Choriogonadotropin apha..is it same as HCG? (Ovitrelle)

[Nitrom]

Since pregnyl was out of stock i could only get Ovitrelle ,its spanish version that supposedly is simmilar TO hcg but it states that its choriogonadrotropin alpha? a synthetic version...i got a prefilled suringe ...

now the problem that i dont understand is it any good and can it be used in same purpose during cycle?

also it is 6500 IU one ....does IU for HCG count as same as for this one ,since i planned taking this 250Iu 2x per week
