16 wks is too long bro. your gonna pickle your insides. but also, most of the gains are gonna come between wk 2-4 or up to wk 5 if you run that long. not that there wont be gains after that, they just wont be a substantial and likely to keep. and if gyno prone, look into something more like Methylstenbolone as it doesn't convert to estrogen. im prone and had zero issues gaining 10lbs and keeping almost all of it. you could make some serious gains running 16wks but remember you only got one body and one set of gonads. don't be too hard on them all at once. you could have a lot of difficulty getting them going again leaving you with an inability to make any gains off cycle at all or even losing everything you worked for. if your in it for the long haul just play it safe with 4wkrs and you now the risk is much lower and you know between cycles you wont be stagnant in your gains. best of luck. swol.
p.s. its also kinda overkill doubling SERMs. im a firm believer in sticking to the basics so stick with, in my opinion, the clomid. and do NOT run 100mg like some people say because again, total overkill. 50mg max. you can only stimulate your LH and FSH levels so much and any more could bring about unwanted sides that make you crybaby lol. and can even be detrimental to gains coming off it. coming from a near shutdown to overproductions leaves your "boys" in a state of disarray and they wont know what to do. 50, 35, 35, 17.5ml if using peptide or 50, 50, 25, 25pills. be safe and keep your coin purse full and happy =]
