What dosage were you at and what was your go to beta blocker?
Well my answer is going to be a little complicated, sorry about that. I've run that type of cycle a few times, and have had issues because sometimes I used two different types of "anavar" during the same cycle and one of them turned out to be superdrol.
Also my body responds very well to exogenous androgens. Every time I have ran a cycle I have used smaller or the same dosages that my training bros use, we generally run the same cycles compound and time wise, and it's not like I am working harder or eating better than they are, but I usually get noticabley better results from the same or less gear (and these guys can eclipse me off cycle)
That being said, I saw great results with 30-40mg/day. Most people would probably want 60-80 for really effective bulking maybe as low as 50. This was with either 350 or 500 test/week depending on the cycle, and still going to need AIs. Eat high protein in a surplus and it's a very effective lean bulk.
The beta-blocker question is also complicated. I use metoprolol, which is a selective beta-1 blocker acting almost exclusively on smooth (ie cardiac) muscle. Beta-blockers can have more sides than ACE inhibitors or ARB meds that most BBers use, however both of these lower free T, so I stay away from them. ACE inhibitors also have additional cardio-protective aspects, specifically making ventricular hypertrophy less prevalent according to some studies, and may also protect the kidneys in certain populations. This explains with good reason why they are so popular with a lot of people. Beta-blockers have the bonus of not lowering free T, but you need to taper up to find the right dose, and there can be both positive and negative ramifications from abruptly stopping them when you are off cycle. It's pretty complicated and I could go into more depth but am already rambling.
Easy quick answer, if you want to go the pharma route for BP control, either 25mg of metoprolol, or if you want to go the more idiot proof ACE route 2.5-5mg of lisinopril. Get these from your
doctor and make sure you ask his advice regarding the matter.
