25 per DAY is NUTS....unless she is a pro. 25 every other day would still be risky but it is done.
25mg every third or forth day would be much safer and still give good gains.
Why not try primo orally, if it can be found, as it is less androgen than winny. 50mg per day ORALLY would be safe. Better yet get the least androgenic injectable, nandrolone, but make sure it is in the fast acting ester phenylprop so if sides come on she can bail out. 25mg of nandrolone every third day would give her very good gains indeed. Or if more safety is wanted then do a single shot of 50-75 mg once per week. Using nandrolone phenylprop in this way still results in good gains but VERY little chance of sides. Do not use nandrolone in the Deca ester because if sides come on then she will have to ride them out for weeks and by that time they may be permanent! That said there are many ladies that do well on 50 mg of deca per week.....but it is best to do the phenylprop ester first in order to find out ones tolerance and then later on one can do the cheaper and more readily available deca.
