I bought 2 bottles and used a low dose of test. Not really sure what range your looking for weekly though. If you use 5g in one bottle that is 21mg of test per ml. 5ml am and 5ml pm will yield about 515mg of test at a 35% absorption rate per week. 2 bottles will last about 6 weeks 515mg of test base is just that 515mg of test there is no ester to worry about so its more like taking in over 600mg of say test e or c per week. I used about 250mg per week while using primobolan and i loved it. it kept my libido sky high and you just feel good a few minutes after using the test.
I switched to injecting because i ran out of the transdermal (i like to run low dose long cycles) and i can honestly say i liked the transdermal better. I just felt better while on it. if you use it for only 6 weeks no HCG is necessary any more than that and you will need some if you want recovery to be smooth and to maintain your natty test levels throughout the cycle. I would throw an AI in there and add 50mg of proviron to free up any bound test.
