What is Long Acting Mix 500 (Astera Labs)?
Long Acting Mix puts testosterone, drostanolone and trenbolone enanthate into one vial, so a full recomposition cycle is two injections a week rather than six.
The three long esters are matched so they release on the same timeline, which is what makes a single injection work. Testosterone is the base, drostanolone hardens and holds off some estrogen conversion, and trenbolone does the heavy lifting on tissue and fat. At 500mg/ml this is a concentrated oil and one millilitre is a real dose.
Long Acting Mix benefits
- A complete cutting or recomposition stack in a single injection
- Two injections a week instead of six across three separate vials
- The three enanthate esters release on the same timeline, so levels stay matched
- Drostanolone and trenbolone are both non-aromatising, so only the testosterone portion converts

Read the dose per compound rather than per millilitre. 2ml a week is 400mg of testosterone, 400mg of drostanolone and 200mg of trenbolone, which is a serious cycle and where most people should sit.
The thing nobody says about blends is that the ratio is fixed and you cannot change it. If you want more trenbolone you have to take more testosterone and more drostanolone with it. On separate vials you would simply raise one. That is the real trade-off you are making for the convenience of a single injection.

Who is Long Acting Mix for?
Experienced users cutting or recomposing who already know how they respond to all three compounds individually. The ratio suits a lean-out rather than a bulk, because two of the three do nothing for water or appetite.
If the ratio does not match what you want, the components are sold separately: testosterone enanthate, drostanolone enanthate and trenbolone enanthate. The Short Acting Mix is the same three compounds on fast esters.
How to use Long Acting Mix
Intramuscular injection, twice weekly, into a large muscle. At 500mg/ml this is a thick oil, so inject slowly and let the vial reach room temperature first. The injection technique guide covers it.
