Yes, but timing matters. Progesterone supplementation typically begins 1–3 days post-ovulation to support luteal phase endometrial thickening. Follistatin should be administered starting on cycle day 21 (mid-luteal phase) to coincide with the implantation window. The two don't interact pharmacologically, but both require subcutaneous or intramuscular injection—patients should rotate injection sites to prevent lipohypertrophy. Combining them into a single syringe is not recommended unless both are formulated in identical carrier solutions.

Administer the missed dose as soon as you remember if fewer than 48 hours have passed. If more than 48 hours have elapsed, skip the missed dose and resume your regular schedule. Tβ4's mechanism (Treg upregulation) builds cumulatively over weeks—missing a single dose doesn't erase prior progress, but missing multiple doses reduces therapeutic plasma levels below the threshold needed to suppress uNK cell activity. Consistency matters more than perfection.

Follistatin may improve follicle recruitment if your AMH is below 1.0 ng/mL and standard FSH protocols yield fewer than 5 oocytes per cycle. The mechanism. Activin neutralization. Enhances granulosa cell responsiveness to FSH, potentially increasing antral follicle count by 18–22% based on early-phase trials. This is not egg quality improvement. It's recruitment optimization. If your ovarian reserve is severely depleted (AMH below 0.3 ng/mL), even enhanced FSH sensitivity cannot recruit follicles that no longer exist.
