Suggested use: Practical guidelines for use based on experience: Not for Use by Under 18s Why – Short answer there should be no need as testosterone will be at a high level and therefore no likely no additional benefit will be seen. Focus on the basics of training right, eating right, sleeping well and doing this on a consistent basis. Not For Female Athletes Why ? In women, AGF-1 is more likely to increase oestrogen levels which is detrimental from an athletic performance perspective. Does AGF-1 increase fertility? Studies suggest that in infertile men DAA can increase testosterone, sperm mobility and conception rates. D-Aspartate, a Key Element for the Improvement of Sperm Quality, D’Aniello et al, 2012. Advances in sexual Healing We have had feedback from multiple users who were struggling to conceive with their partners and seemed to have success following AGF-1 use. We are not selling in for this purpose or making any claims But, we thought it wise to give you the heads up so you are aware. To Cycle or Not? Males Under 30s Suggested use: 1 month on, 1 month off. There is no negative feedback cycle of testosterone with AGF-1 use so in theory there is no need to cycle. However, as studies suggest the rise in testosterone from DAA is temporary for men with normal test levels, it may make sense to cycle 1-2 months on, one off. However, when using with players and athletes I would always dictate use with the calendar, e.g. players will use for preseason blocks 4-6 weeks and also continually over a camp gain such as six nations or Lions Tour. If you are on strict calorie deficit eating plan this can reduce test levels so use over the diet may be beneficial. I have also used with good effect during injury times to try and maintain lean muscle combined with a high protein intake (3g per kg) and also with creatine and Omega 3.
