3 week gap sufficient?

So I’m not a regular user. I’ve rolled exactly 4 times before - 3 times last year (2 in May and then once in November) and once this year (first week of this month).

I’m planning to roll again towards the end of this month, exactly 3 weeks after the last time. Is this gap sufficient, when it comes to safety and feeling the effects of the roll? I don’t plan to do it regularly after that, but would still like to know if I’m rushing it or not. TIA!
