Category A: Studies that were well-controlled and met expectations revealed no risk to the foetus `in either the first or second trimester.Â
<b>Category B: There were a lack of studies on pregnant women and no evidence of risk to the foetus in animal experiments.  Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.  Â

PharmacologyÂ
It is an aminoacid peptide indicated in treating various ailments.Â
PharmacodynamicsÂ
It is a protein made up of 28 amino acids that was first found in bovine thymus extract along with other peptides that boost the immune system. Research done in a lab has demonstrated that it can influence the growth and advancement of T-cells which generates Th1 cytokines like interleukin-two and interferon-gamma. It also kickstart the natural killer cells’ ability to destroy harmful cells.Â
