If the cyp is vet grade than I guess it depends on what kind of T-200 you have. Most will tell you to take almost anything over Brovel T-200. If it's Tornell T-200 against, say, Ttokyo Cyp, than I suppose it's a toss up. T-200 is Enanthate. Enanthate and Cyp are almost identical in effect, at least for me. I would say your descission should be based on the following:
Assuming that what you have is real, if it's human grade Cyp, I would take that over a vet drug.
If they are both vet drugs, you would want to consider which is the better brand, strength per ml, and price. For instance, if it's Tt cyp @ 100mg/ml 10ml btl against Tornell T-200 which is 200mg/ml(sort of) 10ml btl(sort of) and the price is identical, than I would take the T-200 because of the 1000mg (sort of) of active product it delivers over the Tt brand. If it's the 200mg/ml Tt Cyp, I'll take it over the Tornell T-200 because, with prices being equal, I prefer the Tt brand.
If it's Brovel T-200, I'll take the Tt at an equivalent price in any strength because of brand preference.
I do not know what brands you have, etc. This is just one of the ways I would choose a given product over another. It's pretty much like shoping for anything else for me.
