Testosterone Cypionate was the most common form available to athletes before the scheduling of anabolic steroids in the US. It is a long acting ester of testosterone, and had gained the reputation of being slightly stronger than enanthate and was extremely popular among athletes in the period before scheduling of anabolic steroids.
In the present highly controlled markets, it almost impossible find! The only versions of Cypionate you would be able to find on the black market are Sten from Mexico, which contains 75 mg Cypionate with 25 mg Propionate along with some DHEA, and Testex from Leo in Spain which contains 250 mg Cypionate is a light resistant ampule.
All versions of Upjohn and Steris in multi-dose vials should be looked at closely and with caution as they are very difficult to get on the black market and spurious alternatives and counterfeits are quite easy to obtain.
You could perhaps identify correctly real Steri products as they have the inking STAMPED into the box and the labels cannot be removed from the bottle. Any variation is definitely suspicious and could denote a cheap and possibly dangerous imitation.
A normal running dosage of test Cypionate is generally in the range of 200-600 mg per week. In the days of easier availability at $20 per 10 ml bottle, many users would pop in a whopping 2000 mg per week! This kind of dosage is however extreme and not really needed.
