This is normal for the most part. It is nearly impossible to keep all your gains after a cycle especially a short oral only cycle. You will loose muscle glycogen, water, and mass to a degree if your diet is not adjusted to compensate for your new mass. The libido problem is a result of shutdown or possibly even a lack of estrogen as EPI is an AI, and you actually need healthy levels of estrogen to function sexually as a male. Lack of libido should subside shortly, if it does not it may be time to look into a SERM. I laid out an OTC PCT for you, but also included my usual recommendation to have a SERM on hand. Give it a week or so. Even with a solid PCT it takes the body a some time to return to normal. Missing the feeling of being on is also normal, it happens to all of us. Its the cost of going from the metal outlook of a alpha male superhuman back to normal. Keep your training intensity up, keep your diet clean, and calorie intake raised.
