your test is low. it wouldnt hurt to have it checked again before you go on so that you have a good baseline understanding of where you're naturally at. after you cycle, you'll never know if you've reached full recovery without knowing what that numer is. the fad diet may have effected your levels...maybe not. only one way to tell. your cycle looks good. make sure you practice proper sterile technique and there are many guides with pics online to show you how to properly inject. only one change in would make with your cycle is to plan to back the hcg and clomid up to begin pct 2 wks after your last injection. for liv 52, just take the regular daily dose and for milk thistle, take 1000mg ed. split it up however you want. you dont need to take it several times a day if its a hastle.
for your protein, on or off cycle, you should be getting 1.5g to 2g of protein per lb of lean mass of the weight you are trying to acheive. i didnt do the math but i'm sure you should be getting more than 250g a day. take your daily protein and split it up into meals eaten every 2-3 hours. it's not easy but if you want to grow, this is what you'll do. get most of it from solid foods. its hard. believe me i know. i consume close to 500g a day.
