lean bulk (small calorie surplus) on my first ever cycle (500mg/test) while keeping my reta at 4mg every 6 days. hoping most of my weight gained will be muscle and then i'll go on another cut after. that's the plan. Waiting for rebound water weight to come on the scale then after that I don't plan on adding more than 10-15lb during my 12-16 week lean bulk.
So currently i'm 165lb, theoretically once i get my "water weight" back im expecting to be around 170, i won't go further than 180-185.
You did not say how tall you are, but, assuming you are average height or so, at 165 pounds, there is no reason you cannot do both.
A lot of guys posting here are well past their natural weights and need to actively do one or the other.
At 165 pounds, most guys can do both at the same time, add muscle and decrease fat. It takes self control and consistency in the diet. Every day. Boring food used as fuel, and your food determined not by what you want to eat, but programming from your calorie tracker hitting exact calorie and macro counts each and every day with no deviation. That and 500mg of testosterone will do wonders over 10-12 weeks.
I have never tried reta, and I have no experience with it, so I cannot comment on whether your use of it is good or bad in this context.
No need to "bulk" in the traditional sense that bodybuilders mean when trying to increase their weight from 215 to over 230.
I have long said that beginners to steroids can do both, and I mean it. I did, and I had a base of lifting for decades and already was reasonably lean, but I added bodyweight (quite a bit, actually) and came out visibly much leaner.
My diet was very tight and boring and controlled with
no cheating for three months, though.
Some guys from another steroid board took pity on me (after informing me my diet was "crap" and so on, until I finally posted, "Hey, that doesn't help me," somebody laid out one of those boring chicken and rice type old school diets, and I stuck to it, and, well, damn it, it worked - I actually started the diet a month before my first cycle, and it was already making changes during that month, and the 500mg of testosterone just accelerated those changes into overdrive)
