.

Every time that door opens, more than 20 times a day, the temperature rises. Meanwhile the back wall runs cold enough to freeze a vial solid against the vents. Add the artificial light and moisture, and the compound you paid for loses its potency faster than you think - with zero visible signs to warn you.

THE MECHANISM

ThermaLock™  precision cooling

Most coolers work in bursts. The compressor kicks in, cools too far (below 0°C / 32°F), shuts off, drifts warm (above 10°C / 50°F) , then kicks on again. That constant swing is what degrades your compounds.

Our ThermaLock mechanism works differently. It's solid-state - no compressor, no bursts. A sensor checks the internal temperature, again and again in real time, and makes tiny adjustments to keep it level.

So the temperature stays flat instead of swinging. Your vials sit in one constant temperature all day - and the live number on the front means you never have to guess.

One ruined protocol can cost more than the device itself. PeptiCooler pays for itself the first time it saves what’s inside.

Built by people who vet EVERYTHING

  • "I used to store bpc, tb, sermorelin and frag on the top shelf of the fridge. Now I don't have to worry"

    Brad B.

  • "Sat in my hot car for an hour during a heatwave and held temp the whole time. That's when I knew it was worth it. Really happy with it."

    Jenny P.

  • "Vetted the vendor, read the COAs, did everything right, then kept them in the fridge door like an idiot. Didn't realise it was so bad. Sorted now"

    STRAIGHT ANSWERS

    The questions a careful person asks.

    Nope, it has a built-in battery for travel that lasts from 8-10 hours on a full charge - charged via USB

    No problem, the PeptiCooler has a built-in battery that lasts for 8-10 hours when power is lost. (That’s 8-10 hours longer cooling than your kitchen fridge during a power cut)
