due to price/scarcity I've been looking at alternatives to the usual 5000/10000iu flakons (pregnyl, choriomon etc) offered by sources:

1. pregnyl comes in 3 x 1500iu amps; as 1500iu is not usual dosage, can they be reconstituted with bac. water & preloaded into pins of i.e. 500iu and stored for ~10 days without risk of losing sterility/decomposing the syringe stopper?

2. ovitrelle comes in a single 6500iu pen and the instruction manual states it's for singular injection only, can they be used safely for up to 8 weeks? and as the needle can't be switched, is dulling not an issue?
 
All hCG is typically meant to be injected all at once for female fertility. You should always have a separate vial to store the hCG.
