Does 1P LSD Go Bad? Everything You Need to Know

Published:

Lysergic acid diethylamide, also known simply as LSD or acid, was first created in 1938.
It exploded in popularity in the 1960s and is one of the first known examples of a man-
made psychedelic drug. When the world’s governments saw how much joy it brought to
people, they decided to make it illegal because we can’t have nice things. The desire to
develop legal alternatives has been going strong ever since.

What Is 1P LSD?

1P LSD (1-propanoyl-lysergic acid diethylamide) is a research chemical with many of
the same properties and effects as LSD. Just like the similar research chemical 1B LSD,
it metabolizes into LSD after ingestion. It activates the brain’s serotonin receptors just
like LSD, and the effects are virtually indistinguishable.

Does 1P LSD Go Bad?

Safety is extremely important when experimenting with any substance. The good news
is that if stored correctly, 1P LSD can last for many years with no noticeable loss in
quality and no adverse effects.
The bad news is that your supply will soon be ruined if stored incorrectly, flushing your
hard-earned cash down the drain. This means that proper storage of 1P LSD is
essential to preserve your stash and ensure its full potency remains intact.

How to Properly Store 1P LSD

Many environmental factors accelerate the degradation of 1P LSD, so the goal is to
eliminate them as much as possible. UV light (sunlight), oxygen, moisture, and

temperatures above 25°C are all contributing factors. There are a few key things to
keep in mind when storing your 1P LSD.

  1. Wrap your blotter paper in tinfoil. This will protect your tabs from light and moisture
    damage.
  2. Place your blotter paper in an air-tight container. This will prevent oxygen from
    breaking down your 1P LSD. Avoid using clear containers, as they allow light to enter
    and degrade your stash. The colour of the container is not important as long as it will
    not allow light inside.
  3. Add a silica gel packet to the container. This is especially important if you live in a
    humid environment. Silica gel packets absorb moisture from the air, ensuring the inside
    of the container remains perfectly dry.
  4. Place the container inside of a fridge or freezer. 1P LSD will remain quite stable at
    temperatures of 25°C and below but will quickly degrade as the temperature rises.
    Depending on where you live and the time of year, this might not be necessary, but it’s
    good practice to get into the habit of doing it every time.

What Happens if 1P LSD Goes Bad?

Now that we know 1P LSD can go bad if stored improperly, it’s important to know the
consequences. So many things can negatively affect it, but the result of all of these
factors is the same: loss of potency.
1P LSD will not become dangerous to ingest due to age or other external forces. The
worst-case scenario will be expecting to have a great night and being left disappointed.
Although these research chemicals can be fairly cheap compared to the real thing, it’s
always disappointing to find out your money has been wasted.

Final Thoughts

So, does 1P LSD go bad? We now know that it does, in fact, go bad, but fortunately, it is
very easy to prevent that from happening. It takes very little effort to protect your 1P
LSD from breaking down due to the elements, and it’s well worth doing properly. The
best way to find out if your 1P LSD has gone bad is to try it. The worst that will happen
is a feeling of deep regret when you realize you should’ve taken the time to store it
properly.
