What is Testosterone Cypionate 200 (Astera Labs)?
Astera Labs testosterone cypionate at 200mg/ml, in a 10ml multidose vial. One item covering a full cycle, at the lowest entry price of the long testosterone esters we stock.
Also sold as Test-C, Depo-Testosterone, Depovirin or Jectatest.
The cypionate ester is fractionally larger than enanthate, which makes the release marginally slower. In practice the two behave the same: same dosing, same injection frequency, same role as the base a cycle is built on.
Testosterone Cypionate 200 benefits
One or two injections a week covers it, unlike the short esters
Lowest price of entry among our long testosterone esters
One vial for the cycle instead of ten ampoules to open and dispose of
200mg/ml gives round numbers: 1ml is 200mg, 2.5ml is a 500mg week
Suspended in Miglyol 812, thinner than the oils most competitors use
Testosterone Cypionate 200 dosage
Beginner
300 to 500mg per week, which is 1.5 to 2.5ml
Intermediate
500 to 750mg per week alone, around 500mg when stacked
Advanced
750 to 1000mg per week, run alone rather than stacked
TRT base
100 to 250mg per week
Frequency
Once weekly minimum, twice is better
Half-life
About 8 days
At 200mg/ml a 500mg week is 2.5ml, usually split as 1.25ml twice. That is more oil per injection than the 250 or 300mg/ml options, which is worth knowing if you are sensitive to volume.
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 Cypionate 200 for?
Anyone who wants a testosterone base at the lowest price of entry, and would rather handle one vial than ten ampoules.
Worth being straight about the trade: at 29.00 for 2000mg this is the cheapest box on the shelf, but per milligram it is fractionally more than TESTOMED C 250, and at 200mg/ml you inject more oil for the same dose. Cheaper to start, marginally more over a full cycle.
Before you run it. This replaces your own testosterone production for the cycle and for some time after, so post-cycle therapy is part of the plan, not an optional extra. Testosterone aromatises, which is what the estrogen management guide covers, and bloodwork is how you know where you stand. Not for anyone under 18, and not for women who are pregnant or breastfeeding.
How to use Testosterone Cypionate 200
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.
