No doubt. As @sh1973 said,it took about 10 to 12 weeks to fully feel the effects and that's what I've read,irrespective of dosage. Six weeks seems to be too short of a therapeutic window. I'm not going to presume anything, just do my weekly injection. My standard would be return of nocturnal erections and morning wood. Sex drive/desire is always there when I'm on testosterone injections.Many guys never even consider low dose because the T clinics have conditioned us to think that anything less than 100mg per week is low despite fact that 52mg per week is in line with average physiological levels.
Thankfully there are bunch of guys on this forum like @sh1973 and @Cataceous and also on other forums (Emeric the bodybuilder) who challenged the status quo and started trying to replicate normal T endogenous production. My guess is that we will see more and more guys gravitating towards lower doses as the word spreads.
