From what I've gathered from online research, 5mg a day is very unlikely to cause suppression, but doses higher than that can. Sooo taking a double dose of bridge ON cycle (ie, to replace HCGenerate) is probably fine since you're already suppressed and planning on doing a PCT anyways, but I would be wary of taking a double dose (10mg/day pregnenolone) when you're "off" or as a standalone supp unless you plan on doing a light PCT afterwards. Maybe some ppl wouldn't get suppression on 10mg/day but I wouldn't risk it w/o pct personally. But yeah, pregnenolone can be converted into both progesterone and DHEA (which in turn can be converted into both androgens and estrogens), so it could raise your estrogen/progesterone levels. For this reason I'd stack it with formastanzol or something similar. I'm sure you'll be fine, especially if you didn't take a double dose for the whole 5-6 weeks...
