Testosterone Test Results - Need Advice

Had my testosterone levels checked yesterday (at 12.30 not fasted) and results were as follows:

Free testosterone: 210.6 pmol/l Total testosterone: 10.9 nmol/l SHBG: 34.3 nmol/l

Had a test done just over two months ago (15 August ) (test done first thing in the morning while fasted) and my levels were:

Free: 232.4 pmol/l Total: 12.5 nmol/l SHBG: 37.4 nmol/l

Prior to the test done on the 15th of August my levels were tanked from doing a SARMS cycle (apparently AC262) which I do not think is what I actually received from the supplier. Those results were:

Free: <14 pmol/l Total: <0.4 nmol/l SHBG: 5.3 nmol/l

My levels were so low in May

I had been losing weight over the period of a year and a half and went from 86kg to 69.9kg at my lowest. Currently I'm doing a lean bulk and sitting at 72kg, 13% body fat. Don't know if the weight loss also added to my levels lowering. Before my levels tanked I wasn't much higher than the results in my August and September tests.

My GP wants me to go on testosterone cream but I'm hesitant as then it's a live long commitment.

Since I am trying to build muscle I am tempted to go on TRT but does testosterone cream also help with building muscle or are injections the only way to go?

With my latest testosterone results should I be on TRT? Can I build decent muscle mass at these levels?

Although I'm tempted to go on TRT I would prefer to try raise my levels naturally. I'm currently taking tongkat Ali, magnesium, zinc, ashwaganda and vitamin d3 with k2.

I eat well and track everything I eat. All my macros are based with hypertrophy in mind.

Any help would be greatly appreciated

Thank you
