Testosterone Enanthate

What is Testosterone Enanthate 300 (Astera Labs)?

Astera Labs testosterone enanthate at 300mg/ml, in a 10ml multidose vial. The same ester everyone runs, in the format that means one item for the whole cycle instead of ten.

Also sold as Test-E, Androtardyl or testosterone enantate.

The enanthate ester is large, which slows the release. One injection keeps levels up for the best part of a week, so this is the ester you run when you want a stable base without thinking about it daily. At 300mg/ml it is more concentrated than the standard 250, which means less oil going in per dose.

Testosterone Enanthate 300 benefits

• 300mg/ml, so a 500mg week is under two millilitres of oil rather than two full ampoules
• One or two injections a week covers it, unlike the short esters
• One vial for the cycle instead of ten ampoules to open and dispose of
• The standard base for a first cycle, where testosterone alone is the right call
• Suspended in Miglyol 812, thinner than the oils most competitors use

Testosterone Enanthate 300 dosage

Beginner

300 to 500mg per week

Intermediate

500 to 750mg per week alone, around 500mg when stacked

Advanced

750 to 1000mg per week, run alone rather than stacked

100 to 250mg per week

Frequency

Once weekly minimum, twice is better

Half-life

7 to 10 days

At 300mg/ml the arithmetic is less round than at 250. 500mg a week is 1.67ml, so most people draw 0.85ml twice weekly rather than trying to hit an exact figure once.

There is no reason to push past the beginner range on a first cycle. The higher figures apply when testosterone is doing all the work alone.

Who is Testosterone Enanthate 300 for?

Anyone running a testosterone base who would rather manage one vial than ten ampoules, and who wants the higher concentration so there is less oil going into the muscle each time.

If you would rather each dose stayed sealed and sterile until the moment you use it, TESTOMED E 250 is the same compound as 10 single-use ampoules at 250mg/ml.

How to use Testosterone Enanthate 300

Intramuscular injection, once or twice weekly. Wipe the vial stopper with alcohol before every draw, and use a fresh needle to draw and another to inject. Rotate between glutes, quads and delts. The injection technique guide covers the technique.
