Is DIYing Testosterone Illegal?

In most countries, testosterone is a controlled substance. Meaning it’s legally regulated and depending on the country, punishable by law to possess or sale without license.

In the United States, testosterone is a schedule 3 drug due to it’s status as a performance-enhancing drug. So to summarize, yes it is federally illegal to DIY testosterone.

However, in the United States possessing or purchasing testosterone doesn’t inherently make you a wanted criminal. Think about it, basically every single professional bodybuilder you see on social media has bought or taken steroids. There are influencers that are so public about their steroid use, they’re infamous for it.

Simply possessing testosterone is not enough for you to be charged under generally any state jurisdiction. It’s not worth any court’s time.

So in order for charges to be filed against you, you need to do something more. This includes…

  • Being found with steroids on-hand while being searched
  • Distributing or delivering steroids to potential buyers (ie. Drug Trafficking)

In countries like Canada and the UK, personal possession of testosterone is legal, only distribution is prohibited. In other countries, of course the law is different. So you should do research on your respective country.

Will my package of Testosterone get seized?

Depending on the country, testosterone is a controlled substance.

Every country has something called customs, they control the transportation of international packages that either leaves or exits the country. They’re also in charge of package security, they analyze packages and make sure there’s nothing illegal in them.

However, customs only checks international packages. If you were to buy testosterone from within your own country, called domestic sourcing, then there is zero chance of your testosterone getting seized. Even then, if you buy testosterone from a reputable international source there is still a low chance of it getting seized.

What’s the difference between Testosterone Esters? (Ex. Cypionate, Enanthate)

On the site, you will notice different types of testosterone injectables having added suffixes like “Cypionate, Enanthate” at the end. These are called esters. Esters are a byproduct of a chemical reaction called esterification. Esters are added to extend how long a drug continues releasing into your blood stream aswell as improving absorption.

Without esters, the hormone would immediately be absorbed and delivered throughout the body in just a few minutes. Causing an immense spike that will leave as fast as it came. Hormones are slow acting, they take days, weeks and months to finish sending out messages to all the targets within our body, so they need more time. Esters make these drugs usable by extending those few minutes of activity to days, which we can inject at appropriate intervals.

So what’s the difference between these esters?

There are a lot of pharmacokinetic variables that differ between esters. For those who aren’t familiar, pharmacokinetic variables basically means values relating to how the body affects a substance.

Take Half-Life (T 1/2) as an example for this, which represents how many days it takes for a drug to reach 50% of it’s concentration after peak.

For Enanthate and Cypionate, they’re roughly the same, so they utilize the same dosage recommendations. Cypionate has a bit longer Cmax though, which isn’t important.
